Chapter 6. Updating Data with SPARQL

It’s great when you can pull data out of a collection and rearrange and cross-reference it any way you want, but when you can use a standard query language to add data to that collection, and to delete and update its data, you have what you need to build serious full-fledged applications around RDF’s flexible data model. The SPARQL 1.1 Update specification describes the syntax and options for doing this, and although it’s a more recent addition to SPARQL, several implementations already support it. This chapter uses Fuseki, one of the simplest SPARQL Update implementations, to demonstrate the various examples.


Most implementations you find of the SPARQL Update language will be features of triplestores, letting you act on the data in the triplestore. Being essentially a database management program (if not a relational one), a triplestore should let you query the data with the SPARQL query language and manage it with the update language.

In this chapter, we’ll learn about:
