Complex ML projects rely on ML pipelines to train and test ML models. An ML pipeline is a sequence of stages where each stage performs a particular task, such as data loading,  pre-processing, ML model training and testing stages. Each stage can have multiple Executions.  Each Execution,
 
     
  • consume inputs and produce outputs.
    •  
  • are parametrized by parameters that guide the process of producing outputs.
    •  
 
 
CMF uses the abstractions of Pipeline,Context and Executions to store the metadata of complex ML pipelines. Each pipeline has a name. Users provide it when they initialize the CMF. Each stage is represented by a Context object. Metadata associated with each run of a stage is captured in the Execution object. Inputs and outputs of Executions can be logged as dataset, model or metrics. While parameters of executions are recorded as properties of executions.
 
 1 Init2 Stage type3 New execution4 Log Artifacts 
Start tracking the pipeline metadata by initializing the CMF runtime. The metadata will be associated with the  pipeline named test_pipeline. 
from cmflib.cmf import Cmf\nfrom ml_metadata.proto import metadata_store_pb2 as mlpb\n\ncmf = Cmf(\n    filename=\"mlmd\",\n    pipeline_name=\"test_pipeline\",\n) \n
 
Before we can start tracking metadata, we need to let CMF know about stage type. This is not yet associated with  this particular execution. 
context: mlmd.proto.Context = cmf.create_context(\n    pipeline_stage=\"train\"\n)\n
 
Now we can create a new stage execution associated with the train stage. The CMF always creates a new execution, and will adjust its name, so it's unique. This is also the place where we can log execution parameters like seed, hyper-parameters etc . 
execution: mlmd.proto.Execution = cmf.create_execution(\n    execution_type=\"train\",\n    custom_properties = {\"num_epochs\": 100, \"learning_rate\": 0.01}\n)\n
 
Finally, we can log an input (train dataset), and once trained, an output (ML model) artifacts. 
cmf.log_dataset(\n    'artifacts/test_dataset.csv',   # Dataset path \n    \"input\"                         # This is INPUT artifact\n)\ncmf.log_model(\n    \"artifacts/model.pkl\",          # Model path \n    event=\"output\"                  # This is OUTPUT artifact\n)\n

Import CMF. 
from cmflib import cmf\n
 
Initialize CMF. The CMF object is responsible for managing a CMF backend to record  the pipeline metadata. Internally, it creates a pipeline abstraction that groups individual stages and their executions.  All stages, their executions and produced artifacts will be associated with a pipeline with the given name. 
cmf = cmf.Cmf(\n   filename=\"mlmd\",                # Path to ML Metadata file.\n   pipeline_name=\"mnist\"           # Name of a ML pipeline.\n)                                                       \n
 
Define a stage. An ML pipeline can have multiple stages, and each stage can be associated with multiple executions. A stage is like a class in the world of object-oriented programming languages. A context (stage description) defines  what this stage looks like (name and optional properties), and is created with the  create_context method. 
context = cmf.create_context(\n    pipeline_stage=\"download\",     # Stage name\n    custom_properties={            # Optional properties\n        \"uses_network\": True,      #  Downloads from the Internet\n        \"disk_space\": \"10GB\"       #  Needs this much space\n    }\n)\n
 
Create a stage execution. A stage in ML pipeline can have multiple executions. Every run is marked as an execution.  This API helps to track the metadata associated with the execution, like stage parameters (e.g., number of epochs and  learning rate for train stages). The stage execution name does not need to be the same as the name of its context. Moreover, the CMF will adjust this name to ensure every execution has a unique name. The CMF will internally associate this execution with the context created previously. Stage executions are created by calling the  create_execution method. 
execution = cmf.create_execution(\n    execution_type=\"download\",            # Execution name.\n    custom_properties = {                 # Execution parameters\n        \"url\": \"https://a.com/mnist.gz\"   #  Data URL.\n    }\n)\n
 
Log artifacts. A stage execution can consume (inputs) and produce (outputs) multiple artifacts (datasets, models and  performance metrics). The path of these artifacts must be relative to the project (repository) root path. Artifacts  might have optional metadata associated with them. These metadata could include feature statistics for ML datasets, or useful parameters for ML models (such as, for instance, number of trees in a random forest classifier). 
 
     
  •  
    Datasets are logged with the log_dataset method.     
    cmf.log_dataset('data/mnist.gz', \"input\", custom_properties={\"name\": \"mnist\", \"type\": 'raw'})\ncmf.log_dataset('data/train.csv', \"output\", custom_properties={\"name\": \"mnist\", \"type\": \"train_split\"})\ncmf.log_dataset('data/test.csv', \"output\", custom_properties={\"name\": \"mnist\", \"type\": \"test_split\"})\n
     
    •  
  •  
    ML models produced by training stages are logged using log_model API. ML models can be    both input and output artifacts. The metadata associated with the artifact could be logged as an optional argument.     
    # In train stage\ncmf.log_model(\n   path=\"model/rf.pkl\", event=\"output\", model_framework=\"scikit-learn\", model_type=\"RandomForestClassifier\", \n   model_name=\"RandomForestClassifier:default\" \n)\n\n# In test stage\ncmf.log_model(\n   path=\"model/rf.pkl\", event=\"input\" \n)\n
     
