SQUIN is based on the Semantic Web Client Library[1]. "The *Sematic Web
Client Library* represents the complete Semantic Web as a single RDF graph.
The library enables applications to query this global graph using SPARQL-
and find(SPO) queries. To answer queries, the library dynamically retrieves
information from the Semantic Web by dereferencing HTTP URIs, by following
rdfs:seeAlso links, and by querying the Sindice <http://sindice.com/> search
engine. The library is written in Java and is based on the Jena framework."

Now just imagine the Semantic Web Client library on your server, next to the
rest of the LAMP stack. Your server is the sparql endpoint for the whole
Semantic Web. No need of querying individual sparql endpoints. This is SQUIN
