RedStore is a self-hosted RDF triplestore written in C using the Redland library. It provides an HTTP interface and built-in server for working with RDF, including SPARQL queries and graph-store operations. Supported standards include SPARQL 1.0 Query, SPARQL 1.1 Protocol for RDF, SPARQL 1.1 Graph Store HTTP Protocol, and SPARQL 1.1 Service Description. RedStore supports a wide range of RDF formats, including Turtle. Storage options include hashes, MySQL, memory, PostgreSQL, SQLite, and Virtuoso, with hashes as the default; a storage module must support contexts. The HTTP interface can load a URI at startup or receive RDF files by HTTP PUT, while rdfproc supports offline operations. The project identifies Redland as its only runtime dependency, with minimum versions of raptor2 2.0.4, rasqal 0.9.27, and redland 1.0.14. Installation uses an automake process involving configure, make, and make install. The project includes unit and integration tests and says a Mac OS X app is available. RedStore is free under GPL version 3 or any later version at the user's option.
