Open Harvester Systems 2.3.0 Released

The Public Knowledge Project has released Open Harvester Systems 2.3.0.

Here's an excerpt from the announcement:

This is a major rewrite of numerous parts of the Harvester code, including metadata storage and indexing. It increases indexing flexibility to support plugin-based indexing, including Lucene/SOLR support. It also adds OAI Data Provider support, including the potential to convert between metadata formats (currently from various formats into Dublin Core).
