Current Practice
Radio stations archive audio programs

Little or inconsistent metadata

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.
Application of linked data

New predicates can be defined as needed.Examples:

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
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?"
