We use eXist, a native XML database, to store our EAD files, XQuery for querying the eXist database, and XSLT for transforming XML into XHTML. Additionally we use Solr, an open source search service based on the Lucene Java library for searching metadata and full-text. Although the eXist database does include an impressive array of full-text search capabilities Solr has allowed us to experiment with exciting new features such as faceted search.
