Lyo OSLC4j and OSLC 3.0 Spec

Hi Everyone,

I am currently looking into implementing an OSLC provider/adapter. I have a couple of questions regarding OSLC spec versions and OSLC4J 2.4/4.0 libary.

  • Should I implement OSLC 2.0 or 3.0 spec at this point as 3.0 spec is still in final draft status?
  • Can I implement OSLC 3.0 using OSLC4J library?
  • If I want my provider to work with both OSLC 2.0 and 3.0 consumers, what is the recommended implementation strategy for that?

Thanks in advance for your help.

Hi Sean

Welcome to this community.

I’ll start with the second question where I can give the most direct answer. OSLC4J does not yet support OSLC 3.0. We have had some earlier intentions to lift it, but nothing concrete really materialized.
I am also not aware of any similar support for 3.0.

Whether to implement OSLC 2.0 or 3.0? I guess this should really depend on what other OSLC providers/adaptors you are aiming to integrated with. Most OSLC implementations I know of are still based on 2.0. While OSLC 3.0 is backward compatible, you’ll probably be just as fine with OSLC 2.0.

As for implementation strategy to support 2.0 & 3.0, it should be sufficient to implement 3.0, since this is meant to be backward compatible with 2.0. (But then again, until I see 3.0 implementations I don’t know if any actuall proofs of that).
