A question it raises for the JSON(sans -LD) conversion is whether the JSON-LD form is acceptable. I have no in-sight there but it is something to test before going along a partcular spec'ing path. I wasn't thinking that the conversion would necessarily be driven by OWL, leaving that for tools beyond/better than the core spec. It is nice to be aware of the possibility. If there are certain common conversions of ISO 8601 syntax for the date-time, we can include those conversion. This one is drop certain legal URIs chars (":" and "-" timezone other than Z?) My feeling is that a real-world issue is that datetime strings are all too often not valid in the first place (systematically or not) and so the error handling is important. As CSV is a text format, string processing can be done before CSV2RDF conversion. Clean-up is best done at that point a well. Seems like a processing pipeline model is emerging. Andy
