Abstract

This paper reviews a project to remodel and unify diverse BBC Archive classification schemes, including the large Universal Decimal Classification (UDC) - based classification, Lonclass, as part of the BBC's Digital Media Initiative (DMI). The aims of the remodelling included migrating classification data from legacy systems and using the faceted structure of the classifications as a basis for proto-ontological relationship building. The processes of analysis and development of a methodology to decompose and reassemble the classifications raised such challenges as how to adapt bibliographic classifications for use as digital asset management tools and how to preserve the legacy intellectual property to enable continuing use of taxonomic classification as an access route to multimedia content. These objectives required the sophisticated semantics of the UDC-based classification to be retained during migration to an off-the-shelf taxonomy management product that could be integrated with diverse systems to form the basis of an enterprise-wide framework. The decompositions and reclassification process informed ways of preserving the high precision semantics of bibliographic classifications for use as a foundation for natural language-based retrieval and for translation into ontologically expressive formats, such as Resource Description Framework (RDF).