    •  
  •  
    Metrics of every optimization step (one epoch of Stochastic Gradient Descent, or one boosting round in    Gradient Boosting Trees) are logged using log_metric API.     
    #Can be called at every epoch or every step in the training. This is logged to a parquet file and committed at the \n# commit stage.\n\n#Inside training loop\nwhile True: \n     cmf.log_metric(\"training_metrics\", {\"loss\": loss}) \ncmf.commit_metrics(\"training_metrics\")\n
     
    •  
  •  
    Stage metrics, or final metrics, are logged with the log_execution_metrics   method. These are final metrics of a stage, such as final train or test accuracy.      
    cmf.log_execution_metrics(\"metrics\", {\"avg_prec\": avg_prec, \"roc_auc\": roc_auc})\n
     
    •  
 
Dataslices are intended to be used to track subsets of the data. For instance, this can be used to track and compare accuracies of ML models on these subsets to identify model bias. Data slices are created with  the create_dataslice method. 
dataslice = cmf.create_dataslice(\"slice-a\")\nfor i in range(1, 20, 1):\n    j = random.randrange(100)\n    dataslice.add_data(\"data/raw_data/\"+str(j)+\".xml\")\ndataslice.commit()\n

CMF Query communicates with the MLMD database and implements basic search and retrieval functionality.
 
This class has been designed to work with the CMF framework. CMF alters names of pipelines, stages and artifacts in various ways. This means that actual names in the MLMD database will be different from those originally provided by users via CMF API. When methods in this class accept name parameters, it is expected that values of these parameters are fully-qualified names of respective entities.

Common metadata framework has the following components:
 
     
  • Metadata Library exposes API\u2019s to track the pipeline metadata. It also provides API\u2019s to query    the stored metadata. 
    •  
  • Local Client interacts with the server to pull or push metadata from or to the remote store. 
    •  
  • Central Server interacts with all the remote clients and is responsible to merge the metadata   transferred by the remote client and manage the consolidated metadata.  
    •  
  • Central Repositories hosts the code, data and metadata.
    •  
 
"},{"location":"architecture/components/#metadata-library","title":"Metadata Library","text":"
The API\u2019s and the abstractions provided by the library enables tracking of pipeline metadata. It tracks the stages in  the pipeline, the input and output artifacts at each stage and metrics. The framework allows metrics to be tracked both  at coarse and fine-grained intervals. It could be a stage metrics, which could be captured at the end of a stage or  fine-grained metrics which is tracked per step (epoch) or at regular intervals during the execution of the stage. 
 
The metadata logged through the APIs are written to a backend relational database. The library also provides API\u2019s to  query the metadata stored in the relational database for the users to inspect pipelines.   
 
In addition to explicit tracking through the API\u2019s library also provides, implicit tracking. The implicit tracking  automatically tracks the software version used in the pipelines. The function arguments and function return values can  be automatically tracked by adding metadata tracker class decorators on the functions. 
 
Before writing the metadata to relational database, the metadata operations are journaled in the metadata journal log.  This enables the framework to transfer the local metadata to the central server. 
 
All artifacts are versioned with a data versioning framework (for e.g., DVC). The content hash of the artifacts are  generated and stored along with the user provided metadata. A special artifact metadata file called a \u201c.dvc\u201d file is  created for every artifact (file / folder) which is added to data version management system. The .dvc file contains the content hash of the artifact.  
 
For every new execution, the metadata tracker creates a new branch to track the code. The special metadata file created  for artifacts, the \u201c.dvc\u201d file is also committed to GIT and its commit id is tracked as a metadata information. The artifacts are versioned through the versioning of its metadata file. Whenever there is a change in the artifact,  the metadata file is modified to reflect its current content hash, and the file is tracked as a new version of the metadata file.  
 
The metadata tracker automatically tracks the start commit when the library was initialized and creates separate commit  for each change in the artifact along the experiment. This helps to track the transformations on the artifacts along the different stages in the pipeline. 
"},{"location":"architecture/components/#local-client","title":"Local Client","text":"
The metadata client interacts with the metadata server. It communicates with the server, for synchronization of metadata.  
 
After the experiment is completed, the user invokes the \u201cCmf push\u201d command to push the collected metadata to the remote. This transfers the existing metadata journal to the server.  
 
The metadata from the central repository can be pulled to the local repository, either using the artifacts or using the  project as the identifier or both. 
 
When artifact is used as the identifier, all metadata associated with the artifacts currently present in the branch of  the cloned Git repository is pulled from the central repository to the local repository. The pulled metadata consist of  not only the immediate metadata associated with the artifacts, it contains the metadata of all the artifacts in its  chain of lineage. 
 
When project is used as the identifier, all the metadata associated with the current branch of the pipeline code that  is checked out is pulled to the local repository. 
"},{"location":"architecture/components/#central-server","title":"Central Server","text":"
The central server, exposes REST API\u2019s that can be called from the remote clients. This can help in situations where the connectivity between the core datacenter and the remote client is robust. The remote client calls the API\u2019s exposed by the central server to log the metadata directly to the central metadata repository.  
 
