This paper proposes a framework for advanced Grid resource discovery and monitoring. In the framework, a service's state data are mapped into ontologies so that service owners may enrich them with semantic and other useful data, while keeping the state data unchanged. The Index Service, based on the OGSA framework, aggregates and maintains the ontology data, and allows users to query the data by using ontology-based query languages. The Index Service also provides a Continual Query mechanism that enables users to submit ontology queries as subscription messages and to be notified when the query results change. This paper also proposes an automatic ontology update mechanism, to keep the ontology data up-to-date.
