Below is my review of (SPARQL 1.1 Overview):

http://www.w3.org/2009/sparql/docs/sparql11-overview/Overview.xml 

I only have a few changes, overall the document reads well:

In 1.1 Example:

"With SPARQL 1.1 one can query such graphs, load them into RDF stores and manipulate them in various ways."
=>
"With SPARQL 1.1 one can query such graphs, load them into RDF stores, and manipulate them in various ways."



In 4 SPARQL 1.1 Federated Query:

"This can be done by combining a query for the names of friends with a remote call to the SPARQL endpoint at http://dbpedia.org/sparql finding out the name of <http://dbpedia.org/resource/Snoopy> using the SERVICE keyword as follows:"
=>
"This can be done by combining a query for the names of friends with a remote call to the SPARQL endpoint at http://dbpedia.org/sparql, using the SERVICE keyword to find the name of <http://dbpedia.org/resource/Snoopy> as follows:"



"Here, the first part of the pattern in the WHERE part"
=>
"Here, the first part of the pattern in the WHERE clause



In 5 SPARQL 1.1 Entailment Regimes

"(only an excerpt given)"
=>
"(only an excerpt is given)"



In 7 SPARQL 1.1 Protocol for RDF:

"how to transfer SPARQL 1.1 queries and update requests to a SPARQL service via HTTP"
=>
"how to send SPARQL 1.1 queries and update requests to a SPARQL service via HTTP"



In 9 SPARQL 1.1 Graph Store HTTP Protocol

If the example here is meant to mirror the Update example earlier, then I would suggest:

"the first part of the update request in Section 4 above is a simple insertion of triples into an RDF graph"
=>
"the first part of the update request in Section 4 above is a simple insertion of triples into the default graph"



And the example would need to use the ?default keyword to direct the changes to the default graph:

POST /rdf-graphs/service?default HTTP/1.1
Host: example.org
Content-Type: text/turtle
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
<http://www.example.org/alice#me> foaf:knows [ foaf:name "Dorothy" ] .
