MusicDNA (database)
MusicDNA is a file system that consists of an ontology that describes the underlying structure of the events that make up musical history – "who did what, where, and when" together with a set of user interfaces that allow subscribers to view, add and edit entries. MusicDNA is implemented using a specially developed version of Topic Maps. MusicDNA uses "persistent subject identifiers" to refer to subjects or topics and an ontology or "conceptual reference model" to describe the relationships between those subjects. History MusicDNA began life as a website supporting BBC Radio's 18-hour programme, The Unfinished Symphony, and was created by Antony Pitts. This charted the history of Western music during previous millennia. The programme was broadcast from 0600 31 December 1999 to 0005 1 January 2000. The accompanying site used a novel navigational tool which presented each item in the broadcast as an element in a timeline view. In subsequent research Antony Pitts combined the hori ...

A topic map is a standard for the representation and interchange of knowledge, with an emphasis on the findability of information. Topic maps were originally developed in the late 1990s as a way to represent back-of-the-book index structures so that multiple indexes from different sources could be merged. However, the developers quickly realized that with a little additional generalization, they could create a meta-model with potentially far wider application. The ISO/IEC standard is formally known as ISO/IEC 13250:2003. A topic map represents information using * ''topics'', representing any concept, from people, countries, and organizations to software modules, individual files, and events, * ''associations'', representing hypergraph relationships between ''topics'', and * ''occurrences'', representing information resources relevant to a particular ''topic''. Topic maps are similar to concept maps and mind maps in many respects, though only topic maps are ISO standards. Topi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
