E42 Identifier

[larsgw]

Don’t use E42_Identifier for URIs. So use

<something> crm:P1_is_identified_by <http://example.org/> .

Would this not mean that <http://example.org/> is the URI of the URI itself (instead of the URI of the concept)?

instead of

<something> crm:P1_is_identified_by [
  a crm:E42_Identifier ;  crm:P90_has_value "http://example.org/" ] .

It looks like crm:P90_has_value is only for E54 Dimension.

In RDF (that is unless we dig into reification, RDF* or similar nasty swamps), there is no such thing as a statement about an URI. There are resources and some resources are identified by an URI. Things start to get difficult with URI aliases (possibly expressed with owl:sameAs) but doable if you just replace every alias URI with a preferred URI of the same resource. Anyway, this handling of URIs is outside of the domain of basic RDF.

I'll fix the wrong use of P90!
