Abstract

The effective use of web services requires that new and more complex web services can be composed of other web services. With such composed web services, or web workflows as they are also called, the issues related to transactional properties are even more important. For example, execution correctness and reliability are needed. In this paper, we represent a meta ontology for transactional web workflows. It extends other related conceptualizations by incorporating transactional properties. Particularly, it supports a transaction model, called adaptive web transaction model. It introduces a variety of methods for a simple web services to be interconnected to a compose web services. Such interconnection methods provide an elegant way for constructing composed web services.
