Re: [soa-rm-ra] Service Interaction Visual Model (based on today's telecon discussion)

[Ken Laskey <klaskey@mitre.org>]

I just uploaded a modified service interaction model. �I'm trying to tie a bunch of things together that we often talk to separately, especially how it all works with Action.

Upload is at�http://www.oasis-open.org/apps/org/workgroup/soa-rm-ra/download.php/28484/Service_Interaction2.png.

Folks,

Since many of you on the call this morning are security challenged by your corporate firewalls, I'm uploading this to our Kavi site instead.

This visual model is a first attempt to map from the higher level abstract model describing Communicative Action and its relationship to Interaction to a level of abstraction on par with the Realizing SOAs View in which we map these concepts to Message Exchange and Service Interaction, respectively.� This model or a variant of it will need to be included in the Interacting with Services Model section of the RA.� It's imperative that we come to some agreement on this.� Michael has provided some models as well, which you can see on the Kavi site.� They do not yet, however, reflect our discussions/clarifications today with Frank.

Here's how to "read" the visual model...

�

Communicative Action is a specialization of Joint Action.� (Don't know if we need to reflect that here yet again.� Perhaps.)� Communicative Action conveys Action and Event.� Interaction is composed of Communicative Action.� Message Exchange is a specialization of Communicative Action while Service Interaction is a specialization of Interaction.� Service Interaction realizes Message Exchange (or conversely, Message Exchange is realized by Service Interaction).� [The note opens the question to you all on whether or not this association should be a composition or a realization.� (Incidentally, the dashed line with the open arrow head denotes realization in the UML.)]� Message Exchange is composed of one or more Messages.� A Message is composed of Structure and Semantics, which are described in the Information Model.� A Message is a medium of Service Interaction.��A Message also represents (or denotes) Action and Event.

Appreciate your comments!
