Music tagging type definitions, systems for music representation and retrieval

The paper discusses the general issues surrounding structured music information representation and music information retrieval, and present the result of the UK-JISC funded "proof-of-concept" project: MuTaTeD! (C. Hall and C. Boehm, 2000) (Music Tagging Type Definition) and discuss further development within the UK Library Information Commission funded MuTaTeD'II project (C. Boehm and D. MacLellan, 2000). Work within the two projects MuTaTeD! and MuTaTeD'II, striving towards the design and implementation of an expandable, flexible music information retrieval system with delivery/access services for encoded music, has resulted in involvement in standards development such as MPEG7, to support the needs of developers within music information retrieval research.
