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

[Anthony Hunter <anthonyh@xxxxxxxxxx>]

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...
Anthony

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
