Dear RIF working group,


we would like to raise some questions regarding the practical use of 
import clause w.r.t RDF data and OWL ontologies:

1) Which is the minimun set of RDF serialization formats that are 
supposed to be supported by a RIF implementation? In the specification 
SWC[1] we read:

"Several syntaxes have been proposed for the exchange of RDF graphs, the 
normative syntax being RDF/XML [RDF-Syntax]. RIF does not provide a 
format for exchanging RDF graphs; it is assumed that RDF graphs are 
exchanged using RDF/XML, or any other syntax that can be used for 
representing or exchanging RDF graphs."

Note that the test cases[2] use the Turtle syntax.

2) If more than one RDF serialization format are to be supported or 
required, how the RIF implementation can determine the parser to be used 
for each import clause?


Thank you in advance!

Best regards,

CTIC
