Re: [soa-rm-ra] Action - Why we have failed...

[Ken Laskey <klaskey@mitre.org>]

This is where Dave was coming from several weeks ago when he said Action (or action) was used inconsistently all over the place.

So does the attempt in my service interaction model to have Singular Action and Joint Action as specialization of a single Action parent help or further muddy the situation?

The more I do archeology on this subtle yet complex concept of "Action" the more I realized we have failed to clearly articulate it properly, at least on two fronts.

First, if we agree that Action is "the application of intent by a participant to achieve a RWE" then where the heck does the Service fit w.r.t.

Second (the point I was trying to make during yesterday's call), Action, again,�is defined to be the application of intent by a [singular] participant to achieve a RWE (emphasis of singular is mine).� However, Joint Action is defined to by "an action involving the efforts of two or more participants to achieve a RWE."� How in the heck can Joint Action be a specialization of Action the way we defined Action ????� It cannot !� If�Action (as we defined it)�applies to�a singular entity, i.e.,�a participant, then how in the heck can�an action by two or more participants be a specialization of the act of a single participant.� This is just nonsense.� And one of the reasons our proposed visual models are failing over and over again.

We NEED TO GET THIS RIGHT and frankly (no pun intended Frank), we are off course, at least in the tar pits of my world.
