Reference

These pages document signatures, arguments, defaults, and return values by interface. For usage examples and design explanations, see the how-to guides and Explanation.

Interface	Stability	Contents
CLI reference	Stable	Every command and flag of the shifty binary.
Python API reference	Stable	The pyshifty validation, inference, and prepared-validator API.
C++ API reference	Stable	The C++17 static library: dataset, prepared validator, evidence sessions, and the shape-map vocabulary.
Evidence reference	Stable	The evidence data model: sessions, runs, polarity, projections, and serialization.
Shape map reference	Stable	Typed keys, bindings, and terms.
Feature support	Stable	Which parts of SHACL Core and SHACL-AF are implemented, and what happens at the edges.
Repair reference	Experimental	Sessions, templates, holes, plans, deltas, and the validation gate.

Stable means compatibility is intended across minor releases. Experimental APIs may change as their semantics and use cases settle.

The Rust API is documented separately on docs.rs/shifty-engine.