Where the connectivity with the central server is intermittent, the remote clients log the metadata to the local  repository. The journaled metadata is pushed by the remote client to the central server. The central server, will  replay the journal and merge the incoming metadata with the metadata already existing in the central repository. The  ability to accurately identify the artifacts anywhere using their content hash, makes this merge robust. 
"},{"location":"architecture/components/#central-repositories","title":"Central Repositories","text":"
The common metadata framework consist of three central repositories for the code, data and metadata. 
"},{"location":"architecture/components/#central-metadata-repository","title":"Central Metadata repository","text":"
Central metadata repository holds the metadata pushed from the distributed sites. It holds metadata about all the  different pipelines that was tracked using the common metadata tracker.  The consolidated view of the metadata stored  in the central repository, helps the users to learn across various stages in the pipeline executed at different  locations. Using the query layer that is pointed to the central repository, the users gets the global view of the  metadata which provides them with a deeper understanding of the pipelines and its metadata.  The metadata helps to  understand nonobvious results like performance of a dataset with respect to other datasets, Performance of a particular pipeline with respect to other pipelines etc. 
"},{"location":"architecture/components/#central-artifact-storage-repository","title":"Central Artifact storage repository","text":"
Central Artifact storage repository stores all the artifacts related to experiment. The data versioning framework (DVC)  stores the artifacts in a content addressable layout. The artifacts are stored inside the folder with name as the first two characters of the content hash and the name of the artifact as the remaining part of the content hash. This helps  in efficient retrieval of the artifacts.   
"},{"location":"architecture/components/#git-repository","title":"Git Repository","text":"
Git repository is used to track the code. Along with the code, the metadata file of the artifacts which contain the  content hash of the artifacts are also stored in GIT. The Data versioning framework (dvc) would use these files to  retrieve the artifacts from the artifact storage repository.

Interactions in data pipelines can be complex. The Different stages in the pipeline, (which may not be next to each  other) may have to interact to produce or transform artifacts. As the artifacts navigates and undergo transformations  through this pipeline, it can take a complicated path, which might also involve bidirectional movement across these  stages. Also, there could be dependencies between the multiple stages, where the metrics produced by a stage could influence the metrics at a subsequent stage.  It is important to track the metadata across a pipeline to provide features like,  lineage tracking, provenance and reproducibility.  
 
The tracking of metadata through these complex pipelines have multiple challenges, some of them being,  
 
     
  • Each stage in the pipeline could be executed in a different datacenter or an edge site having intermittent connection    to the core datacenter.   
    •  
  • Each stage in the pipeline could be possibly managed by different teams.  
    •  
  • The artifacts (input or output) needs to be uniquely identified across different sites and across multiple pipelines. 
    •  
 
Common metadata framework (CMF) addresses the problems associated with tracking of pipeline metadata from distributed  sites and tracks code, data and metadata together for end-to-end traceability.   
 
The framework automatically tracks the code version as one of the metadata for an execution. Additionally, the data  artifacts are also versioned automatically using a data versioning framework (like DVC) and the metadata regarding the data version is stored along with the code. The framework stores the Git commit id of the metadata file associated with  the artifact and content hash of the artifact as metadata. The framework provides API\u2019s to track the hyperparameters and other metadata of pipelines.  Therefore, from the metadata stored, users can zero in on the hyperparameters, code  version and the artifact version used for the experiment. 
 
Identifying the artifacts by content hash allows the framework, to uniquely identify an artifact anywhere in the  distributed sites. This enables the metadata from the distributed sites to be precisely merged to a central repository, thereby providing a single global metadata from the distributed sites.   
 
On this backbone, we build the Git like experience for metadata, enabling users to push their local metadata to the  remote repository, where it is merged to create the global metadata and pull metadata from the global metadata to the  local, to create a local view, which would contain only the metadata of interest. 
 
The framework can be used to track various types of pipelines such as data pipelines or AI pipelines.

Object storage is an abstraction layer above the file system and helps to work with data using API. MinIO is the fastest way to start working with object storage. It is compatible with S3, easy to deploy, manage locally, and upscale if needed.
 
Follow the below mentioned steps to set up a MinIO server:
 
     
  1.  
    Copy contents of the example-get-started directory to a separate directory outside the cmf repository.
     
    2.  
  2.  
    Check whether cmf is initialized.    
    cmf init show\n
        If cmf is not initialized, the following message will appear on the screen.    
    'cmf' is not configured.\nExecute the 'cmf init' command.\n
     
    3.  
  3.  
    Execute the following command to initialize the MinIO S3 bucket as a CMF artifact repository.     
    cmf init minioS3 --url s3://dvc-art --endpoint-url http://x.x.x.x:9000 --access-key-id minioadmin --secret-key minioadmin --git-remote-url https://github.com/user/experiment-repo.git --cmf-server-url http://x.x.x.x:8080  --neo4j-user neo4j --neo4j-password password --neo4j-uri bolt://localhost:7687\n
     
    4.  
 
Here, \"dvc-art\" is provided as an example bucket name. However, users can change it as needed, if the user chooses to change it, they will need to update the Dockerfile for minioS3 accordingly.
 
     
  1.  
    Execute cmf init show to check the CMF configuration. The sample output looks as follows:    
    remote.minio.url=s3://bucket-name\nremote.minio.endpointurl=http://localhost:9000\nremote.minio.access_key_id=minioadmin\nremote.minio.secret_access_key=minioadmin\ncore.remote=minio\n
     
    2.  
  2.  
    Build a MinIO server using a Docker container. docker-compose.yml available in example-get-started directory provides two services: minio and aws-cli.    User will initialise the repository with bucket name, storage URL, and credentials to access MinIO.
     
