RE: [stp-dev] SCA v1.0

Hi Johnson,
 
I would need one short technical discussion with the community on the topic first.

What I currently have is a particular set (the complete one for now) of the SCA XSDs imported as one monolithic EMF model. It is completely ok for me right now but I see problems in the future when somebody decides to define new SCA implementation or binding type. Then if we go with the current approach each extension of the SCA spec/standard will force us to recreate the metamodel (EMF model). I would recommend to discontinue the monolitic approach and define separate metamodels (with some references between them) based on a single XSD from the SCA spec. This would lead to a set of EMF models (15 for now).
It is not a challenge to define 15 EMF models (the XSDs are defined) but I would like to ask whether the community would be comfortable with such an approach.
I would like to discuss that point, make the proper changes if decided, and then to attaching the code to bugzilla entry.
Best regards,
Bogdan

Hi Bogdan,
 
Thanks for your help to updating the core model to SCA1.0.
According to the dev plan from stp pmcc, we are going to integrate other existing components and new contributions
based on the sca core model after Eclipse Europa release (June 2007).
 
Would you please create a patch and attach it to the bug?
Since Adrian is on vacation now. I am glad to apply the patch on behalf of you.
 
Best Regards
 
Johnson

Hi Adrian,
 
I saw you have been assigned to the issue https://bugs.eclipse.org/bugs/show_bug.cgi?id=181693.
Do you have any progress on that? Is it possible for me to help you with this issue?
 
Actually I have the SCA v1.0 metamodel already imported (from XSD) as EMF model and I am using it locally for our SCA design-time implementation.
Do you think it is meaningful to send you what I have for the sca1.0 emf based meta-model?
 
This particular problem is the key point for us to start extending the STP framework. Currently we do not extend (or even re-use on API basis) any STP part but we would like to do so.
(Un)fortunatelly we needed SCA v1.0 for our SCA design-time support for the SCA runtime that we are implementing and I had to create the sca 1.0 metamodel.
Now I would like to have it inside STP and actually start using the entire platform, extend extension points, propose new extension points etc.
 
Best regards,
Bogdan
