[oslc-core] Usage of LD patch format for OSLC

[Steve K Speicher]

(Sending to both OASIS TC and open-services.net Core groups for awareness)

I have updated the document [1] I have started some time ago regarding a 
patch document format and model for use within OSLC Core WG to include the 
recent LD Patch Format [2].  Feel free to weigh in with any additional 
feedback to me.

Jena should be fine.

I have also applied (thanks to your offline help) an update to some
samples I had done for OSLC [1] using the LD Patch format.  Looks as
if would meet our cases.  Will investigate a bit more some possible
improvements.
