+Rya Streams is a system that processes SPARQL queries over streams of RDF

+
+There are three basic building blocks that the system depends on:
+
+* **Streams Query** - This is a SPARQL query that is registered wth Rya
Streams.
+ It is associated with a specific Rya instance because that Rya instance
+ determines which Statements the query will evaluate. It has an ID that
+ uniquely identifies it across all of the queries that are managed by the
+ system, whether or not the system should be processing it, and whether
or not
+ the results of the query needs to be inserted back into the Rya instance

+* **Query Change Log** - A list of changes that have been performed to the
+ Streams Queries of a specific Rya Instance. This log contains the
