Re: Bioschema specifications repo

Hi all,

Please find attached the current overview for Bioschemas entities.

Main changes:
* PhysicalEntity and Record replace BiologicalEntity so the actual 
instance and the record are kept separated.
* PhysicalEntity acts as a wrapper, the intended type is modelled with 
additonalType from the type Thing. It should point to an ontological 
type, for instance http://semanticscience.org/resource/SIO_010043 for a 
protein.
* additionalType can be used as well in Record; for instance 
http://purl.uniprot.org/core/Protein for a UniProt protein record.
* LabProtocol has been updated accordingly
* There could some further discussion regarding the structuralElement 
proposed for CreativeWork as it could be of general interest.

We are now working on the specification documents and some examples as 
well.

Regards,
