  1. CAA 20000 Ljubljana The Electronic Cultural Atlas Initiative: Global Access to Cultural Data Using TimeMap Methodology Ian JohnsonArchaeological Computing LaboratoryUniversity of Sydney

  2. Evolution of the TimeMap Project • CAA 1997 • Methodology • Snapshot-transition model • Interface • Time-based SQL queries • Map animations • One-off animations using SGI • Data • Very limited test data

  3. 1998: ECAI The Electronic Cultural Atlas Initiative (ECAI)“A community of scholars with common tools and shared expertise”(Karl Longstreth, China Data Centre, Univ. of Michigan Jan 99) • Emphasis on metadata: • Plan for a centralised index of cultural datasets • TimeMap (connection) metadata • Descriptive metadata based on Dublin Core • Australian working party: Helen Jarvis, Matthew Ciolek, Larry Crissman, Andrew Wilson, Nerida Cross, Ian Johnson • See http://www.ecai.org for detailed description

  4. 1999: ECAI Metadata clearinghouse • SQL server database holds metadata definitions • Definitions can be modified or extended • Definitions are not hard-coded into software • No problems with out-of-date software • Multilingual metadata dc.language Element (from list of elements) ISO639-2b Scheme (from list applicable schemes) eng Value (from list for chosen scheme)

  5. 1999: Metadata clearinghouse (cont.) • Mechanisms for web-based metadata entry • Tight control of elements, schemes and values(pulldown lists, required values etc.) • Forms generated on-the-fly from definitions + data • Default metadata sets to speed data entry • User management and editorial control • Email notification • Editorial rating system

  6. ECAI Structure diagram

  7. 2000: Data preparation toolkit (TMT) • Consists of: • TimeMap metadata wizard • Metadata editor • Clearinghouse update • Data import (MapInfo, Shapefile, Access, ODBC) • Data thinning • Selection of data fields • Data upload to SQL server • Spatial data stored as compressed blobs • No need for spatial data server

  8. 2000: Data preparation toolkit (TMT) • Consists of: • TimeMap metadata wizard • Metadata editor • Clearinghouse update • Data import (MapInfo, Shapefile, Access, ODBC) • Data thinning • Selection of data fields • Data upload to SQL server • Spatial data stored as compressed blobs • No need for spatial data server

  9. TMT meta/data upload

  10. TMView Vsn 1 main screen

  11. TMView map links

  12. Directions 2000: Real money! • Strategic Partnereship with Industry for Research and Training (SPIRT) grant • US$300,000 over 3 years (plus Museum of Sydney resources) • Museum of Sydney • Design & visitor interaction expertise • Historical data • ESRI Inc. • GIS and mapping toolkits (ArcView, MapObjects) • Web delivery tools (ArcIMS, SDE) • NSW State Records office, Sydney City Archives, NSW State Library, Sydney Harbour Authority and others • Historical data, maps, plans, photographs, documents

  13. Directions 2000: Real data! Museum of Sydney Pilot project • Historical resource on the history of Sydney: • stand-alone display in resource centre • CD-ROM based application (Director, TMView, web browser) • Consolidation of resources collected 1997 – 1999 • Substantial new data collection by MOS • 20 selected historical maps (approx. 10 year intervals) • Approx 500 selected archive maps/photos/images/documents • Museum of Sydney • Sydney City archive • NSW State Records Office • State and University libraries • Approx. 25 – 30 period/theme combinations

  14. Directions 2000: Pilot project • Museum of Sydney Pilot installation (June) • Framework in Director • Dual monitor system • Timeline – grid of time (across), themes (down) • TMView projects loaded from timeline • Display of resources on second monitor • Projection of main screen • First build of project this week

  15. Directions 2000: ECAI • Limited release of TimeMap software • Second quarter, ECAI members, TMT + TMView • “Exemplary projects” • London meeting hosted by British Library • Projects to demonstrate the establishment of an ECAI local/regional/thematic atlas • China Atlas • Historic Sydney project • Others to be finalised

  16. Directions 2000: TMView • Three-tier model (only for Internet access) • Database access isolated on server • Reduces distribution size • Simpler client, no database drivers • Simpler to debug • Isolates database access from vagaries of clients • Security • Single authorisation: clients don’t need access to database passwords • Portability • Allows mixed development environment with Java client

  17. TMView directions …2 • Conversion to ESRI MapObjects • Non-technical reasons • SPIRT Partnership • ESRI site licence • Technical reasons • Considerable difficulties with subset generation speed • MapObjects has built-in Filter property on map layers • Opportunity to integrate with ESRI data and Internet map servers

  18. World cultural sites database • URL • www.archaeology.usyd.edu.au:8080/world_sites • Web-based data submission • Password controlled • Search Getty Thesaurus for geographic locations • Availability • Registered with ECAI clearinghouse • Display of maps in TMView • Simple web mapping application when ArcIMS server available

  19. World sites database
