Preferred IRIs for Xref properties

[ariutta]

@egonw and I were discussing preferred IRIs for Xref properties in BridgeDb, and we'd welcome input from other community members on this.

This webservice endpoint http://webservice.bridgedb.org/Human/attributes/En/ENSG00000139618 returns:

Description    BRCA2, DNA repair associated [Source:HGNC Symbol;Acc:HGNC:1101]
Symbol    BRCA2
Type    protein_coding
Chromosome    13

To describe that call, do these IRIs appear correct? description: http://purl.org/dc/terms/description type: http://www.w3.org/1999/02/22-rdf-syntax-ns#type chromosome: http://purl.obolibrary.org/obo/GO_0005694 identifier: http://purl.obolibrary.org/obo/IAO_0000577 symbol: http://semanticscience.org/resource/SIO_000105

Does Symbol refer to name, as in one of these IRIs? https://vocabularies.wikipathways.org/gpml#textlabel http://schema.org/name http://www.biopax.org/release/biopax-level3.owl#name http://www.biopax.org/release/biopax-level3.owl#displayName http://www.biopax.org/release/biopax-level3.owl#standardName

Or is it specific to a gene symbol, as in http://edamontology.org/data_1026 from the EDAM ontology?

Note that http://webservice.bridgedb.org/Human/attributes/Ce/CHEBI%3A29108 returns:

Symbol    calcium
Symbol    Ca(2+)
Symbol    calcium(2+)
Symbol    calcium, doubly charged positive ion
Symbol    Ca
Symbol    Calcium element

and http://webservice.bridgedb.org/Human/attributeSearch/calcium?attrName=Symbol returns:
