YARRRML is a human readable text-based representation for declarative Linked Data generation rules. It is a subset of YAML, a widely used data serialization language designed to be human-friendly. It can be used to represent R2RML, RML, and SPARQL-Generate rules. This tutorial introduces you to YARRRML by explaining how to generate Linked Data from existing data sources with YARRRML rules. You can use Matey to run this tutorial's examples yourself and in the browser.
