The University of Washington recently became the first library in the United States to use RISM metadata for a music manuscript digital collection. RISM or Répertoire International des Sources Musicales is a “multinational, non-profit joint venture which aims for comprehensive documentation of extant musical sources worldwide” The efforts of the RISM community help to make worldwide musical resources more accessible to all.
On a related note, IPTC recently launched the Embedded Metadata Manifesto for digital media content. This manifesto contains many saliant points including the fact that copyright information must never be removed from a media asset and that people working with media need to be aware of the importance of metadata for retrieval.
Go media metadata!
