Long-term preservation of acousmatic works: Toward a generic model of description

Acousmatic works are defined at INA-GRM as pure recorded music that is without live instrument or electronic interaction. Usually, the archive of those pieces consist on a single final tape and its security copies, nowadays a single digital file. In the framework of the CASPAR project, it appears to us that it is very important to archive more elements (variants, source elements, notes, etc.) to perform intelligibility preservation over the long-term. Our proposal is to archive these elements regarding the life cycle of an acousmatic work. We provide a model to represent such a life cycle. This model is based on a method which starts with files to finally get a description of the life cycle. This method was applied to a well-documented work: the Hans Tutschkupsilas recent piece Distance Liquide. A model was built on the description of this work. It was validated with other acousmatic works. Then, it can be considered as a generic acousmatic model. It currently uses the CIDOC-CRM ontology.
