“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

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 data 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 materials

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 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

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 1. Enter search criteria 2. Select a dataset 3. View the metadata 4. See it mapped

METADATA is central to ECAI DESCRIPTIVE metadata FUNCTIONAL metadata

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.

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 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

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 presentations

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.

ECAI Training in Southeast Asia Two further training opportunities in Southeast Asia have been proposed for : 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
