How do I filter RRC OSLC Query by a link ?

Hi Gabriel,
Thanks for the pointer to that article.  I'm using RTC 3.0.1.3, the build basis for the article is 4.  Is this capability in 3.0.1.3 as well? 

There is some useful stuff in there anyway that I can make use of and I'll check I've all the right namespaces.

Another part of this is I'd like to be able to say for example is this requirement implemented by another requirement of a specific type.  I'm not sure I see how you would do this from the example which seems to be saying is it linked to a specific thing rather than more generally linked to a kind of thing.  My only thought is that if I provided the URL of the instanceShape, would that do what I want?

Not convinced that this works with 3.0.1.3, but will give it another go

Thanks for your help
