Abstract
Abstract. RDF is one of the technologies proposed to realise the vision of the Semantic Web and it is being increasingly used in distributed webbased applications. The use of RDF in applications that require timely notification of metadata changes raises the need for mechanisms for monitoring and processing such changes. Event-Condition-Action (ECA) rules are a natural candidate to fulfill this need. In this paper, we study ECA rules on RDF metadata in P2P environments. We describe a language for defining ECA rules on RDF metadata, including its syntax and execution semantics. We also develop conservative tests for determining when the order of execution of pairs of rules, or instances of the same rule, is immaterial to the final state of the RDF metadata after rule execution terminates. We describe an architecture for supporting such rules in P2P environments, and discuss techniques for relaxing the isolation and atomicity requirements of transactions. 1
