Definition of metadata for audio recordings in open access digital repositories

Abstract

Introduction: The Library of the School of Public Health/University of São Paulo (FSP/USP) is developing a digital repository for the public health area, and also has an audio collection, called Audioteca, produced by the institution itself. The objective of this study is to define the metadata for audio recordings in open access digital repositories, ensuring that the information attains greater visibility in the extensive internet universe. Method: Audio recordings of the databases Dedalus and LILACS were selected and the metadata used in these databases identified, using respectively MARC21and LILACS methodology formats. Then a minimum metadata scope was established in accordance with of the Dublin Core (DC) schema, which corresponded to the metadata of the earlier formats. Finally, making use of the possibility of adjusting the DC, metadata refinements were created on the basis of a Library of Congress study, as well as some other refinements that met the specific needs of the institution and the Audioteca collection, were introduced, among them being: interviewer, sound editor and technical terms such as audio bits. Results: The result of this study is a specific form for the materials of audio collections, maintaining the compatibility and interoperability of Dublin Core scheme. Conclusion: It is expected that the results concurs to widen the visibility to audio collections which can be transmitted by community and educational radio programs. Such results also fulfill the purpose of promoting the research undertaken by institutions and contribute to the construction of citizenship.
