Scenario

Scenario ……

……. at the Radio Mogadishu archives

An expert works with an archivist to create

and annotate digital archives

An expert works with an archivist to create

and annotate digital archives The archivist has archives stored on old tapes, has a

catalog system, but much of the information is simply in his memory.

An expert works with an archivist to create

and annotate digital archives The archivist has archives stored on old tapes, has a

catalog system, but much of the information is simply in his memory.

As the expert creates the digital versions, he annotates them with information from the catalog system, the archivist, and a native (Somali) speaker listening to the tapes.

Annotate a recording with information about the participants: is it an interview? Who is the interviewer? The interviewee? The station director at the time?

Problems and Limitations

Little guidance for creating metadata about audio recordings

Where to annotate who did the digitization? Who transcribed the metadata?

When to create Works, when Manifestations.

No vocabulary to describe the state of source material, e.g. "readable", "partially- readable", "unrecoverable"

Problems and Limitations (Continued)

Confidence/Uncertainly How to preserve information about the transcriber's uncertainty. “Looks like an X but might be Y”. "Is that an 8 or a 3?"
