SPARQL is the query language of the Semantic Web. Almost every Semantic Web or Linked Data application makes substantial use of SPARQL to access RDF data. With SPARQL, you can:

• Query and search RDF data
• Transform data from one RDF vocabulary to another
• Insert, update, and delete RDF data
• Load RDF data from remote URLs
• Perform all of these operations over HTTP

This tutorial will teach you SPARQL from the ground up. We will use real SPARQL queries that can be run, today, on the Web to teach just about the entire SPARQL language. You'll be able to follow along with your laptop during the tutorial and also to run the queries yourself following the session.

SPARQL 1.1 officially became a W3C standard earlier this year, and this tutorial has been expanded from past versions to cover the new features in SPARQL 1.1, including:

• Aggregation
• Subqueries
• Easier negation
• Property paths
• SPARQL Update

No previous experience with SPARQL is expected, though familiarity with the RDF data model is helpful.
