What is RedStore ?

RedStore is a lightweight RDF triplestore written in C using the Redland library.

It has a HTTP interface and supports the following W3C standards:


  • Built-in HTTP server
  • Mac OS X app available
  • Supports a wide range of RDF formats
  • Only runtime dependancy is Redland.
  • Compatible with rdfproc command line tool for offline operations
  • Unit and integration test suite.


redstore [options] [<name>]
   -p <port>       Port number to run HTTP server on (default 8080)
   -b <address>    Bind to specific address (default all)
   -s <type>       Set the graph storage type (default hashes)
   -t <options>    Storage options
   -n              Create a new store / replace old (default no)
   -f <filename>   Input file to load at startup
   -F <format>     Format of the input file (default guess)
   -v              Enable verbose mode
   -q              Enable quiet mode

Start RedStore on port 8080, bound to localhost, using a new sqlite store:

redstore -p 8080 -b localhost -n -s sqlite

Load a URI into the triplestore:

curl --data uri= http://localhost:8080/load

Add a file to the triplestore:

curl -T foaf.rdf 'http://localhost:8080/data/foaf.rdf'

Add a file to the triplestore with full URI specified:

curl -T foaf.rdf 'http://localhost:8080/data/?graph='

Add a file to the triplestore with type specified:

curl -T foaf.ttl -H 'Content-Type: application/x-turtle' 'http://localhost:8080/data/foaf.rdf'

You can delete graphs with in the same manner, using the DELETE HTTP verb:

curl -X DELETE 'http://localhost:8080/data/foaf.rdf'

Query using the SPARQL Query Tool:

sparql-query http://localhost:8080/sparql 'SELECT * WHERE { ?s ?p ?o } LIMIT 10'


The minimum required versions of the Redland RDF Libraries are:


RedStore uses a standard automake build process:

make install
