Add extended_prefix_map

[joeflack4]

Changes

• Add: extended_prefix_map to mondo.sssom.config.yml

---

@souzadevinicius FYI. We're moving from plain, flat, bijective prefix map to "extended prefix maps" which capture such things as prefix and URI prefix synonyms.

Added to mondo.sssom.config.yml

I first was added this to #394 (see comment), but I think this is better as a standalone PR.

I added it within mondo.sssom.config.yml as opposed to a standalone file. I have no idea however if this could have unintended side effects, so another consideration is that I could make a separate file for the EPM entirely and load that instead.

I verified manually that there are no syntax errors by doing yaml.safe_load() and double checking the contents.

URI prefix synonyms

For several namespaces/prefixes, such as HGNC, I've combined what were previously several prefixes in curie_map (e.g. HGNC and HGNC__2, etc) into 1 EPM entry, e.g.:

    uri_prefix_synonyms:
      - 'https://identifiers.org/hgnc:'
      - 'https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:'

Prefix synonyms

Handled these situations as well. oio is the only prefix synonym, which is on oboInOwl.

@twhetzel @matentzn I'm going to merge this one now, as these are fairly simple changes and we have already discussed / reviewed in our last meeting and as part of #394. After merging, I'm going to rebase #394. Of course, if there's any further review you'd like to do, we can do that post-facto, and if you find anything that needs tweaking, I'll be sure to do in a subsequent PR!
