There seems to be any amount of RDF-format for the OSLC but what I'm looking for is a simple E-R-like view of the OSLC metamodel which shows the concepts and relationships which can be used to understand the organisation and possible queries.

Is there a (graphic) representation of the OSLC metamodel anywhere?

If you are after a simple graphical diagram, you can find UML models under this Lyo-Docs repo. you can find the source .emx files, as well as .png snapshots under the folder "OSLC-V2/images/".

I you are developing OSLC applications, you might want to consider the modelling tool Lyo Designer. There, you can find a graphical model of the OSLC Core and Domain concepts. The models are based on a OSLC-specific modelling language. Lyo Designer allows you define/extend your own models, from which you can generate an OSLC application, based on the Eclipse Lyo SDK.

I here assume you are aware of the java class implementations of the OSLC Core concepts in Eclipse Lyo. There is also an implementation of the domain specifications.

  • Thanks. Why diagrams don't form part of the OSLC spec is baffling.

  • I can agree. I will forward your comment to the committee. docs.oasis-open.org/oslc-core/oslc-core/v3.0/…

  • It would help if the OSLC provided a ticket system so that comments / requests / bugs can be raised against any or the products to improve its quality.

  • @wikitect! OSLC is a specification, so depending on the product you have in mind, there are different reporting systems. What did you have in mind?
