ISSUE-51: Handling of ill-typed literals

ill-typed-literals

Handling of ill-typed literals

State:
CLOSED
Product:
R2RML
Raised by:
Richard Cyganiak
Opened on:
2011-07-08
Description:
"aaa"^^xsd:integer is an ill-typed literal. These are not forbidden in the RDF abstract syntax, but of course are not useful and likely to cause downstream problems.

What should an R2RML processor do when a mapping generates such literals? Generate them anyway? Raise a runtime error? Silently not generate the triple?

And would this be done for a certain set of XSD datatypes for which we require support?

As per WG decision [1]:

[[
RESOLUTION: Close ISSUE-51; the spec now demands that “supported RDF types” MUST raise data error, and other types MAY raise data error
]]
