ISSUE-50 (validation): Validation criteria for mapping graphs [R2RML] http://www.w3.org/2001/sw/rdb2rdf/track/issues/50 Raised by: Richard Cyganiak On product: R2RML The spec contains some language here about what kind of extra triples, beyond those that make up the mapping, are allowed in a mapping graph: http://www.w3.org/2001/sw/rdb2rdf/r2rml/#vocabulary For example, it says that mapping graphs SHOULD NOT contain terms in the rr: namespace that are not defined in the document, and it says that mapping graphs MAY contain additional properties such as rdfs:label, rdfs:comment etc even though the spec doesn't explicitly talk about them. This section needs more critical thought. Issues include: - How do we help catching authoring errors? - How do we keep the spec extensible in the future?
