Notes

• The URIs used for RelationType, e.g. http://purl.org/dc/vocabularies/RelationTypes/v1.0/IsPartOf are subject to change.
• The node arc diagrams indicate a linkage between the three sets of metadata - for example, the [http://www.ariadne.ac.uk/] node appears in all three. However, as written here each set of metadata would be held in a separate RDF file. There is currently no widely agreed mechanism to navigate between such files. (The three RDF files could be combined to form a single file).
• The paper and Web versions are assigned ISSN-based URNs as identifiers (as defined in RFC-2288).
• An RDF description of several issues of Ariadne is available separately (~350K).
