Re: [stp-dev] Intermediate Hybrid Model Discussion
|
Thanks Adrian, this should work.
One thing we might do at some point is publish a list of well known
property names so that everyone uses the same property for the same kind
of information. So e.g. the WSDL might be stored in a property called
'Interface' etc.
Cheers,
David

Hi David,
Thanks for the suggestions, they are both very useful. I think that in
the new version of the model (that I just announced on the mailing
list) the contract can be defined using properties, by creating a
particular property definition (if it's an informal document this
might work). Same for the 'metadata' map you mentioned. If the
contract is a service definition, then perhaps our Service component
would suffice as well, if we agree that for each contract, there is a
service element (there is some conceptual overloading here, I know).
For instance, in SCA, a service may have only one interface, so we'd
not run into trouble with the current model.
Let me know if you think that we lack expressivity with the Service
and property elements, perhaps with an example.
Thanks,
Adrian.

Hi Adrian,
Thanks for posting that. This is certainly very useful.
Just a few additional ideas here:
On the meta model, it might be useful to have a Service Contract
associated with the Service, as all types of Services typically have
some sort of a contract or other - I know certain
editors/technologies may not deal with the interface directly, but
its normally there somehow. This could be WSDL, a Java interface, XML
Schema or even a worddoc describing how it's used.
Also, it might be good to add a 'metadata' map to the Service where
arbitrary key-value pairs can be registered. This could be used by
editors to enhance the metamodel with optional extra metadata that
the transformations could use to make the migration from one model to
another smoother / less lossy.
Just my 2c,
David

Hi David, all,
I have created a page that illustrates a sample scenario involving
the meta-model at
http://wiki.eclipse.org/Sample_scenario_involving_the_intermediate_meta-model
It is rather rudimentary and does not cover the entire set of
entities of the meta-model but I believes it captures the essential
functionality (i.e. moving between editors that deal with different
SOA concerns).
I imagine some things might need further clarification, I will
update the page appropriately as questions arise.
best regards,
Adrian.

Hi Adrian,
Do you think you can provide the example as discussed well in time
to consider it with the proposal. It would greatly help my
understanding of the proposed model.
Thanks!

Hi Guys,
To follow-up to Adrian Skehill's email, we had an interesting
discussion [1] regarding the proposed intermediate model to be
used in STP (by editors that want to benefit from facilitated
state transfer). We would like to speed up the conceptual phase
of this model and start its implementation so I am proposing the
date of Friday 31st as the last day to make any changes to it.
This would allow us to move forward quickly and not hold back
developments on components where this will be used such as the
Service Creation component. So please come forward with any
suggestions and additions to it until next Friday.
best regards,
Adrian.
