The Concept of Web Service Versioning in Provenance

Provenance has become important for assisting scientists in reproducing a scientific experiment. Data provenance allows a scientist to track the origin of data and to view all changes made to it. Service provenance is concerned with keeping track of the origin of a service, including any changes that have been made to it, what data has been derived from it, and how other services have made use of it. Thus, provenance provides the scientist with a more complete understanding of the data and the service that are consumed and produced, and also the process of conducting an experiment. In this paper, we present work on the neglected concept of web service versioning in provenance. We address the key issue of versioning in service provenance. The paper therefore presents two versioning approaches that supports service versioning, with an example case study scenario using DynaSOAr the Dynamic Service Oriented Architecture framework.
