Re: [emf-dev] [modeling-dev] [tmf-dev] [uml2-dev] Mylyn Context Bridge / Request for large models


Hi Vlad et.al!


I don't really understand because in UML you can already create views which will only display relevant UML information coming from large models. Just drag and drop or use a contextual menu in order to select relevant UML elements and it is displayed immediately in a new diagram. 
Did I miss something ? 

Yes -- I'm still getting familiar with the Mylyn approach since I also come from the modeling side of things -- but there is a big difference. In the case you mention, you have to do all the work. In this case, the tool does all of the work for you! Things are naturally not *quite* that simple ;), and that's why we could really use people's input on bugs like this one: https://bugs.eclipse.org/bugs/show_bug.cgi?id=343219

BTW, I was really remiss in neglecting to mention that Benny Muskalla has already done a lot of work and thinking about this project as you'll see in the project discussions. Here are all the relevant bugzillas (this list is evolving):


[Not sure if TMF wants to be on follow-ups?] 


cheers,

Hi Miles,

I was reading your project description:  "In order to bring the productivity benefits of the task-focused interface to engineers using Eclipse-based modeling technologies, Tasktop will create a “Context Bridge” for EMF-based models and diagram editors. The result of this will be a focused mode for diagrams that shows only the elements related to the task-at-hand, dramatically reducing information overload for engineers working on large models"

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 http://wiki.eclipse.org/Mylyn/Modeling_Bridge 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. http://greensopinion.blogspot.com/2008/12/mylyn-context-driven-domain-diagram.html 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.

cheers,

Miles
