JISC

Overview

The SKUA project is a JISC-funded project to prototype a distributed network of semantically aware shared annotated services (in the form of RDF stores). This “semantic layer” will support a cluster of applications which will either directly support users in finding and recovering useful resources, or indirectly support them by supporting user-facing applications. Although the system we build will be specialised to astronomy, and proved by its interaction with, and anticipated embedding within, the Virtual Observatory, the bulk of the semantic knowledge is localised in the RDF store, with the design goal that it could be replaced if desired by the analogous semantic knowledge of a different domain.

Aims and objectives

Develop SKUA infrastructure using Semantic Web technologies, and deliver either a central service or user-installable desktop servers. Validate the approach and APIs by developing new tools or adapting existing ones to add semantic annotation sharing. In particular, we will produce a ‘Spacebook’ application, to support social networking between astronomers.

Project methodology

We will build on Semantic Web technologies. Norman Gray will produce an initial version of the semantic infrastrucutre. Tony Linde will produce the Spacebook application. The developer (to be appointed) will build on both of these, assisting in the Spacebook development and adapting and extending existing applications to take advantage of the SKUA infrastructure.

Anticipated outputs and outcomes

SKUA infrastructure services as a central service or as a network of downloadable desktop servers. Spacebook application. Various extended versions of existing applications.
