As part of the ReSIST Project [1], we have developed a set of knowledge bases and the infrastructure that surrounds them to support all aspects of the project work and endeavour, using Semantic Web technologies throughout. The system includes more than 30 individual knowledge bases, many containing over 10 million RDF triples, along with knowledge capture utilities, knowledge publishing facilities, and the infrastructure required to enable the interoperation of these resources and other external Linked Data sites. It is thus able to give users a unified view of the system as whole [2], as a Meshup of semantic data, which is similar in character to that provided by Mashups of conventional Web 2.0 sites. We present an overview of the system, and discuss certain aspects in more detail, particularly the components that deal with multiple URI references to the same resources.
