Abstract

The fundamental problem the Grid research and development community is seeking to solve is how to coordinate distributed resources amongst a dynamic set of individuals and organizations in order to solve a common collaborative goal. The problem arises through the heterogeneity, distribution and sharing of the resources in different virtual organizations. Interoperability is a main issue for applications to function with the Grid. This talk introduces a matchmaking framework for service discovery in Grid environments based on three selection stages which are context, semantic and registry selection. It provides a better service discovery process by using semantic descriptions stored in ontologies which specify both the Grid services and the application knowledge. The framework permits Grid applications to specify the criteria a service request is matched with and enables interoperability for the matchmaking process.
