Hi,  
I am sending GET request to IBM Jazz DNG to get RDF+XML representation of a specific DNG module (RM collection).  
Returned information contains all the information about the resource (module) but much of that information is NOT needed ( ones with predicate "oslc\_rm:uses " )  
Is there a way to GET a subset of the resource representation that does not contain specified predicates ?  
Best regards.

You could try using an _oslc.properties_ query parameter on your GET to specify the properties you do want returned. While this is part of the OSLC Core specification, this is an optional feature, and some applications might not support it. I don’t know whether DOORS Next implements this. There isn’t an OSLC defined mechanism for excluding properties.
