This demo presents Hyperion, a prototype system that supports data sharing for a network of
independent Peer Relational Database Management Systems (PDBMSs). The nodes of …

Sharing structured data in a P2P network is a challenging problem, especially in the
absence of a mediated schema. The standard practice of answering a consecutively …

RDF (Resource Description Framework) is one of the technologies proposed to realise the
vision of the Semantic Web and it is being increasingly used in distributed Web-based …

Abstract Peer Data Management Systems (PDMSs) are advanced P2P applications in which
each peer represents an autonomous data source making available an exported schema to …

The strong dynamics of peer-to-peer networks, coupled with the diversity of peer
vocabularies, makes query processing in peer database systems a very challenging task. In …

We describe a mechanism based on distributed Event-Condition-Action (ECA) rules that

In many scenarios, a contingent data source may benefit by coordinating with external
heterogeneous sources upon which it depends. The administrator of this contingent source …

The introduction of service-oriented computing has created a more dynamic environment for
the composition of software applications, where processes are affected by events and data …

Service Oriented Architecture (SOA) enables the creation of distributed applications from
