Abstract

This paper presents P2P-DIET, an implemented resource sharing system that unifies one-time and continuous query processing in super-peer networks P2P-DIET offers a simple data model for the description of networkresources based on attributes with values of type text and a query language based on concepts from Information Retrieval The focus of this paper is on the main modelling concepts of P2P-DIET (metadata, advertisements and queries), the routing algorithms (inspired by the publish/subscibe system SIENA) and the scalable indexing of resource metadata and queries.
