Aspect-Oriented Web Service Composition: A Petri Net Based Approach
Deivamani Mallayya, Baskaran Ramachandran · 2011
In the various approaches of web service compositions proposed by the researcher, Aspect Oriented Web Service Composition (AOWSC) is the most formal way of composition. Composition is a set of relevant candidate web service, synchronously tied up with each other, delivered to the requestor at run time based on the service request. In par with aspect orientation, the candidate web services are developed as aspects, dynamically selected at run time based on the service request, composed through a weaving mechanism and thus handle composition. The weaving mechanism is the heart of AOWSC, as it specifies the order in which the candidate web service has to be synchronously presented with respect to each other. The paper also projects this formal approach of aspect oriented web service composition by using Petri Net algebra.
