LinkML schema for Workflow RO-Crate profile

[elichad]

Could be Workflow RO-Crate or Process Run Crate - the former I think is slightly simpler, but the latter has a clear table of requirements. I don't think it's worth trying to write a full schema for the base spec at the moment.

Still working on this - I'm targeting Workflow RO-Crate profile as the test cases already exist. This is my main focus for the rest of November

I've done as much as I can on this for now - see the feat/linkml branch and specifically the workflow-ro-crate-linkml/ profile directory which contains the majority of the changes.

The SHACL generator in LinkML is missing a lot of the functionality needed to create the SHACL that we need for RO-Crate profiles. There are enough omissions that I think it will be difficult to make a working LinkML version of any profile right now, not just the WROC profile. This doesn't mean it won't be possible in future with improvements to the SHACL generator - the LinkML team are receptive to contributions.

I've raised relevant issues on the LinkML repo: https://github.com/linkml/linkml/issues?q=is%3Aopen+is%3Aissue+label%3Agenerator-shacl+author%3Aelichad. They will need to be resolved for this development to progress further. I will be putting less time into this from now on as it's become clear that this is going to be a long-term project rather than a short-term one, but I will try to keep things ticking over.
