My review is below. It's basically editorial comments.


Alice' => Alice's

Section 1:

SPARQL 1.1 is a set of specifications that provide languages and protocols to query and manipulate RDF [knowledge => should this be data?] on the Web or in an RDF store.

SPARQL1.1 now [allow thee => allows three] alternative popular formats to exchange answers to SPARQL queries

SPARQL 1.1 Federated Query - [This specification => A specification defining] an extension of SPARQL 1.1 Query [Language] for executing queries distributed over different SPARQL endpoints.

SPARQL 1.1 Service Description - [This document defines => A specification defining] a method for discovering and a vocabulary for describing SPARQL services.

Section 1.1:

In the following, we illustrate the use of SPARQL's languages, protocols, and related specifications [by some => with a] small example.

Section 2:

For instance, one can ask[,] using a SPARQL SELECT query[,] for the identifiers and names of [Alice' => Alice's] friends

Section 3:

The example results use P and N for variable names but the query used ?person and ?name.

Section 4:

The SPARQL 1.1 Federated Query document describes [and => an] extension of the basic SPARQL 1.1 Query Language to explicitly delegate certain subqueries to different SPARQL endpoints.

For instance, in our example, one [might => may] want to find out identifiers of persons with the same names as [Alice' => Alice's] friends on DBPedia[, you may want to combine => . 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 [in a query => remove] as follows:

Section 6:

Operations are provided to update, create [and, => and] remove RDF graphs in a Graph Store.

the respective syntax used in the WHERE part is derived from the [http://www.w3.org/TR/sparql11-query/  SPARQL1.1 Query Language => SPARQL 1.1 Query Language (http://www.w3.org/TR/sparql11-query/)].

Section 7:

The SPARQL 1.1 Protocol for RDF defines how to transfer SPARQL 1.1 queries and update requests to a SPARQL service via HTTP, [definint => defines] how to map requests to HTTP Get and Post operations and how respective HTTP responses to such requests should look like.

Section 8:

For instance, the following [Given the => remove] HTTP request:

providing details about e.g. the default dataset of the respective [andpoint => endpoint]

Section 9:

provides means to perform certain operations to manage [a] collection of graphs more directly
