Joseph Padfield and Rupert Shepherd, The National Gallery, and Rob Tice, Knowledge Integration How can information be opened up within an organisation? The National Gallery was faced with a series of different systems, all holding data related to the collection - but speaking to each other only intermittently. This issue was solved with the installation of a middleware system to combine and deliver data from these eight different data sources as a seamless whole. Our paper will look at the implications this has had for how we work with our data, and as an organisation. We will also touch upon the benefits of opening information up within our organisation, and some projects that are currently using - or are planning to use - our data, which will be delivered using established, open standards.
