Title: OMG Action Semantics Support in EA
Post by: salayande on September 07, 2008, 02:32:14 am

"Action Semantics was added to the UML specification in 2001. Action languages have been around much longer than that in support of the Shlaer-Mellor method. Some existing action languages are Object Action Language(OAL), Shlaer-Mellor Action Language(SMALL), Action Specification Language(ASL), That Action Language(TALL), Starr's Concise Relational Action Language(SCRALL), Platform-independent Action Language (PAL) and PathMATE Action Language (PAL). SCRALL is the only one that is a graphical action language."

Above comment was made on Wkipedia entry for Executable UML.

What support has EA for Action Semantics?

kind regards

Segun

UML 1.5 (and to some extent 1.4.2) included the Action Semantics. This was removed from the metamodel for UML 2.x.

The functions of Action Semantics are now performed by Activity Diagrams and Action Models (to use some of the OMG terminology).

That does not give you (or anyone else) a clear answer, but the stuff is all there if you look hard enough.
