Mylibrary@Ockham is a system for providing access to indexes of OAI-accessible content. It is written in Perl in conjunction with a number of other open source technologies including MySQL, GNU Aspell, and Wordnet. In a nutshell it works by harvesting data from OAI repositories, saving the resulting data to a (Mylibrary) database, indexing the content using Plucene, enhancing the database through a term frequency-inverse document frequency (TF-IDF) technique, providing access to the index via an SRU (Search/Retrieve via URL) server, and enhancing search results by providing alternative spellings and synonyms to query words.

This system was implemented as a part of National Science Foundation grant (DUE-0333601) called OCKHAM Library Network, Integrating the NSDL into Traditional Library Services.
