Light weight protocols and open source tools in digital library collections

Exploiting "Light-weight" Protocols and Open Source Tools to Implement Digital Library Collections and Services
Xiaorong Xiang and Eric Lease Morgan This article describes the design and implementation of two digital library collections and services using a number of "light-weight" protocols and open source tools. These protocols and tools include OAI-PMH (Open Archives Initiative-Protocol for Metadata Harvesting), SRU (Search/Retrieve via URL), Perl, MyLibrary, Swish-e, Plucene, ASPELL, and WordNet. More specifically, we describe how these protocols and tools are employed in the Ockham Alerting service and MyLibrary@Ockham. The services are illustrative examples of how the library community can actively contribute to the scholarly communications process by systematically and programmatically collecting, organizing, archiving, and disseminating information freely available on the Internet. Using the same techniques described here, other libraries could expose their own particular content for their specific needs and audiences.
