Use Case: Radio Station Archive Digitization

1. Use Case:Radio Station Archive Digitization Owners: Steven Morris David Smith William Waites Presenter: Ray Denenberg

2. Current Practice

3. Radio stations archive audio programs

4. Radio stations archive audio programs • Often not digitized

5. Radio stations archive audio programs • Often not digitized • Little or inconsistent metadata

6. Radio stations archive audio programs • Often not digitized • Little or inconsistent metadata • Occasional efforts to digitize these programs and create metadata

7. Radio stations archive audio programs • Often not digitized • Little or inconsistent metadata • Occasional efforts to digitize these programs and create metadata • Metadata creation usually ad-hoc

8. Goal

9. indexed and searchable

10. indexed and searchable • cross references to other events • particularly news broadcasts

11. indexed and searchable • cross references to other events • particularly news broadcasts • enable federated searching • Across programs and cross referenced events

12. Scenario

13. Scenario …… ……. at the Radio Mogadishu archives

14. An expert works with an archivist to create and annotate digital archives

15. 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.

16. 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.

17. Application of linked data

18. Exploit the extensibility of RDF

19. Exploit the extensibility of RDF • New predicates can be defined as needed.Examples:

20. Exploit the extensibility of RDF • New predicates can be defined as needed.Examples: • Define a subproperty of dc:identifier for the Radio Mogadishu Archives tape labelling scheme.

21. Exploit the extensibility of RDF • New predicates can be defined as needed.Examples: • Define a subproperty of dc:identifier for the Radio Mogadishu Archives tape labelling scheme. • Annotate a recording with information about the participants: • is it an interview? • Who is the interviewer? • The interviewee? • The station director at the time?

22. Exploit the extensibility of RDF • New predicates can be defined as needed.Examples: • Define a subproperty of dc:identifier for the Radio Mogadishu Archives tape labelling scheme. • Annotate a recording with information about the participants: • is it an interview? • Who is the interviewer? • The interviewee? • The station director at the time? • Create URIs for the people involved.

23. Problems and Limitations

24. Little guidance for creating metadata about audio recordings

25. Little guidance for creating metadata about audio recordings • Where to annotate who did the digitization? Who transcribed the metadata?

26. 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.

27. 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"

28. 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?"
