Title: The Electronic Cultural Atlas Initiative: Global Access to Cultural Data Using TimeMap Methodology


1
The Electronic Cultural Atlas Initiative Global
Access to Cultural Data Using TimeMap
Methodology
CAA 20000 Ljubljana
  • 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

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  • No problems with out-of-date software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

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

Directions 2000 Real money!
  • Strategic Partnereship with Industry for Research
    and Training (SPIRT) grant
  • US300,000 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/doc
    uments
  • 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 dont 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.au8080/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
