Re: [stp-dev] SCA Tools, SCA signatures and STP-IM

Hi Vincent

Since you told me about this, I've been very interested in SCA signatures for STP IM.

Indeed, I look up to it, and I think it should also be very useful in integrating JWT with STP IM, especially to achieve the first use case I've described lately on this mailing list, where JWT designs processes using services designed by the SCA editor.

In my opinion it is a good solution, and the fact that it is similar to xpath expressions based on the SCA standard makes it a standard of sort for models dealing with services, therefore it is appropriate to use by other tools dealing yith services as well.

Regards,

Marc

Hi Vincent,
 
Thanks for saving your last email of the evening with such awesome news! this is a terrific idea and it's the missing link to integrate the SCA models in the STP-IM builder. Hurrah!

Hi all.

Last mail of the evening.
The SCA builder recently introduced a new concept in SCA Tools, called "SCA signature".
It is used by the builder as a marker attribute which allows any SCA model holder (the model being based on XML DOM, or EMF, or a GMF diagram) to resolve the element associated with a resource marker.

Another use case of SCA signatures could be in STP-IM (and this is why I'm promoting it on this mailing-list).
More precisely, it could be used by the STP-IM builder to track changes made in an SCA model.
One of the problem this builder had with SCA is that unlike BPMN, it is not possible to define IDs for SCA elements (...).

SCA signatures may be a partial solution.
I described SCA signatures on the wiki [0] and added some lines about how the STP-IM builder could use this mechanism to trace changes among models.

For those of you who are curious.