    3.  
  3. Execute the following command to start the docker container. MYIP variable is the IP address of the machine on which you are executing the following command. Following command requires root privileges.    
    MYIP= XX.XX.XXX.XXX docker-compose up\n
        or    
    MYIP= XX.XX.XXX.XXX docker compose up\n
        After executing the above command, following messages confirm that MinIO is up and running. 
    Also you can adjust $MYIP in examples/example-get-started/docker-compose.yml to reflect the server IP and run the docker compose command without specifying 
     
    4.  
  4.  
    Login into remote.minio.endpointurl (in the above example - http://localhost:9000) using access-key and secret-key mentioned in cmf configuration.

SSH (Secure Shell) remote storage refers to using the SSH protocol to securely access and manage files and data on a remote server or storage system over a network. SSH is a cryptographic network protocol that allows secure communication and data transfer between a local computer and a remote server.
 
Proceed with the following steps to set up a SSH Remote Repository:
 
     
  1. Get started with initializing project directory with SSH repo.

    Install Docker Engine with non root user privileges.
     
    3.  
  3. Install Docker Compose Plugin. 
    In earlier versions of docker compose, docker compose was independent of docker. Hence, docker-compose was command. However, after introduction of Docker Compose Desktop V2, compose command become part of docker engine. The recommended way to install docker compose is installing a docker compose plugin on docker engine. For more information - Docker Compose Reference.

    3.  
  3.  
    Execute following command to start both the containers. IP variable is the IP address and hostname is host name of the machine on which you are executing the following command.    You can use either way.    
    IP=200.200.200.200 docker compose -f docker-compose-server.yml up\n           OR\nhostname=host_name docker compose -f docker-compose-server.yml up\n
     
    Replace docker compose with docker-compose for older versions. Also you can adjust $IP in docker-compose-server.yml to reflect the server IP and run the docker compose command without specifying      IP=200.200.200.200.

Common Metadata Ontology (CMO) is proposed to integrate and aggregate the pipeline metadata from various sources such as Papers-with-code, OpenML and Huggingface. CMF's data model is a manifestation of CMO which is specifically designed to capture the pipeline-centric metadata of AI pipelines. It consists of nodes to represent a pipeline, components of a pipeline (stages), relationships to capture interaction among pipeline entities and properties. CMO offers interoperability of diverse metadata, search and recommendation with reasoning capabilities. CMO offers flexibility to incorporate various executions implemented for each stage such as dataset preprocessing, feature engineering, training (including HPO), testing and evaluation. This enables robust search capabilities to identify the best execution path for a given pipeline. Additionally, CMO also facilitates the inclusion of additional semantic and statistical properties to enhance the richness and comprehensiveness of the metadata associated with them. The overview of CMO can be found below.

This example depends on the following packages: git. We also recommend installing  anaconda to manage python virtual environments. This example was tested in the following environments: 
 
     
  • Ubuntu-22.04 with python-3.10
    •  
 
This example demonstrates how CMF tracks a metadata associated with executions of various machine learning (ML)  pipelines. ML pipelines differ from other pipelines (e.g., data Extract-Transform-Load pipelines) by the presence of ML steps, such as training and testing ML models. More comprehensive ML pipelines may include steps such as deploying a trained model and tracking its inference parameters (such as response latency, memory consumption etc.). This example,  located here implements a simple pipeline consisting of four steps:
 
     
  • The parse step splits   the raw data into    train and test raw datasets for training and testing a machine learning model. This step registers one   input artifact (raw dataset) and two output artifacts (train and test datasets). 
    •  
  • The featurize   step creates two machine learning splits - train and test splits - that will be used by an ML training algorithm to   train ML models. This step registers two input artifacts (raw train and test datasets) and two output artifacts (   train and test ML datasets). 
    •  
  • The next train step   trains an ML model (random forest classifier). It registers one input artifact (train ML dataset) and one   output artifact (trained ML model).
    •

Complex ML projects rely on ML pipelines to train and test ML models. An ML pipeline is a sequence of stages where each stage performs a particular task, such as data loading,  pre-processing, ML model training and testing stages. Each stage can have multiple Executions.  Each Execution,
 
     
  • consume inputs and produce outputs.
    •  
  • are parametrized by parameters that guide the process of producing outputs.
    •  
 
 
CMF uses the abstractions of Pipeline,Context and Executions to store the metadata of complex ML pipelines. Each pipeline has a name. Users provide it when they initialize the CMF. Each stage is represented by a Context object. Metadata associated with each run of a stage is captured in the Execution object. Inputs and outputs of Executions can be logged as dataset, model or metrics. While parameters of executions are recorded as properties of executions.
 
