| [modeling-pmc] Re: JCRManagement Project Pre-Proposal |
Sandro, This looks very interesting but it immediately raises questions about how this relates to other existing projects and particularly how it relates to Apogee, i.e., http://www.eclipse.org/proposals/apogee/ and http://www.eclipse.org/apogee/. I think there need to be discussions with the Apogee folks because Eclipse will not generally allow two projects with overlapping scope to exist. This issue seems to represent a road block and I'm not sure how that can be resolved. I've added the modeling PMC to the mailing list to solicit the opinions of the PMC as a whole as to whether this proposal fits within the scope our the Modeling project. My sense is that, like the Apogee project, it probably belongs in the Eclipse technology project, and that perhaps it should be part of the Apogee project...

Once there is a JCR integration into EMF (and the Eclipse-MDSD world) I personally think this could open a very wide range of possibilities and features for the JCR world and could grow to a very strong community. What do you think, is it possible to integrate the JCR into EMF in the way I planned it (or in an other way)? I'm really looking forward to your opinion! ++ Background Details ++ I think I should tell you a bit more about my motivation for this project. Since some years I'm leading a small project that uses it's own CMS for a web site. In 2004 I was very excited seeing the JSR-170 started because it addressed problems that we have in our project. This is why I dived into this world in various ways (Graffito Committer Emeritus, Jackrabbit Contributor, JCR Browser Project Lead). In this time I've seen some problems coming up like: o there is no "JCR Browser with editing capabilities", o what can I use as basis for my JCR application, o migrating node types is hard in a 24/7 environment and o mapping of JCR types to Java types is not too easy. In 2005 I started to learn about Model Driven Software Development and later I had a chance to evaluate MDSD frameworks and tools for our company. The result was that Eclipse has good frameworks as a basis and oAW has a good set of M2M and M2T tools. With MDSD and Eclipse know how I think the mentioned JCR problems can be solved quite elegant. o The solution for the "JCR Browser with editing capabilities" could be an exemplary EMF tool. o An JCR ecore model, EMF resource implementations and the exemplary EMF tool could serve as a basis for JCR applications. o Migrating node types can be done type safe with M2M transformations. o For the type mapping the EMF tooling could fit quite good. On top of that I think GMF can add very interesting features for the CMS world. I hope that gives you some background to this project.
