Next Generation Model Query

Today I gave a talk on the next generation EMF Model Query together with my colleague Christian Mohr. It was well attended and we got some really good feedback.

The EMF Model Query deals with finding EMF model elements. The current version has some limitations, especially with respect to scalability. The basic problem is that you have to pass in the EObjects you’d like to find in your result. This means that you have load all these elements. For large models this is not feasible. Another issue is the missing type safety for your queries. All these things among many others should go away with the new implementation.

The code for the new query is already in the CVS and build will start to show up soon (they are already available on Hudson). Here is a screen-shot to give you an impression of how the syntax looks like.

In one of my next posts I’ll give some more insights, so stay tuned :-)

Modeling Symposium CfP

Since the early beginnings, every Eclipse Summit had a Modeling Symposium. The symposia are meant to be forums for discussion and exchange between committers of the various projects and the community. Following the tradition, also this year’s Eclipse Summit has a Modeling Symposium. It will be organized by Ed Merks and myself. We are currently looking for proposals. A proposal might be a demo you’d like to show or something you really like or dislike about the Eclipse Modeling Project  and you want to discuss it with the other attendees. Or maybe you have an idea for a new project and you’d like to gather feedback? This is also something you might want to submit. You see, the symposium is all about you, the committer, the contributor, the user. Please send your proposal (about one page) via e-mail to Ed and myself. The proposal should contain some information on what you’d like to demo or discuss and why you think it is relevant.

We are looking forward to your proposals.
