This slide-set aims to introduce the RDF query language SPARQL "from a user's perspective". This presentation predates the introduction of SPARQL 1.1, but may still serve as a good introduction to the query language because it covers many, if not a majority, of basic operations.

- Demonstrates a working knowledge of the forms and uses of SPARQL result sets (SELECT, CONSTRUCT, DESCRIBE, and ASK).
- Differentiates between a Default Graph and a Named Graph, and formulates queries using the GRAPH clause.
- Understands how to combine and filter graph patterns using operators such as UNION, OPTIONAL, FILTER, and MINUS.
- Understands that a SPARQL query matches an RDF graph against a pattern of triples with fixed and variable values.
- Understands the major SPARQL result set modifiers, e.g., to limit or sort results, or to return distinct results only once.
