Re: [emf-dev] EMF Query2 release

[Anthony Hunter <anthonyh@xxxxxxxxxx>]

Hi Wayne,

A short history lesson is in order:

IBM maintained EMF Query since its inception.
EMF Query is a very small project, so
three years ago we only had one IBM committer on the project Christian
Damus.
Christian Damus left Eclipse and IBM
in March 2009, so EMF Query was left with no committers.
In an effort to increase the number
of committers on the three EMF projects Christian maintained, SAP and IBM
added new committers to the projects and SAP became the project lead
Bernd Kolb became the project lead for
EMF Query.
Over time, the SAP committers contributed
a component EMF Query2 into the EMF Query project. This was meant to be
the 2.0 of EMF Query.

There is no breakdown in our processes,
the committers on EMF Query worked on a new version of EMF Query and calling
it EMF Query2 with a separate name space so to not break existing users.

The only breakdown was getting the two
components to release for Indigo. That is why I suggested separating them.

So I would agree to just make EMF Query
2 a separate project.
 
Cheers...
Anthony

   Re: [emf-dev]
EMF Query2 release

The first step is that you (i.e. the project leadership
and committers) need to determine what the moving forward plan is. 

Frankly, the more that I look at this the more concerned I am that the
EDP is not being followed by the project.

• The EMF website lists EMF Query 2 as if it were already a project.
• EMF Query 2 is distributing a "2.0" despite being incubation (incubating project can only release pre 1.0). For that matter, the 2.0.0 release looks totally official (other than the 'N' in the build number, there's no indication on the downloads page that this is a milestone build).
• AFAIK, EMF Query 2 has not done a single review of any kind.

In short, EMF Query 2 is like a phantom project.

Clearly, there has been a huge breakdown in our processes and I'd like
to understand how it happened so that we can fix it.

I am sensitive to your release concerns, and am willing to help fix this.
But it needs to be fixed.

How do we proceed? Based on previous assertions that EMF Query is still
being used by other folks and will persist for the foreseeable future,
combined with the apparently completely separate development teams, code
base, and release schedule, I'm inclined to recommend that we schedule
an immediate restructuring review in which we can just make EMF Query 2
a separate project. Then EMF Query can decide its own fate.

If this sound right to everybody, we can discuss next steps. We can schedule
this restructuring review for June 23-29; best case scenario is that we
may be able to do a release review two weeks or so later. Assuming all
the pieces fall into place.

Thoughts?

Hi, 

We are getting more questions internally in SAP and in
newsgroups about release of EMF Query2. If we don't make a proper release,
we might loose interest.
Can you please suggest how do you want to take the assessment
?

Hi Anthony, 

How should we do this assessment ? 
Will you give EMF Query2 a try ? Will you have sometime
before indigo release for this ?

The assessment that Anthony is referring to is not an
EDP concept. I
believe that means an assessment of the impact of the change on the
community. This is something that is best done by the project itself. I
am willing to assist, but the project is the ultimate authority on its
community and the impact of change.

Some thoughts...

Strictly speaking, "EMF Query 2" is not currently a separate
entity from
the EDP point of view. Strictly speaking, code from "EMF Query 2"
should
be released using the same version numbering scheme and on single
project-wide schedule. The fact that different build systems are used,
and that different groups of developers--managed via social
convention--is interesting, but not relevant.

Allowing EMF Query 2 to make a separate release using a different
version number while still part of the EMF Query project requires an
exception to the process.

Before I can grant that exception, or permit the creation of a separate
project as part of a restructuring review, I need to better understand
the going forward plan.
