# Thinking Differently About Web Page Preservation

Representatives from Old Dominion University Department of Computer Science, who were joined by Library of Congress program officer Martha Anderson, provided an overview of their work on the Archive Ingest and Handling Test (AIHT), http://www.digitalpreservation.gov/technical/aiht.html, an initiative sponsored by the National Digital Information Infrastructure and Preservation Program. http://www.digitalpreservation.gov/index.html The AIHT was designed to test the feasibility of transferring digital archives from one institution to another. During the course of the AIHT, Old Dominion developed a number of alternative models for the preservation of Web pages that the Library has developed into full research projects. Old Dominion has developed a tool called "Warrick" that aggregates the byproduct of search engines and crawlers for Web page preservation. The tool crawls the caches of Google, Yahoo! and other search portals to reconstruct entire Web sites that have been lost. A second project enlists the Apache Web server tool to assist in preparing pages that are "preservation-ready." Old Dominion has developed the "mod_oai" Apache module that uses the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) to assist crawlers in identifying updates and additions in a Web site. The module also provides archive-ready representations of the Web pages encoded in MPEG-21 Digital Item Declaration Language (DIDL).