 1 Init2 Stage type3 New execution4 Log Artifacts 
Start tracking the pipeline metadata by initializing the CMF runtime. The metadata will be associated with the  pipeline named test_pipeline. 
from cmflib.cmf import Cmf\nfrom ml_metadata.proto import metadata_store_pb2 as mlpb\n\ncmf = Cmf(\n    filename=\"mlmd\",\n    pipeline_name=\"test_pipeline\",\n) \n
 
Before we can start tracking metadata, we need to let CMF know about stage type. This is not yet associated with  this particular execution. 
context: mlmd.proto.Context = cmf.create_context(\n    pipeline_stage=\"train\"\n)\n
 
Now we can create a new stage execution associated with the train stage. The CMF always creates a new execution, and will adjust its name, so it's unique. This is also the place where we can log execution parameters like seed, hyper-parameters etc . 
execution: mlmd.proto.Execution = cmf.create_execution(\n    execution_type=\"train\",\n    custom_properties = {\"num_epochs\": 100, \"learning_rate\": 0.01}\n)\n
 
Finally, we can log an input (train dataset), and once trained, an output (ML model) artifacts. 
cmf.log_dataset(\n    'artifacts/test_dataset.csv',   # Dataset path \n    \"input\"                         # This is INPUT artifact\n)\ncmf.log_model(\n    \"artifacts/model.pkl\",          # Model path \n    event=\"output\"                  # This is OUTPUT artifact\n)\n

Import CMF. 
from cmflib import cmf\n
 
Initialize CMF. The CMF object is responsible for managing a CMF backend to record  the pipeline metadata. Internally, it creates a pipeline abstraction that groups individual stages and their executions.  All stages, their executions and produced artifacts will be associated with a pipeline with the given name. 
cmf = cmf.Cmf(\n   filename=\"mlmd\",                # Path to ML Metadata file.\n   pipeline_name=\"mnist\"           # Name of a ML pipeline.\n)                                                       \n
 
Define a stage. An ML pipeline can have multiple stages, and each stage can be associated with multiple executions. A stage is like a class in the world of object-oriented programming languages. A context (stage description) defines  what this stage looks like (name and optional properties), and is created with the  create_context method. 
context = cmf.create_context(\n    pipeline_stage=\"download\",     # Stage name\n    custom_properties={            # Optional properties\n        \"uses_network\": True,      #  Downloads from the Internet\n        \"disk_space\": \"10GB\"       #  Needs this much space\n    }\n)\n
 
Create a stage execution. A stage in ML pipeline can have multiple executions. Every run is marked as an execution.  This API helps to track the metadata associated with the execution, like stage parameters (e.g., number of epochs and  learning rate for train stages). The stage execution name does not need to be the same as the name of its context. Moreover, the CMF will adjust this name to ensure every execution has a unique name. The CMF will internally associate this execution with the context created previously. Stage executions are created by calling the  create_execution method. 
execution = cmf.create_execution(\n    execution_type=\"download\",            # Execution name.\n    custom_properties = {                 # Execution parameters\n        \"url\": \"https://a.com/mnist.gz\"   #  Data URL.\n    }\n)\n
 
Log artifacts. A stage execution can consume (inputs) and produce (outputs) multiple artifacts (datasets, models and  performance metrics). The path of these artifacts must be relative to the project (repository) root path. Artifacts  might have optional metadata associated with them. These metadata could include feature statistics for ML datasets, or useful parameters for ML models (such as, for instance, number of trees in a random forest classifier). 
 
     
  •  
    Datasets are logged with the log_dataset method.     
    cmf.log_dataset('data/mnist.gz', \"input\", custom_properties={\"name\": \"mnist\", \"type\": 'raw'})\ncmf.log_dataset('data/train.csv', \"output\", custom_properties={\"name\": \"mnist\", \"type\": \"train_split\"})\ncmf.log_dataset('data/test.csv', \"output\", custom_properties={\"name\": \"mnist\", \"type\": \"test_split\"})\n
     
    •  
  •  
    ML models produced by training stages are logged using log_model API. ML models can be    both input and output artifacts. The metadata associated with the artifact could be logged as an optional argument.     
    # In train stage\ncmf.log_model(\n   path=\"model/rf.pkl\", event=\"output\", model_framework=\"scikit-learn\", model_type=\"RandomForestClassifier\", \n   model_name=\"RandomForestClassifier:default\" \n)\n\n# In test stage\ncmf.log_model(\n   path=\"model/rf.pkl\", event=\"input\" \n)\n
     
    •  
  •  
    Metrics of every optimization step (one epoch of Stochastic Gradient Descent, or one boosting round in    Gradient Boosting Trees) are logged using log_metric API.     
    #Can be called at every epoch or every step in the training. This is logged to a parquet file and committed at the \n# commit stage.\n\n#Inside training loop\nwhile True: \n     cmf.log_metric(\"training_metrics\", {\"loss\": loss}) \ncmf.commit_metrics(\"training_metrics\")\n
     
    •  
  •  
    Stage metrics, or final metrics, are logged with the log_execution_metrics   method. These are final metrics of a stage, such as final train or test accuracy.      
    cmf.log_execution_metrics(\"metrics\", {\"avg_prec\": avg_prec, \"roc_auc\": roc_auc})\n
     
    •  
 
Dataslices are intended to be used to track subsets of the data. For instance, this can be used to track and compare accuracies of ML models on these subsets to identify model bias. Data slices are created with  the create_dataslice method. 
dataslice = cmf.create_dataslice(\"slice-a\")\nfor i in range(1, 20, 1):\n    j = random.randrange(100)\n    dataslice.add_data(\"data/raw_data/\"+str(j)+\".xml\")\ndataslice.commit()\n

