1. BNSC Agency Report David Giaretta Colorado Springs 16 Jan 2007

2. Funding UK Support for DAI-IPR comes from CASPAR (http://www.casparpreserves.eu) andhttp://www.casparpreserves.eu DCC (http://www.dcc.ac.uk)http://www.dcc.ac.uk

3. The CASPAR Consortium The CASPAR Consortium

4. Areas of interest IPR DAI Certification BoF

5. IPR XFDU and SIP work will be used within CASPAR as a packaging implementation Hope that Registry work should be compatible with CASPAR Registry

6. Certification BOF Needed for CASPAR validation

7. Rep. Info. Use and maintenance

8. Registry for Representation Info The Digital Object could have RepInfo packed with it, as well as CPID Support automated access & processing 1 – User gets data from archive. Data has associated Curation Persistent Identifier (CPID) 2 2 – User unfamiliar with data so requests Rep.Info.using CPID 1 3 3 – User receives Rep.Info – which has its own CPID in case it is not immediately usable

9. Use of RepInfo CPID Structure = CPID Semantics = CPID Rendering s/w = CPID CPID Structure = CPID Semantics = CPID Rendering s/w = CPID External Registry Each “bag of bits” has an associated pointer (CPID) to a Label DCC Label – points to other RepInfo CPID copy

10. CASPAR information flow architecture Rep Info

11. CASPAR architecture

12. DAI PAIMAS and PAIS will form basis of CASPAR ingest implementation

13. Accreditation/Certification for repositories Long-standing demand for ability to measure Trustability of digital repositories Part of OAIS “roadmap” RLG/NARA working group Version 1.0 Audit and Certification Checklist about to be released New open workgroup to produce ISO standard for Audit and Certification See http://mailman.ccsds.org/cgi-bin/mailman/listinfo/moims-rac to join mailing listhttp://mailman.ccsds.org/cgi-bin/mailman/listinfo/moims-rac Over 100 members in mailing list Wiki at http://wiki.digitalrepositoryauditandcertification.orghttp://wiki.digitalrepositoryauditandcertification.org

15. CASPAR Testbeds Three testbeds Cultural: UNESCO Performing Arts: INA, IRCAM Scientific: ESA and CCLRC Complex, multi-source, multifaceted data Many common preservation & evaluation & validation issues Some specific requirements on preservation (technical, delivery, legal) Specific user communities/ Knowledge bases Also test the OAIS model

16. Conclusions Information and Knowledge – needs more than just storing the “bits” Understanding and being able to process the vast amount of unfamiliar data which is available is hard It is expensive Costs must be shared So far the Open Archival Information Systems Reference Model provides conceptual framework Many similarities can be exploited Many subtleties need to be explored Watch this space

17. Backup slides

18. Science: CCLRC example World map of ionosondes

19. Laser facility produces Binary data normally used by proprietary software Describe using EAST data description language Use in generic application (shown here) to display/process Example of use of RepInfo

20. Some Issues Difficult to derive physical quantities from data Can be analysed in multiple ways Raises fundamental questions about Representation Information Common automated method is proprietary Data structure also proprietary Paper documentation - restricted access Provenance and trust

21. ESA example GOME Global Ozone Monitoring Instrument on ERS-2

22. GOME data processing

23. GOME Level 4 product: Integration of GOME, other data and models GOME Level 3 product: Integration of time and space data GOME Level 2 product: Ozone profile at given location

24. Some Issues Provenance and Context of processed data relationship to Representation Information of raw data and Knowledge base of Designated Community

25. UNESCO examples DATA: Scanned documents and maps Aerial and close range photography (Digital photogrammetry) Monument measurements (Laser scanning) Satellite images (Remote sensing and image processing) Multi-scale digital cartography (Geographic information systems (GIS) and CAD) 3D models, virtual tours (Computer visualization) Mandatory Documentation: Identification of property Description of property Justification of inscription State of conservation and factors affecting the property Protection and Management Monitoring Documentation Contact information of responsible authorities Signature on behalf of the State Party(ies) World Heritage List

26. Performing Arts examples Examples: Score MAX/MSP patches Additional instructions Figure 2: Preservation of interactive multimedia performances Motion Analysis and Recognition Motion- Multimedia Mapping Strategy Multimedia Generation GUI (For monitor & control) Motion Capture and Processing Motions 3D motion data Multimedia output Mapping Parameters

27. Some Issues What is Preservation of “performability”? Composer’s intention Authenticity Proprietary software and hardware Copyright Digital Rights Management

28. Shared Infrastructure Registries of Representation Information Persistent Identifier name resolvers DOI? ARK? URL? – none are guaranteed Interfaces – support preservation and interoperability Standards – Preservation Description Information Fixity, Provenance, Reference, Context
