New IRI format for all resources in CCO using opaque local ids

[neilotte]

On August 1st, 2024 the Common Core Governance Board decided to move forward with a new IRI format that will adopt opaque local IDs. The final format, including any namespace change, is still under discussion, but the hope is that this change will be executed in an upcoming 2.0 release.

This decision follows a previous decision from Ron Rudnicki in 2021 to adopt an opaque IRI strategy for CCO, as well as testing by the CCO developers, and multiple years of discussions in collaborative working groups where the consensus position is that opaque identifiers are to be preferred. This has been the long-standing practice of the Open Biomedical and Biological Ontology (OBO) Foundry, which has coordinated the evolution of domain ontologies among independently working groups prior to 2010 into the present day using this approach.
Now that this decision has been reached, there are multiple discussion items, including:

• How best to ease the transition for CCO end users
• Guidance for CCO end users who prefer human readable labels and are concerned about this change
• Creating a test plan for the conversion

This list is not exhaustive. A (long) issue on the issue tracker preserves many of the different related issues and is worth reviewing as we move this into a discussion thread. See: #105
