Add kinship relationships to RO

[cmungall]

@balhoff @mellybelly and I are working with the GA4GH KIN group. They have created an ontology of kinship relations:

I identified a few issues:

There is a positive reception to the idea of housing these in RO. There would need to be some extract function that would extract the kin subset.

One challenge is that RO is species-neutral and focused on biological relationships. KIN is human-centric (perhaps also used for veterinary animals?) and includes a mix of social and biological relationships, e.g. step-sibling of, adopted parent of, as well as encompassing situations like surrogacy.

Possible approaches:

1. House biological relations in RO and map to KIN
2. House all of KIN in RO, and provide method to extract subset relevant for KIN use case

update from @mellybelly - the GA4GH community would like a namespace they control

@cmungall I assume you mean that they don't want the IRIs to have the form RO:xxxxxxx. Right? Does mean we should close this issue?

[cmungall]

No, we still need biological kinship relationships in RO as these are broadly useful. I propose we follow route 1 I outlined above (House biological relations in RO and map to KIN)

Update on this:

• There are still a number of logical issues on the GA4GH kinship ontology (https://github.com/GA4GH-Pedigree-Standard/family_history_terminology/issues/created_by/cmungall)
• we still haven't made any progress on this in RO

We need some kinship relations that are non-human specific for VBO (Vertebrate Breed Ontology).
