[lyo-dev] Problems with provider's RDF output.
|
Hi!
I developed a provider with OSLC4J for OSLC-RM and have some problems with the RDF output of my services.
I can't get the prefix "oslc_rm" working I want to have for http://open-services.net/ns/rm#.
Instead I always get "j.0". I already developed several provider and never had a problem there.
Any idea what I might have forgotten or did anyone run into a similar problem?
See the output below.
I could also provide full source code, but only to selected persons. Some important parts can be found below.
My provider is based on the http://wiki.eclipse.org/Lyo/BuildingOSLC4J#Run_the_Quality_Management_sample_provider
and the more generic approach there to implement resources and services.
Are there any pitfalls? I have e.g. Requirement extends ViFOslcResource extends AbstractResource for other providers I developed only AbstractResource was extended directly.

Any help would be highly appreciated.
Thanks a lot in advance!
