Service Interaction Visual Model (based on today's telecon discussion)

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!
