Tutorials

These tutorials introduce validation, structured results, and failure explanations using small examples.

Your first validation installs Shifty, writes a shapes file and a data file by hand, and produces a validation report. It also separates the roles of the shapes graph and the data graph.

Reading validation results in code moves from reading a report to writing code that consumes one: walking violations and their reasons, branching on the constraint that failed rather than on its message, and grouping findings the way your consumer needs them.

Explain a validation result uses the evidence interface to inspect which nodes passed or failed and the derivation behind each result.

If you already know SHACL and just want a specific job done, the how-to guides are shorter and assume more.
