Oral history collections: metadata and access challenges

<p>Our institution is digitizing a collection of 2,000 oral history recordings from the liberation struggle era. We are facing several challenges:</p><ul><li>Transcription in multiple languages (isiZulu, isiXhosa, English, Afrikaans)</li><li>Sensitive content requiring restricted access for some recordings</li><li>Linking recordings to named entities (persons, events, places)</li><li>Preservation of original cassette tapes alongside digital surrogates</li></ul><p>Any recommendations for metadata schema?</p>
