Hi Christian,

I am interested in the status of the EMFT project. I saw the milestones at
http://www.eclipse.org/emft/doc/mq-mt-vf/qtv_project_plan_1_ 1.html, but I
would like to know some more details.
Will the EMFT project (or subprojects) be delivered with Europa? I saw
that MT, MQ and VF are in the scope of the Modeling Project but I could
not find detailed plans for the Modeling Project for Europa either.
What about CDO and Teneo, are there any plans defined?

Could you refer me to some success stories for any of the EMFT
subprojects? I am highly interested in the state in which these projects
are. Whether they are in productive shape or when they will be in
productive shape?
Too many questions but I would like to know also whether there is an
architectural document for the Model Query framework, where could I find
some performance analysis for quering over different kinds of models,
recommendations for usage, optimization tips, etc.

Maybe some of the details are well known but I could not find the info on
eclipse.org.

Thanks in advance.

Best regards,
Bogdan

PS: Please, if there is info published about what I am asking please refer
me to the proper links. Thanks once again.

Bogdan,

Most components of EMFT will be part of Europa. They are listed in the
table on this page.

http://wiki.eclipse.org/index.php/Europa_Simultaneous_Releas e

CDO and Teneo chose not to be part of the Europa release, but I do
believe they will provided releases that will work well with Europa.

CDO and Teneo are still incubating but the Query, Transaction, and
Validation components, along with OCL exited incubation at the end of
the previous release cycle. We're in the process of updating the
website, as required by the EMO, to indicate which components are
incubating, so that should be more clear shortly. The QTV and OCL
components are being used within IBM products and are "definitely
production quality." Teneo appears to get a great deal of traffic on
this newsgroup, so it's apparent that a significant number of people are
using it effectively, and Martin is amazingly good at answering
questions and fixing problems quickly. Eike is going through a redesign
phase with CDO, so I'm sure he would appreciate involvement and
feedback. I'm not aware of any detailed documents on the query
framework, but maybe Christian will know about something I don't...

Hi, Ed, Bogdan,

To follow-up the question of documentation of Query: the only documentation
available is what you see in the on-line help, which includes tutorials and
a guide to the code examples.

On the subject of query performance: the Query framework is built on EMF's
Tree Iterators, which walk the contents of a resource set, resource, or
object from top to bottom. These perform well, and provide features such
as pruning that are surfaced in the Query API, also, to help tune
performance. Other performance characteristics will depend on

- the nature of the query conditions that you write. Obviously, a
condition that walks a resource again will result in poor performance
as it is evaluated on (possibly) every object
- nesting of queries for iterative refinement of the result set, which
may result from re-use of queries and/or conditions as "building
blocks"

No formal performance analysis has been done; the framework really is just a
collection of utilities to simplify the implementation of, and to separate
reusable components of, iterator-based searches.

HTH,

Christian
