How to get the entire artifact data using OSLC

Hi.

I want to get RDM artifacts using OSLC with Lyo. When I start my development I use RDM 6.0.3 without any iFix installed. With this version it was possible to get the entire UML data of an artifact, which means I got all properties defined with Rhapsody.
After updating to iFix006 the UML data is missing when fetching the artifact using OSLC. The only way to get the UML data is to run a query for the artifact with "oslc.select=*". Is there any other way to get the entire artifact data by simply using its resource url?

Thanks for your help.
