Peer-to-Peer Infrastructures for Multi-Knowledge Workflows

The general aim of the Multi-Knowledge project is to develop a collaborative environment to allow networks of co-operating medical research centres to create, exchange and manipulate new knowledge from heterogeneous data sources. The Multi-Knowledge service-oriented architecture (MK-SOA) will enable workflow design and execution based on novel operating procedures to manage and combine heterogeneous data and make them easily available for the imputation of study algorithms. In this paper we focus on the peer-to-peer infrastructure we have developed to support the creation of a fully decentralized collaborative environment, in which each party remains autonomous and the interactions between services are seen from a global perspective
