Subject: Re: [soa-rm-ra] Fwd: DM2 Soa Modeling - SoaML Perspective workingmeeting

Agreed, first things first. However, I think we could use the venerable 
furniture moving situation with participants A and B, and for the sake 
of setting it into a context, let's say A takes the single action of:

A sends an email to B: Hi B, Can you help me move this table Saturday?


Wild Card: the email disappears with no bounce notice. It's possible but 
doesn't help us, so I propose we ignore it for the sake of getting to 
the atomic level of granularity.

B can miss or ignore email, and no Joint Communicative Action occurs. 
(Let's dismiss the philosophical question about whether a negative joint 
action occurred because we can't establish a priori whether B notices 
the email or not, and if B does and ignores it, no one else knows 
either, and it doesn't matter.)

B can answer: Hi A, Sure, and a Joint Communicative Action occurs 
whether the table ever gets moved or not.

B can answer: Hi A, I'm busy Saturday, but I could do it Sunday. How 
does that work for you? and a Joint Communicative Action occurs whether 
the table ever gets moved or not.

B can answer: Hi A. No, and a Communicative Joint Action occurs even if 
the outcome does not lead to a Joint (Physical) Action resulting in the 
intended Real Word Effect.

In any event, before the Joint (Physical) Action can occur, some 
Communicative Joint Action needs to take place and I think this is the 
level of atomic granularity I referred to previously.
