ISSUE-79: What is the value of a literal whose datatype IRI is not a datatype?

undefined-datatype

What is the value of a literal whose datatype IRI is not a datatype?

State:

CLOSED

Product:

RDF Concepts

Raised by:

Description:

The RDF Concepts spec (in both 2004 and 1.1 versions) does not answer the question what's the value of a literal where the datatype IRI doesn't actually denote a datatype, like <"foo",http://example.com/not-a-datatype>. This is surprising, as there is a section that normatively defines the value of *all other* literals.

There are many possibilities:

(i) the spec leaves it undefined
(ii) that's not a valid RDF graph
(iii) it's a valid RDF graph, but the value, if any, is unknown
(iv) it's a valid RDF graph, and the literal is ill-typed

This should be made explicit.

The status quo is (i). I believe that the model theory says it's (iii).
