dct:creator&contributor are IRIs

[VladimirAlexiev]

Sec 5 says:

dct:creator IRI or xsd:string
dct:contributor IRI or xsd:string

But DCT: http://purl.org/dc/terms/ says

dcterms:creator
    rdfs:range dcterms:Agent ; <<<
    rdfs:comment "An entity primarily responsible for making the resource."@en ;

So I don't think using xsd:string is quite correct. If you want to allow xsd:string, use DC Elements (dc:creator&contributor)

[micheldumontier]

my preference is that people assign IRIs and annotate it with the name of the agent. that way, it can be later linked with orcid or some other identifier.

@AlasdairGray what do you think?

[VladimirAlexiev]

You could split to props and express the preference, eg dct:creator IRI SHOULD The preference is to express creators & contributors as a resource, this way they can be later linked with a resource from another dataset (eg ORCID) dc:creator xsd:string MAY

[AlasdairGray]

My preference is also for an IRI. However, there is no restriction on the datatype of dct:creator and it is often used with just a string. That is why we have the entry in the table in that form.

We discussed this in the telco and decided to limit the values to IRIs (removing xsd:string as an option).

We need to ensure that the sentence is removed from §6.2.5 as well.

The definition in DCTerms is:

dcterms:creator
    a rdf:Property ;
    rdfs:isDefinedBy <http://purl.org/dc/terms/> ;
    rdfs:range dcterms:Agent ;
    rdfs:subPropertyOf <http://purl.org/dc/elements/1.1/creator>, dcterms:contributor ;

Although it's not declared an owl:ObjectProperty, the rdfs:range shows that it is so. Whether some people use it incorrectly is a different question. Your document should not promulgate incorrect usage.