This class provides methods to log metadata for distributed AI pipelines. The class instance creates an ML metadata store to store the metadata. It creates a driver to store nodes and its relationships to neo4j. The user has to provide the name of the pipeline, that needs to be recorded with CMF. 
cmflib.cmf.Cmf(\n    filepath=\"mlmd\",\n    pipeline_name=\"test_pipeline\",\n    custom_properties={\"owner\": \"user_a\"},\n    graph=False\n)\n
 Args:     filepath: Path  to the sqlite file to store the metadata     pipeline_name: Name to uniquely identify the pipeline.     Note that name is the unique identifier for a pipeline.     If a pipeline already exist with the same name, the existing pipeline object is reused.     custom_properties: Additional properties of the pipeline that needs to be stored.     graph: If set to true, the libray also stores the relationships in the provided graph database.     The following     variables should be set: neo4j_uri (graph server URI), neo4j_user (user name) and     neo4j_password (user password), e.g.:     
cmf init local --path /home/user/local-storage --git-remote-url https://github.com/XXX/exprepo.git --neo4j-user neo4j --neo4j-password neo4j\n                      --neo4j-uri bolt://localhost:7687\n

CMF Query communicates with the MLMD database and implements basic search and retrieval functionality.
 
This class has been designed to work with the CMF framework. CMF alters names of pipelines, stages and artifacts in various ways. This means that actual names in the MLMD database will be different from those originally provided by users via CMF API. When methods in this class accept name parameters, it is expected that values of these parameters are fully-qualified names of respective entities.
 
Parameters:
 Name Type Description Default filepath str 
Path to the MLMD database file.

Common metadata framework has the following components:
 
     
  • Metadata Library exposes API\u2019s to track the pipeline metadata. It also provides API\u2019s to query    the stored metadata. 
    •  
  • Local Client interacts with the server to pull or push metadata from or to the remote store. 
    •  
  • Central Server interacts with all the remote clients and is responsible to merge the metadata   transferred by the remote client and manage the consolidated metadata.  
    •  
  • Central Repositories hosts the code, data and metadata.
    •  
 
"},{"location":"architecture/components/#metadata-library","title":"Metadata Library","text":"
The API\u2019s and the abstractions provided by the library enables tracking of pipeline metadata. It tracks the stages in  the pipeline, the input and output artifacts at each stage and metrics. The framework allows metrics to be tracked both  at coarse and fine-grained intervals. It could be a stage metrics, which could be captured at the end of a stage or  fine-grained metrics which is tracked per step (epoch) or at regular intervals during the execution of the stage. 
 
The metadata logged through the APIs are written to a backend relational database. The library also provides API\u2019s to  query the metadata stored in the relational database for the users to inspect pipelines.   
 
In addition to explicit tracking through the API\u2019s library also provides, implicit tracking. The implicit tracking  automatically tracks the software version used in the pipelines. The function arguments and function return values can  be automatically tracked by adding metadata tracker class decorators on the functions. 
 
Before writing the metadata to relational database, the metadata operations are journaled in the metadata journal log.  This enables the framework to transfer the local metadata to the central server. 
 
All artifacts are versioned with a data versioning framework (for e.g., DVC). The content hash of the artifacts are  generated and stored along with the user provided metadata. A special artifact metadata file called a \u201c.dvc\u201d file is  created for every artifact (file / folder) which is added to data version management system. The .dvc file contains the content hash of the artifact.  
 
For every new execution, the metadata tracker creates a new branch to track the code. The special metadata file created  for artifacts, the \u201c.dvc\u201d file is also committed to GIT and its commit id is tracked as a metadata information. The artifacts are versioned through the versioning of its metadata file. Whenever there is a change in the artifact,  the metadata file is modified to reflect its current content hash, and the file is tracked as a new version of the metadata file.  
 
The metadata tracker automatically tracks the start commit when the library was initialized and creates separate commit  for each change in the artifact along the experiment. This helps to track the transformations on the artifacts along the different stages in the pipeline. 
"},{"location":"architecture/components/#local-client","title":"Local Client","text":"
The metadata client interacts with the metadata server. It communicates with the server, for synchronization of metadata.  
 
After the experiment is completed, the user invokes the \u201cCmf push\u201d command to push the collected metadata to the remote. This transfers the existing metadata journal to the server.  
 
The metadata from the central repository can be pulled to the local repository, either using the artifacts or using the  project as the identifier or both. 
 
When artifact is used as the identifier, all metadata associated with the artifacts currently present in the branch of  the cloned Git repository is pulled from the central repository to the local repository. The pulled metadata consist of  not only the immediate metadata associated with the artifacts, it contains the metadata of all the artifacts in its  chain of lineage. 
 
When project is used as the identifier, all the metadata associated with the current branch of the pipeline code that  is checked out is pulled to the local repository. 
"},{"location":"architecture/components/#central-server","title":"Central Server","text":"
The central server, exposes REST API\u2019s that can be called from the remote clients. This can help in situations where the connectivity between the core datacenter and the remote client is robust. The remote client calls the API\u2019s exposed by the central server to log the metadata directly to the central metadata repository.  
 
