  • 2. Outline • OAIS Representation Information and Representation Information Networks • Organisation of Existing Representation Information • Structure and Semantics Example • RepInfo Network Example • CASPAR/DCC RepInfo Registry/Repository • CASPAR/DCC Tools for curating RepInfo • CASPAR/DCC RepInfo Tools Training Material
  • 3. OAIS Representation Information and Representation Information Networks
  • 4. Information Model & Representation Information Information Object The Information Model 1+ is key Data Object interpreted using 1+ Representation Information interpreted using Recursion ends at KNOWLEDGEBASE of the DESIGNATED COMMUNITY (this knowledge will change over time and region) Physical Digital Object Object 1+ Bit Sequence
  • 5. Organisation of Existing Representation Information • RepInfo can be any type of object, a PDF document, software, text, xml etc. • In its basic form it is just the existing information about the data. • So curating RepInfo can be viewed as classifying and organising existing information about data. • RepInfo is the only thing that can allow data to be reused. • RepInfo some can be shared and reused.

  • 8. UNESCO Villa Livia Data
  • 9. Villa Livia Data • 3D point clouds (formats: imp, dxf, dwg) • Elevation grids (agr, bt) • 3D meshes (mdl, vrml, v3d) • Textured 3D models (max, pmr, ive, osg) • Satellite data (ers, ecw) • GPS data, maps (txt, apm, shp) • Digital images (targa, jpeg, tiff, png, psd, bmp, gif, dds) Total data size approximately 500 GB
  • 10. UNESCO Villa Livia Data
  • 11. RepInfo Network Example
  • 12. CASPAR/DCC RepInfo Registry/Repository • Allows you to stores and retrieve RepInfo and RepInfo Networks. • Facilitates the sharing and reuse of Repinfo – unique identifiers for RepInfo (CPIDs). • Has an API (software interfaces) to allow you to communicate with it. • Currently implemented with OASIS ebXML Registry software (FreebXML) and JAXR API. • API could be implemented with any registry software. • Web Interface at http://registry.casparpreserves.eu • Registry software and API available in the CASPAR SVN Code Repository: http://developers.casparpreserves.eu:8080/
  • 13. Registry API CASPAR Registry API •SOAP CASPAR Non- •JAVA CASPAR Registry Implementation Registries E.g. PRONOM, API allows applications GDFR •JAXR to talk to many different implementations
  • 14. CASPAR/DCC Tools for curating RepInfo • Java GUI Tool for adding or retrieving RepInfo and RepInfo networks to/from the RepInfo Registry. • It also allows you to visualise RepInfo Networks that exist within the Registry. • Links to applications that allow you to view the RepInfo. • Allows you to retrieve the unique identifier (CPID) for the RepInfo.
  • 15. RepInfo GUI Tool Registry visualisation, searching and display of contents using GUI tool(s)
  • 16. CASPAR/DCC RepInfo Tools Training Material • Video tutorials of using the RepInfo GUI tool • Documentation tutorial for using the RepInfo GUI tool. • Brain Training Game for RepInfo • Video tutorial of using RepInfo creation tools (creating structure and semantics). • Packaging tutorial. • More under construction – Programming guides etc. • All very much under development but a preview for the material is available at: http://twiki.dcc.rl.ac.uk/bin/view/Main/TheStoryPlanAndPresentation • Or we can come to you or you can come to us for a tutorial on our tools. You just need to ask!
