NOTE! This project has been superseded in favor of a different implementation that is more lightweight and supports OAI v1.1 and v2.0. This page remains to support existing users, but if you are a new user, consider using OAIHarvester2 instead.

The OAIHarvester Open Source project is a Java application providing an OAI-PMH v2.0 harvester framework. This framework can be customized to perform arbitrary operations on harvested data by implementing some Java interfaces. Demonstration implementations of these interfaces are included in the application distribution.


This OAI-PMH client application was originally written to support harvesting of OAI-PMH theses and dissertations for the NDLTD union catalog.
