The formats CSV [RFC4180] (comma separated values) and TSV [IANA-TSV] (tab separated values) provide simple, easy to process formats for the transmission of tabular data. They are supported as input datat formats to many tools, particularly spreadsheets. This document describes their use for expressing SPARQL query results from SELECT queries.

<p>SPARQL is a query language for RDF data on the Semantic Web with formally defined meaning. This document is a simple introduction to the new features of the language, including an explanation of its differences with respect to the previous SPARQL Query Language Recommendation [SPARQL/Query 1.0]. It also presents the requirements that have motivated the design of the main new features, and their rationale from a theoretical and implementation perspective. </p>

<div class="expand_description">
<p>The SPARQL Protocol and RDF Query Language (SPARQL) is a query language
and protocol for RDF. This document specifies the SPARQL Protocol; it
uses WSDL 2.0 to describe a means for conveying SPARQL queries to an
SPARQL query processing service and returning the query results to the
entity that requested them. This protocol was developed by
the W3C SPARQL Working Group, part of the Semantic Web Activity as
described in the activity statement.
