Do you want a dedicated editor to write it?

Matey is a browser-based application that helps you write YARRRML rules. The corresponding RML rules can be exported for use outside of Matey. Additionally, the rules can be executed in on a sample of the data, which allows users to inspect the generated Linked Data.
