Yup! To be clear, Schema.org<http://schema.org/> definitions aren't going to say anything about "mandatory", but we are interested in collecting pointers to application-specific profiles that say "in such and such a context, the following data shape is needed to achieve [some outcome]". If you can write those down in Shex or SHACL format, so much the better :)

Completely agree. We are currently working on some tooling to support the presentation of the specifications in a consistent manner on the web pages. This approach should also allow us to generate ShEx/SHACL.

It is clear that we need a new type for BiologicalEntity, it is not clear to me that Proteins, Genes, and Samples all need to have the same mandatory, recommended, and optional set of properties. Perhaps for new types, we should stick to Schema.org<http://schema.org/> style descriptions and then only introduce MG, CD, and CV in usage profiles (specifications) over these types.

I also think many types should be allowed.  whether it should be mandatory depends on whether it must indicate an exact match, or it could link to a more general type where the exact concept is lacking.

I see that PhysicalThing.additionalType is shown as recommended [1] whereas BiologicalEntity.biologicalType [2] was mandatory.  What is the reason for this change?  I thought that this was one for the most critical properties (since most entity types will not have their own Bioschemas subclass).

I might be wrong but I think the specifications are still work in progress. I am taking your comment as a suggestion for PhysicalEntity. Still, we should take a second look to M/R/O for PhysicalEntity and Record and get to some agreements as a group. I think the point you raised makes sense, additionalType should be mandatory (and it has been modified as such). However, I am wondering if anyone has a case where the biological type cannot be provided. Also, is ONE enough? Should be allowed MANY for that field? And, if we allow many, will sameAs be assumed by applications?