Where the connectivity with the central server is intermittent, the remote clients log the metadata to the local  repository. The journaled metadata is pushed by the remote client to the central server. The central server, will  replay the journal and merge the incoming metadata with the metadata already existing in the central repository. The  ability to accurately identify the artifacts anywhere using their content hash, makes this merge robust.

Central metadata repository holds the metadata pushed from the distributed sites. It holds metadata about all the  different pipelines that was tracked using the common metadata tracker.  The consolidated view of the metadata stored  in the central repository, helps the users to learn across various stages in the pipeline executed at different  locations. Using the query layer that is pointed to the central repository, the users gets the global view of the  metadata which provides them with a deeper understanding of the pipelines and its metadata.  The metadata helps to  understand nonobvious results like performance of a dataset with respect to other datasets, Performance of a particular pipeline with respect to other pipelines etc.

Interactions in data pipelines can be complex. The Different stages in the pipeline, (which may not be next to each  other) may have to interact to produce or transform artifacts. As the artifacts navigates and undergo transformations  through this pipeline, it can take a complicated path, which might also involve bidirectional movement across these  stages. Also, there could be dependencies between the multiple stages, where the metrics produced by a stage could influence the metrics at a subsequent stage.  It is important to track the metadata across a pipeline to provide features like,  lineage tracking, provenance and reproducibility.  
 
The tracking of metadata through these complex pipelines have multiple challenges, some of them being,  
 
     
  • Each stage in the pipeline could be executed in a different datacenter or an edge site having intermittent connection    to the core datacenter.   
    •  
  • Each stage in the pipeline could be possibly managed by different teams.  
    •  
  • The artifacts (input or output) needs to be uniquely identified across different sites and across multiple pipelines. 
    •  
 
Common metadata framework (CMF) addresses the problems associated with tracking of pipeline metadata from distributed  sites and tracks code, data and metadata together for end-to-end traceability.   
 
The framework automatically tracks the code version as one of the metadata for an execution. Additionally, the data  artifacts are also versioned automatically using a data versioning framework (like DVC) and the metadata regarding the data version is stored along with the code. The framework stores the Git commit id of the metadata file associated with  the artifact and content hash of the artifact as metadata. The framework provides API\u2019s to track the hyperparameters and other metadata of pipelines.  Therefore, from the metadata stored, users can zero in on the hyperparameters, code  version and the artifact version used for the experiment. 
 
Identifying the artifacts by content hash allows the framework, to uniquely identify an artifact anywhere in the  distributed sites. This enables the metadata from the distributed sites to be precisely merged to a central repository, thereby providing a single global metadata from the distributed sites.   
 
On this backbone, we build the Git like experience for metadata, enabling users to push their local metadata to the  remote repository, where it is merged to create the global metadata and pull metadata from the global metadata to the  local, to create a local view, which would contain only the metadata of interest. 
 
The framework can be used to track various types of pipelines such as data pipelines or AI pipelines.

Common metadata framework (cmf) has the following components:
 
     
  • Metadata Library exposes API\u2019s to track the pipeline metadata. It also provides API\u2019s to query the stored metadata. 
    •  
  • cmf-client interacts with the server to pull or push metadata from or to the cmf-server.
    •  
  • cmf-server with GUI interacts with all the remote clients and is responsible to merge the metadata transferred by the cmf-client and manage the consolidated metadata. GUI renders metadata for simplified tracking. 
    •  
  • Central Artifact Repositories hosts the code and data.

Before setting up, obtain AWS temporary security credentials using the AWS Security Token Service (STS). These credentials are short-term and can last from minutes to hours. They are dynamically generated and provided to trusted users upon request, and expire after use. Users with appropriate permissions can request new credentials before or upon expiration. For further information, refer to the  Temporary security credentials in IAM page.
 
To retrieve temporary security credentials using multi-factor authentication (MFA) for an IAM user, you can use the below command.

Object storage is an abstraction layer above the file system and helps to work with data using API. MinIO is the fastest way to start working with object storage. It is compatible with S3, easy to deploy, manage locally, and upscale if needed.
 
Follow the below mentioned steps to set up a MinIO server:
 
     
  1.  
    Copy contents of the example-get-started directory to a separate directory outside the cmf repository.
     
    2.  
  2.  
    Check whether cmf is initialized.    
    cmf init show\n
        If cmf is not initialized, the following message will appear on the screen.    
    'cmf' is not configured.\nExecute the 'cmf init' command.\n
     
    3.  
  3.  
    Execute the following command to initialize the MinIO S3 bucket as a CMF artifact repository.     
    cmf init minioS3 --url s3://dvc-art --endpoint-url http://x.x.x.x:9000 --access-key-id minioadmin --secret-key minioadmin --git-remote-url https://github.com/user/experiment-repo.git --cmf-server-url http://x.x.x.x:8080  --neo4j-user neo4j --neo4j-password password --neo4j-uri bolt://localhost:7687\n
     
    4.  
 
Here, \"dvc-art\" is provided as an example bucket name. However, users can change it as needed, if the user chooses to change it, they will need to update the Dockerfile for minioS3 accordingly.
 
