Audio Metadata used in the Radio Nacional de España Sound Archive Project
The 20th century Spanish sound history has been preserved in digital format and may be consulted online through intranet. This is a pioneer project in the broadcasting industry around the world finished in December 2002. This archive is considered the most important audio archive in Spanish language in the world. In this paper it is described the metadata used in this project. Radio Nacional de Espana followed the 1997 European Broadcasting Union standard for the interchange of audio files and their broadcasting: the Broadcast Wave Format. The metadata have two different structures depending on the way they were originally created: on an old medium before 1998 or in a digital format after the project started in 1998. Also the voice/word and the different types of music (classical, light, international or Spanish) have different types of metadata. Some examples are shown with the detailed metadata. Successful teamwork was implemented by Radio Nacional de Espana and IBM fulfilling the project on time.
