Available and Reliable Services

Pastrana J. L., Pimentel E., Katrib, M.

ABSTRACT

This paper presents a framework and a tool for reliable and available services composition and coordination based on connectors defined by service client and automatically generated by the COMPOSITOR tool we have developed. Connectors use contracts to express the non-functional requirements and the behavior desired by the client of a service, such as QoS (Quality of Service) features. The connectors generated are self adaptive. The adaptation enactment is based on using an OWL ontology of the server domain which is used to adapt any mismatch when invoking a service at run-time if the server is updated or replaced. This makes services reliable and available.
