SKUA is a project with co-Is Norman Gray (project manager) and Tony Linde of the University of Leicester, funded by JISC from Jan'08 to Jun'09.

From the proposal:

We propose the creation of a semantic infrastructure for astronomy based on the organisation of assertion services with relatively simple interfaces. To date, relatively little work has been done within the Virtual Observatory (VO) on semantic systems development. Our project will provide a service-based semantic infrastructure, with toolkit and SOA API, which will make it easy for many more VO developers to engage with semantic technology, and embed it in their applications. The key benefit of this proposal is that it engages with an existing vibrant development and user community, and builds upon working infrastructure, making it possible to demonstrate and prove both concepts and tools as we develop them. The proposed infrastructure will support tagging by design, allowing us, and our users, to experiment with emergent Web-2.0 approaches to social collaboration. This is an integration project, helping client authors find resources and services, tying together existing technology in a new, semantically enhanced and sustainable, context.
