Re: [emf-dev] Status of EMF Query

Hi

EMF query/transaction/validation are pretty much on life support after the final IBM committer stepped down. Some Obeo commiters kindly stepped up to rescue EMFq,EMFt,EMFv from oblivion, merging them as the EMF Services project. I doubt that there is much enthusiasm to do more than keep the builds going. If you are interested in contributing, you probably need to request to become a committer.

wrt EMF Query, I have never understood its purpose. In particular, the EMFq OCL support seems to just add a level of opacity; it seems much easier to specify the OCL query directly. I can only assume that the EMFq support was part of the XML fumbling that motivated the addition EMF delegates and so facilitated the much more ergonomic OCLinEcore support.

NB. EMFq,EMFt,EMFv are nothing to do with QVT for which QVTo and QVTd projects are active.

Regards

Ed Willink

Hi,

I think EMF Query is not active and probably only maintained as far as build errors are concerned (see [1]).

If you are looking for an active alternative for declarative queries over EMF, I would suggest you check out Eclipse VIATRA [2]. I would be very happy to provide you with further details if you are interested or you can just write to the Forums [3].

Hi all,

I am interested in EMF Query and I wonder what is the status of this
project. Its project website says that it has been merged into EMF
Services. The EMF Services website says that it is deprecated without
any further information about its (recommended) replacement. My
questions are:

Is EMF Query project still active/maintained?

What is the (recommended) replacement of EMF Query?

Best
