Modeling and Discovering Data Services over SPARQL Services

Data services have almost become a standard way for data publishing and sharing on the web. Lack of well-defined machine readable model hinders its spreading. In this paper, we devote ourselves to modeling and discovery of data services. We use RDF model to describe the data scheme and semantics of the data services. Then we define a simplified SPARQL query to retrieve the satisfactory data services in means of evaluating the query against the RDF models. Finally we implement a prototype based on Jena framework.
