MetaCyc reaction, compound CURIEs don't resolve and pathway prefix missing.

[hrshdhgd]

I'm a little new to this so I may not be explaining the issue properly. For this, I apologize in advance.

Now bioregistry.io/CHEBI:15377 resolves to https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:15377. We could not find an equivalent resolution for metacyc.compound or metacyc.reaction. The prefixes exist in bioregistry but the IDs do not resolve.

Examples =======

Reaction

In Metacyc, the reaction seen here would have a bioregistry based CURIE as metacyc.reaction:1.1.1.198 (1.1.1.198 is actually the EC number, so I don't know if this is correct). When I lookup bioregistry.io/metacyc.reaction:1.1.1.198, it takes me to https://metacyc.org/META/NEW-IMAGE?type=REACTION&object=1.1.1.198 which does not seem correct.

Compound

Here's an example of a compound: https://metacyc.org/compound?orgid=META&id=%2b-5-oxo-1-2-campholide

The problem here is a little different. There is a BioCyc ID (+-5-oxo-1-2-campholide) but no ID that would form a CURIE (metacyc.compound:XXXX). Would you have any possible solution to this?

Pathways

• The prefix metacyc.pathway does not seem to exist in bioregistry. Could we add this?
• An example for a pathway would be: 12DICHLORETHDEG-PWY. Here the pathway ID (1,2-dichloroethane degradation) would not follow our standard CURIE pattern. Any suggestions?

All 3 (reaction, compound and pathways) have BioCyC IDs but then they're not represented as ABCD:1234 format we all prefer.

Hi @hrshdhgd can you please break this up into multiple self-contained issues so we can discuss them independently?
