Ways of Seeing The Electronic Cultural Atlas
Initiative As A Digital Museum for Cultural Data

The Electronic Cultural Atlas Initiative
  • Creating a Distributed Digital Library of
    Networked Research Projects
  • Developing an Infrastructure for Interoperability
    of Datasets
  • Visualizing Cultural Data from contributors
    around the world working in a range of
    disciplines on a map-based interface

ECAI A Digital Museum of Cultural Data
  • Inviting contributions of datasets
  • Preservation of data
  • Persistent access to data
  • Encouraging the development and enhancement of
  • Supporting research
  • Visualizing data for display

ECAI A Digital Meta-Museum of Cultural Data
  • A collection of projects digitally preserving and
    making available for study a range of cultural

ECAI A Global Collection of Digital Exhibitions
  • Digital collections of art historical materials,
    such as the Huntington Archive of Buddhist and
    related art

What is ECAI?
  • A consortium of over 700 humanities scholars, IT
    researchers and heritage managers from around the
  • A globally distributed museum of interoperable
    spatial data with a time-enabled GIS interface.
  • A coordinating body for selected research and
    development projects intended to enhance ECAIs
    ability to support cultural data sharing.
    Targeted priorities include gazetteers, temporal
    GIS, spatial data in the humanities, digital
    library networking, and electronic publication
  • A publisher of humanities scholarship utilizing
    new technologies
  • An editorial body for reviewing and classifying
    humanities and historical spatial
  • An institution to train and disseminate these
    methodologies to humanities scholars, heritage
    managers, IT researchers and students

ECAI Organizational Structure
  • Technical Teams
  • Collaborative groups of scholars and technicians
    working to define the architecture and tools
    required to develop ECAI.
  • Regional Teams
  • Comprised of scholars whose work concerns a
    particular world area.
  • Regional team editors foster the creation of
    strategic or base data sets such as historical
    boundaries, linguistic maps, gazetteers, or
    satellite imagery for their region.
  • Thematic Teams
  • Thematic teams are comprised of ECAI affiliates
    that share particular thematic interests.
  • Team members may study diverse regions or work in
    different academic fields.

ECAI Technology
  • ECAI relies on two key technologies
  • The ECAI Metadata Clearinghouse
  • TimeMap suite of software A set of tools to
    create and display spatial and temporal data

ECAI Metadata Clearinghouse System
4. See it mapped
METADATA is central to ECAI
  • DESCRIPTIVE metadata
  • FUNCTIONAL metadata

ECAI Metadata Clearinghouse System
  • Standards for resource identification and
  • dc. Dublin Core Descriptive Metadata
  • Search and retrieval
  • ECAI. ECAI Administrative Metadata
  • Record keeping, evaluation, team affiliation
  • TM. TimeMap Functional Metadata
  • Locate and Display in the Time / Place interface
  • Distributed Resources
  • In which the clearinghouse is a catalog of
    distributed resources that are accessed through
    the spatio-temporal browser by users wherever
    they may be. 

ECAI IT Architecture
  • ECAI Metadata Clearinghouse
  • ECAI Archives
  • Local and Distributed Data Servers
  • Project Development Tools
  • Spatio-temporal Search Tools and Browsers
  • ECAI Web site

TimeMap Software Components
  • TimeMap Viewer (TMView, TMV)
  • Integrate local and remote TimeMap datasets
  • Control map cartography
  • Uses metadata to time-enable the map producing
    complex, interactive visualisation of data over
    time and space

TimeMap Software Components
  • TimeMap is actually a set of three key
  • TimeMap Editor (TMEdit, TME)
  • Metadata creation tool used to generate, export
    and import information about datasets.
  • Metadata serves as a reference to dataset content
    and allows a dataset to be displayed in TMView

TimeMap Software Components
  • TimeMap GeoRegistration (TMGeoReg, TMG)
  • Quickly and easily generate geographic coordinate
    information about raster ('bitmap') datasets.
  • Images in both the .jpg and the .sid format can
    be registered in TMGeoReg, which then generates
    metadata for integration into TMEdit.

Resource Linking
  • One of the essential functions of TimeMap is the
    linking of objects on a time-filtered map to
    local or web-based resources.
  • Resources may be web pages, images, video,
    databases, spreadsheets or complete multimedia
