Some bigger culture groups like javanese people from indonesia don't have surnames, so we should not set this field to MUST.

Either use MAY or SHOULD instead.

Sounds reasonable. But how about the first name? Should there be any MUSTs in the person profile other than the ID?

[HLWeil]

Hmm, good question. Probably also cases where an ORCID does suffice. So yeah maybe set it to SHOULD.

[stuzart]

I completely agree about the cultural differences, and shouldn't be a MUST.
Could just replace both with name instead, this is what the draft bioschemas profile recommends: https://bioschemas.org/profiles/Person/0.3-DRAFT

[floWetzels]

Good catch! So should we say name is a MUST, but familyName and givenName are COULD? Or drop them completely?

[stuzart]

I would say keep name as MUST and drop familyName and givenName

[floWetzels]

Ok, do you agree, @HLWeil @Freymaurer ?

[HLWeil]

I agree that this would be the most practictal solution with no further constraints. But as we want to depict the ISA model with this profile, I think we should stick to givenName + familyName, but just loosen the restriction of familyName.

[stuzart]

sounds good to me, as you say we're constrained by the ISA model.
