Re: [emf-dev] Mylyn Context Bridge / Request for large models

Thanks guys. Yeah, it's too bad that the really serious implementations all end up being proprietary. There just isn't much call for an open source domain mega-models. :) Perhaps there are some public sector or research models out there. EMF target models (UML, SysML, etc..) could also be helpful. Another thought is just to use the MoDisco Java tools or something to reverse engineer a big Java library into .ecore.

The UML metamodel (available in the UML2 project) is also fairly sizeable, although miniscule in comparison to some customer models I've seen in the past (e.g., a gigabyte or more on disk).

Here's a model of the data tracked by the foundation. It's large and unwieldy and subject to change.

And the corresponding Ecore Tools diagram:

Keep in mind that this is my first crack at a relatively large model and so it may not be representative of "good".

Hi all,

I'm going to be working on a context bridge for EMF and graphical editors. This is a Mylyn and Tasktop project but obviously overlaps quite a bit with Modeling efforts.

Please see for more but the basic idea is that you will be able to get task-focussed slices of an EMF or UML model in the same way that Mylyn gives you task contextualized focus for your overall workspace. The idea is to support those larger models that are difficult to grok and work with all at once. See David Green's blog from a couple of years back for more on the basic idea. Cool, huh? There are a lot of challenges involved and I'll be posting on the forums or dev-lists as appropriate to let people know as the functionality gets into place, but I wanted to see if there were other folks out there interested in the approach and who'd like to share ideas or kick the tires. I think Papyrus folks might be particularly interested.

One this I could really use are large public (i.e. no confidentiality issues) EMF / UML models for design targets and demos. Any source or ideas for larger models would be appreciated.
