Response to JC3

Dear Jeremy, OWL working group,

This a response to your review of the RIF RDF and OWL compatibility document [1].

The requested change will be implemented.

It has been decided to use Turtle-style shortcut syntax for IRIs in the document; this should address some of your concerns. In addition, we will add an explanation (see [3]) about the correspondence between plain literals with language tags in RDF and constants in the symbol space rif:text in the document; there was not enough support in the working group for adding specific shortcut syntax for strings with language tags.

Best, Jos on behalf of the RIF working group
