Action Semantics

Theory and Practice of Action Semantics by Peter D. Mosses

Remark: A very good introduction to action semantics, which clearly lets you know what has been done in the past decade, what is going on in this area currently, and what will be focused on in the future. The main idea of action semantics is explained with suitable illustrations.

Action Semantics and ASF+SDF -- System Demonstration by Peter D. Mosses

The Architecture of a UML Virtual Machine by Dirk Riehle, Steven Fraleigh, Dirk Bucka-Lassen, Nosa Omorogbe

Remark: A report on an attempt to execute UML models in a virtual machine. The focus is on the design and implementation of this virtual machine rather than the general semantics of UML, without which, in my opinion, no design or implementation can be universally satisfactory (whether it is a compilor or a virtual machine).
