Re: Protein representation with and without BioChemEntity

Hi,

I'm wondering if we could take it a step further, and instead of 
defining specific properties we could just reuse terms from RO (or else)?

For example, "http://semanticscience.org/resource/is-transcribed-from" 
could be replaced by http://purl.obolibrary.org/obo/RO_0002510, 
"transcribed from", and "isContainedIn" could be 
http://purl.obolibrary.org/obo/RO_0001018, "contained in".

Cheers,
Melanie
