Metadata, an ethical issue for librarians. An interview with Vincent Boulet • Transparency is not only about disclosure and accountability, but also about taking a critical approach to one's own professional practices. In recent years, the question of implicit bias in classification has been raised with increasing force in English-speaking countries. For example, the Canadian Federation of Library Associations' Committee on Cataloging Standards and Metadata contributed to the drafting of a code of ethics for cataloging. While the issue raised by this discussion is technical, it is also cultural. How should these issues be understood in the French context? Vincent Boulet offers some potential avenues for analysis to the BBF.