     
  1.  
    Execute cmf init show to check the CMF configuration. The sample output looks as follows:    
    remote.minio.url=s3://bucket-name\nremote.minio.endpointurl=http://localhost:9000\nremote.minio.access_key_id=minioadmin\nremote.minio.secret_access_key=minioadmin\ncore.remote=minio\n
     
    2.  
  2.  
    Build a MinIO server using a Docker container. docker-compose.yml available in example-get-started directory provides two services: minio and aws-cli.    User will initialise the repository with bucket name, storage URL, and credentials to access MinIO.
     
    3.  
  3. Execute the following command to start the docker container. MYIP variable is the IP address of the machine on which you are executing the following command. Following command requires root privileges.    
    MYIP= XX.XX.XXX.XXX docker-compose up\n
        or    
    MYIP= XX.XX.XXX.XXX docker compose up\n
        After executing the above command, following messages confirm that MinIO is up and running. 
    Also you can adjust $MYIP in examples/example-get-started/docker-compose.yml to reflect the server IP and run the docker compose command without specifying 
     
    4.  
  4.  
    Login into remote.minio.endpointurl (in the above example - http://localhost:9000) using access-key and secret-key mentioned in cmf configuration.
     
    5.  
  5.  
    Following image is an example snapshot of the MinIO server with bucket named 'dvc-art'.

SSH (Secure Shell) remote storage refers to using the SSH protocol to securely access and manage files and data on a remote server or storage system over a network. SSH is a cryptographic network protocol that allows secure communication and data transfer between a local computer and a remote server.
 
Proceed with the following steps to set up a SSH Remote Repository:
 
     
  1. Get started with initializing project directory with SSH repo.                                       
    2.  
  2.  
    Check whether cmf is initialized in your project directory with following command.    
    cmf init show\n
        If cmf is not initialized, the following message will appear on the screen.    
    'cmf' is not configured.\nExecute the 'cmf init' command.\n
     
    3.  
  3.  
    Execute the following command to initialize the SSH remote storage as a CMF artifact repository.     
    cmf init sshremote --path ssh://127.0.0.1/home/user/ssh-storage --user XXXXX --port 22 --password example@123 --git-remote-url https://github.com/user/experiment-repo.git --cmf-server-url http://127.0.0.1:80 \n

Common Metadata Ontology (CMO) is proposed to integrate and aggregate the pipeline metadata from various sources such as Papers-with-code, OpenML and Huggingface. CMF's data model is a manifestation of CMO which is specifically designed to capture the pipeline-centric metadata of AI pipelines. It consists of nodes to represent a pipeline, components of a pipeline (stages), relationships to capture interaction among pipeline entities and properties. CMO offers interoperability of diverse metadata, search and recommendation with reasoning capabilities. CMO offers flexibility to incorporate various executions implemented for each stage such as dataset preprocessing, feature engineering, training (including HPO), testing and evaluation. This enables robust search capabilities to identify the best execution path for a given pipeline. Additionally, CMO also facilitates the inclusion of additional semantic and statistical properties to enhance the richness and comprehensiveness of the metadata associated with them. The overview of CMO can be found below.

This example depends on the following packages: git. We also recommend installing  anaconda to manage python virtual environments. This example was tested in the following environments: 
 
     
  • Ubuntu-22.04 with python-3.10
    •  
 
This example demonstrates how CMF tracks a metadata associated with executions of various machine learning (ML)  pipelines. ML pipelines differ from other pipelines (e.g., data Extract-Transform-Load pipelines) by the presence of ML steps, such as training and testing ML models. More comprehensive ML pipelines may include steps such as deploying a trained model and tracking its inference parameters (such as response latency, memory consumption etc.). This example,  located here implements a simple pipeline consisting of four steps:
 
     
  • The parse step splits   the raw data into    train and test raw datasets for training and testing a machine learning model. This step registers one   input artifact (raw dataset) and two output artifacts (train and test datasets). 
    •  
  • The featurize   step creates two machine learning splits - train and test splits - that will be used by an ML training algorithm to   train ML models. This step registers two input artifacts (raw train and test datasets) and two output artifacts (   train and test ML datasets). 
    •  
  • The next train step   trains an ML model (random forest classifier). It registers one input artifact (train ML dataset) and one   output artifact (trained ML model).
    •  
  • The fourth test step   tests the ML model trained in the third train step. This step registers two input artifacts (ML model and test   dataset) and one output artifact (performance metrics).
    •  
  • The last query step   is a demonstration that shows how pipeline metadata can be retrieved from CMF. It will print metadata associated with   all executions of the above steps. This means that if you rerun the pipeline again, the output will include not only   metadata associated with the last run, but also metadata associated with all previous runs.

To execute the example pipeline, run the  test_script.sh  file (before that, study the contents of that file). Basically, that script will run a sequence of steps common for a typical machine learning project - getting raw data, converting it into machine learning train/test splits, training and testing a model. The execution of these steps (and parent pipeline) will be recorded by the CMF. 
# Run the example pipeline\nsh ./test_script.sh\n
 
This script will run the pipeline and will store its metadata in a sqlite file named mlmd. Verify that all stages are  done using git log command. You should see commits corresponding to the artifacts that were created.
 
Under normal conditions, the next steps would be to: (1) execute the cmf artifact push command to push the artifacts to the central artifact repository and (2) execute the cmf metadata push command to track the metadata of the generated artifacts on a common cmf server.
