  1. The Electronic Cultural Atlas Initiative (ECAI) University of California, Berkeley Berkeley, CA 94720 Lewis R. Lancaster, Director Michael Buckland, Co-Director

  2. “Ways of Seeing: The Electronic Cultural Atlas Initiative As A Digital Museum for Cultural Data” Caverlee Cary, Associate Director, ECAI David Blundell, National Taiwan University Brian Zottoli, University of Michigan with contributions made by: Jeanette Zerneke, Ruth Mostern, Kim Carl, and Kevin Mickey Phuket, January 23, 2002

  3. 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

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

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

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

  7. What is ECAI? • A consortium of over 700 humanities scholars, IT researchers and heritage managers from around the world • 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 ECAI’s 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 data • An institution to train and disseminate these methodologies to humanities scholars, heritage managers, IT researchers and students

  8. 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.

  9. 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

  10. 1. Enter search criteria 2. Select a dataset 3. View the metadata ECAI Metadata Clearinghouse System 4. See it mapped

  11. METADATA is central to ECAI • DESCRIPTIVE metadata • FUNCTIONAL metadata

  12. ECAI Metadata Clearinghouse System • Standards for resource identification and retrieval • 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. 

  13. 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

  14. 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

  15. TimeMap Software Components TimeMap is actually a set of three key applications. 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

  16. 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.

  17. 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 presentations

  18. ECAI indexes data by • PLACE • TIME

  19. Showing Change Over Time German Shrines 702 - 957 AD German Shrines 963 - 1231 AD German Shrines 1272 - 1570 AD

  20. Components of ECAI Projects • Metadata • Spatial information • Temporal Information • Maps • Internet Accessible Digital Resources • images, text, statistics, sound, and videos • Connections from Maps to Resources • Attribute display and web resource linking • Cartography • Controlling map layer display range, icon color and shape, time range • Documentation

  21. ECAI Project: Austronesian Linguistics • ECAI Affiliated Project: The Austronesian Linguistic Mapping Project • Editor: David Blundell, National Taiwan University • Technical Directors: Eric Yen, Academia Sinica, and Jeanette Zerneke, UC Berkeley

  22. ECAI Training • Two week-long training programs and one introductory workshop have been held for development of ECAI-compatible projects: • November, 2001: Indianapolis, Indiana: A training session for collaborators working with major projects or data collections • September 2001, Berkeley, California: A pilot training session for close collaborators • January 2002, Hue, Vietnam: A workshop conducted by ECAI TimeMap software and Metadata Clearinghouse developer Ian Johnson for representatives of Vietnam cultural heritage site management teams.

  23. ECAI Training in Southeast Asia • Two further training opportunities in Southeast Asia have been proposed for 2002-2003: • Sukhothai, Thailand: A UNESCO collaboration to introduce GIS and ECAI time-enabled GIS viewer TimeMap for use in cultural heritage site management • Siem Reap, Cambodia: A collaboration with APSARA, the Center for Khmer Studies, and the University of California, Berkeley to digitize and geo-reference Southeast Asian inscriptions and rubbings • Hue, Vietnam: A regional workshop for Southeast Asian scholars and specialists, in collaboration with UNESCO

  24. ECAI Project Technology: Brian Zottoli • ECAI Proposed Affiliated Project: The Art and Culture of Champa • Editor: Truong Ky Phuong, former curator of the Danang Museum of Cham art • Technical Director and Content Developer: Brian Zottoli, University of Michigan • Technical Consultant: Lawrence Crissman, Griffith University

  25. ECAI Conferences • Seoul, Korea, May 21-24: “Cultural Heritage and New Technologies” (Sponsors: Ministry of Culture, Korea and Seoul National University) • Shimane, Japan, September 15-18: “Digital Data Sharing for International and Area Studies” conference and ECAI Technical Development Work Sessions (Sponsor: University of Shimane) • Osaka, Japan, September 20-23: PNC Annual Conference and Joint Meetings with the Electronic Cultural Atlas Initiative, Electronic Buddhist Text Initiative, and IPSJ Humanities Computing Group (Sponsors: Pacific Neighborhood Consortium and Osaka City University)

  26. ECAI Southeast Asia Conference • October, 2003: Annual full communitty ECAI meeting at the PNC Annual Conference and Joint Meetings in Bangkok, Thailand, hosted by NECTEC: An opportunity to feature work done by Southeast Asian affiliates and institutions

  27. ECAI welcomes participation from interested individuals and institutions that: • have data to share in a digital environment • would like to create a digital exhibition of cultural materials • technical expertise • wish to explore the use of the ECAI infrastucture in support of their professional activities • would like to participate in upcoming conference programs • would like to host ECAI TimeMap software training programs
