Can Graph Transformation Make Aspect Languages for BPEL Redundant?

摘要

The aspect language AO4BPEL has been introduced as a way to modularize cross-cutting concerns in Web service compositions that are specified in BPEL. AO4BPEL can be difficult to understand and to write for non-XML experts. This paper explores if algebraic graph transformation rules can be used to specify BPEL aspects at the modeling level, and make new aspect languages like AO4BPEL redundant. Three AO4BPEL examples, taken from the literature, are used to test the suitability of graph transformation as a means to simulate BPEL aspects.
