Technology Facts and Figures: Architecture TSKernel • Coordination Infrastructure based on Super-Peer System • Server, Heavy Client, Light Client • No Client-Server but Consumer-Producer System
Technology Facts and Figures TSKernel TS Kernal Architecture and Layering Conceptual Model of Space and Data
Technology Facts and Figures: Conceptual Models • Triple Space: a virtual unit of the shared middleware • Triple Space URI: the identifier of a Triple Space • Triple Space Domain, e.g. <ts://tsc.deri.at/space/> • RDF Triples: fundamental Semantic Web data model • RDF Graph: a set of “manually” grouped triples • Named Graph: a pair (URI u, RDF Graph g) http://tsc.deri.at/doap.rdf obj sub
Technology Facts and Figures: TS Kernel write, read, take, query, update, subscribe, advertise based on - URIs - Templates (SPARQL, N3QL) - Named Graphs setPermissions, createUser, deleteUser, createRole, deleteRole, addUserToRole based on - Named Graphs - Meta Graph add, remove mediation rules based on - RDF Triples - URIs

Outlook and Conclusion • Triple Space Computing: new communication and coordination paradigm for machine-machine interaction. • TSC project: proof of concept through prototype implementation and use case analysis with Semantic Web service. • Technology: re-arrangement and combination of established Web technology and Shared Object Space middleware. • AS-IS: conceptual and architectural guidelines and implementation plans. • TO-BE: prototype implementation and showcase
