Ontologies Used in our Linked Open Data

For maximum compatability with other linked open data sources we try to use the same ontologies and vocabularies to describe out data as other sites on the web use for simialr data. In some cases, however, it has not been possible to find an already existant ontology that is suitavble for our use and so we have devised our own. These are published here both to understand our data sets and to enable others to use them for their data.
