DP9 is an open source gateway service that allows general search engines, (e.g. Google, Inktomi) to index OAI-compliant archives. DP9 does this by providing consistent URLs for repository records, and converting them to OAI queries against the appropriate repository when the URL is requested. This allows search engines to index the "deep Web" contained within OAI compliant repositories.
