History

ARC started in 2004 as a lightweight RDF system for parsing and serializing RDF/XML files. It later evolved into a more complete framework with storage and query functionality. At the beginning of 2011, ARC2 had become one of the world's most-installed RDF libraries. Nevertheless, active code development had to be discontinued due to lack of funds and the inability to efficiently implement the ever-growing stack of RDF specifications.
