ManifoldCF - Framework for connecting Source Content Repositories
ManifoldCF is an effort to provide an open source framework for connecting source content repositories like Microsoft Sharepoint, EMC Documentum FileNet, LiveLink (OpenText), Patriarch, Meridio (Autonomy), Windows shares
to target repositories or indexes such as Apache Solr, QBase (formerly MetaCarta). It could also retrieve content from file system, JDBC connector, RSS crawler, and web crawler.
ManifoldCF also defines a security model for target repositories that permits them to enforce source-repository security policies.
