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:

* [SPARQL 1.0 Query]
* [SPARQL 1.1 Protocol for RDF]
* [SPARQL 1.1 Graph Store HTTP Protocol]
* [SPARQL 1.1 Service Description]

Features
--------

* 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.

Usage
-----
    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://example.com/file.rdf 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=http://example.com/foaf.rdf'

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'
