Hi,
EMF query2 provides support for indexing EObject type and references between EObjects. The "EMF index" project provides support for indexing attributes of EObjects, but only has rudimentary query support.
Are there plans to merge the EMF query2 and EMF index projects? In my opinion, query2 should be able to index attributes, and EMF index needs better query support like in EMF query2!
What can I do, if I need attribute indexes in EMF query2?
Thank you in advance!
Greetings,
André

Hi,
I dream of a world where JDT, PDT, etc. use EMF, so we can merge all indexing/query techniques into one project. Why do we always have to reinvent the stuff?
With EMF as the foundation of Eclipse projects, M2M transformations etc. would be easy to integrate, without discovery steps/MWE workflows etc.
Even the Java Editor might be Xtext based, after the generic part of the JDT Java editor was merged into Xtext.
I think, models drive software development. So why not understand everything we touch with Eclipse as an interconnected EMF based model...
Sorry, if I am somewhat off topic.
Greetings,
André

André,
The Xtext folks worked on an index as did the Query2 folks. There was
some effort a while back into merging the two approaches as part of the
EMF index project, but changes to the Query2 team seems to have stalled
that effort. I.e., EMF Index appears to be going nowhere.

Andr,
Yes, that would be very nice. Many people feel this way. :-)
The MoDisco project has a nice Java model...
