 #### Web REST endpoint
 
 The War sets up a Web REST endpoint at `http://server/web.rya/loadrdf` that allows POST data to get loaded into the Rdf Store. This short tutorial will use Java code to post data.

 # Overview
 
-Apache Rya is a scalable RDF Store that is built on top of a Columnar Index Store (such as Accumulo). It is implemented as an extension to OpenRdf to provide easy query mechanisms (SPARQL, SERQL, etc) and Rdf data storage (RDF/XML, NTriples, etc).

 Rya stands for RDF y(and) Accumulo.
