Re: [emf-dev] Status of the EMF Query Component

[Anthony Hunter <anthonyh@xxxxxxxxxx>]

Hi Christian,

Given that IBM has not raised any feature requests on this component or asked for more cool things right now, we are safe to assume that EMF Query does what we want very nicely. Bottom line is that a termination review is not required.

Cheers...
Anthony

Hi, Anthony,

Thanks.  I don't need to know the details of what anyone is doing with this component, but am trying to survey what has essentially been a fairly quiet user base.  I don't want to give the impression that I would pre-suppose any particular outcome.  It's just that I see the set of possible outcomes as being three, of which all have different significance to different stakeholders:  Eclipse likes to have projects that are active, users like to keep projects that are stable and supported, and committers like to have projects to develop.

I have no problem with this component simply releasing as 1.2.x in Galileo (it may just be 1.2.0, at this rate!), but would be happier to be able to add new functionality to it to bring more benefit to users.  Also, once all of the Modeling components are "projectified," I would expect the level of activity to be of greater concern to Eclipse.

Is IBM interested in enhancing this component, doing more cool things with it?  I would be very happy to work with some new contributors.  I'm afraid that I haven't been very good at developing the committer base for this component.

Cheers,

Christian

Hi Christian,

We are getting more information for you, but IBM makes use of EMF Query in its products. So it cannot go away for Galileo. We would be fine with creating a 1.3 version that has no new content, but just confirms from a build and smoke test perspective that it still works and is at the high standard of quality as the other components in Galileo.

I am wondering why EMF Transaction and GMF have a build dependency on EMF Query for the last three years ? (I.e. EMF Query is listed on the dependencies on the download page).

Cheers...

Hi, all,

The EMF project has had, since Callisto days, a Query component providing a Java API with an SQL-ish feel for structured searches in EObject data. Since its 1.0 release, this component has not added any new features except for keeping up with its dependencies: following EMF Core in adopting J2SE 5.0, and adopting new OCL APIs.

It seems to me that this component never did show much "traction" from the user community and I have no plan to initiate any new work for the Galileo release. A summary of Bugzilla activity looks like this:
• Raised/resolved since the Ganymede (1.2) release: 0 / 0
• Raised/resolved since the Europa (1.1) release: 9 / 9
• Raised/resolved since the Callisto (1.0) release: 11 / 12
• Raised/resolved since the initial commit: 11 / 10

Note that a significant number of these bugs were releng-type bugs tagged against the Query component but applying to common/replicated artifacts and processes across the EMF Query/Transaction/Validation components and also MDT OCL.

So, my questions to the community are:
• Do you use the EMF Query component?
• Are you interested in continuing to develop the EMF Query component?
  • I am happy to help contributors to earn committer rights by working with them on their patches.

Your feed-back is very important to determining whether this component will have a 1.3 release in Galileo, whether it should just produce a maintenance release for Galileo, or whether it should proceed to a Termination Review.

Thanks,

Christian
