RDF Concepts Proposals

PROPOSAL: Resolve ISSUE-66 by adding xsd:duration, xsd:dayTimeDuration, xsd:yearMonthDuration and xsd:dateTimeStamp to the table of allowed XSD types in RDF Concepts ED Section 5.1 (RDF Semantics has a redundant list of the same types; this also needs to be changed accordingly, or removed in favour of normatively referencing RDF Concepts.)

PROPOSAL: RDF-WG will work on an HTML datatype that would be defined in RDF Concepts.

PROPOSAL: Resolve RDF-ISSUE-86 (GraphIsomorphism): Incompatible definitions of “graph equivalence” between RDF Concepts and RDF Semantics by:

  1. renaming “graph equivalence” to “graph isomorphism” in RDF Concepts, and
  2. adding a sentence in the RDF Semantics section on simple entailment, stating that isomorphic graphs are equivalent under simple entailment?
