SolrMarc is a utility that reads in MaRC records from a file, extracts information from various fields as specified in an indexing configuration script, and adds that information to a specified Apache Solr index.
SolrMarc provides a rich set of techniques for mapping the tags, fields, and subfields contained in the MARC record to the fields you wish to include in your Solr documents, but it also allows the creation of custom indexing functions if you cannot achieve what you require using the predefined mapping techniques.
SolrMarc comes with an improved version of marc4j that improves handling of UTF-8 characters, is more forgiving of malformed marc data, and can recover from data errors gracefully.
A number of example uses of SolrMarc are included in the examples directory.
GenericBlacklight - used to create a demo index for Blacklight (http://projectblacklight.org)
GenericVuFind - used to create a basic index for VuFind (http://vufind.org)
stanfordVuFind - an example of a richly populated Solr index created for the original Stanford VuFind implementation.
stanfordBlacklight - an example of a richly populated Solr index created for Stanford's Blacklight implementation (http://searchworks.stanford.edu/)
UvaBlacklight - an example of the indexing used for the University of Virginia's Blacklight implementation.
