Re: [viatra-dev] Transformation API

["Daniel Varro" <varro@xxxxxxxxxx>]

Hi,

We need to work on setting up the scene
for the Transformation API in a better way.

1) The wiki page should very precisely
state the intended goal and audience of the API. 
Is it intended to be used by tool developers
or a more broader audience?
Do we propose a language or "only"
an API? If the latter, will there be a language 
a transformation language as well at
a later stage? 

(E.g.: Query specifications captured
in the IQ language can be showed to non-programmers,
while the examples using the Transformation
API are restricted to experienced programmers)

2) To what an extent do we plan to reuse
existing Eclipse technologies (e.g. Xtend) ?
Is it intended as an execution framework,
or also as a primary transformation language?

3) What kind of portability is planned
for the Transformation API / Language?
(The language of IQ is portable to graph
models other than EMF with minor adaptations)

4) Naming conventions need to be revised.

The "fireWhilePossible" should
be renamed to "fireAsLongAsPossible" which is a known terminology
at least in the academic community
The "fireAllCurrent" and "fireOne"
should be renamed to in accordance with IQ termionology, so how about "fireForEachMatch"
and "fireOneArbitraryMatch"?

Cheers,
Daniel

Hi,

as promised, I have set up a wiki page that describes the current transformation
API implementation: http://wiki.eclipse.org/VIATRA2/EMF/Transformation_API

The implementation is in an early stage, everything is open to discussion;
the page contains links to both the transformation API implementation and
the TTC2013 example code.

Cheers,
Zoltán
