I may thus be noted that metadata describes the various attributes of a resource that are deemed useful to access, retrieve and manage it. According to the United Kingdom Office of Library Networking the term metadata is normally understood to mean structured data about digital and non-degital resources that can be used to help support a wide range of operations, such as resource description and discovery, management of information resources and their long-term preservation. However,definitions of metadata vary depending on one objectives and perspectives. For example for music rsources usage is the most important determining factor for metadata. Music resources are used for several purposes, for example, for recreational listening,study, rehearsal and performance, and each one of these calls for different presentation layout, physical format or specific details.
