ckanext-dc_view

A CKAN resource view for DC data. The preview includes metadata from the HDF5 attributes and a summary plot (scatter plot of brightness vs. area and image, contour, mask, and fluorescence data for one event). This plugin registers a background job for generating the overview plot after a DC resource has been created.

This extensione implements:

• A default view for RT-DC (mimetype) resources
• A background job that generates the preview image
• A background job that uploads preview images to the S3 object store
• A route that makes the preview image available via "/dataset/{id}/resource/{resource_id}/preview.jpg"
• CLI:
  • add CKAN command run-jobs-dc-view that runs all background jobs for all resources (if not already done)

Installation

pip install ckanext-dc_view

Add this extension to the plugins and defaul_views in ckan.ini:
