This repository was originally forked to provide further filtering customisations to derive the OAI-PMH document list from SOLR in the form of set_filters, record_filters and format_filters (as documented in https://github.com/CottageLabs/blacklight_oai_provider/wiki/Configuring-the-OAI-PMH-service).
Please use the official blacklight oai provider gem: https://github.com/projectblacklight/blacklight_oai_provider for integrating OAI with Blacklight.
if you would like to retain the customisations, they are now available at https://github.com/CottageLabs/projectblacklight_blacklight_oai_provider/tree/customize_oai_provider. See pull request for status.
