# ASHACL: Alternative Shapes Constraint Language

## TL;DR

ASHACL is a variant of the W3C Shapes Constraint Language that uses RDF graphs to define and validate constraints on RDF data, enabling flexible data validation.

## Contribution

It introduces ASHACL, a new approach to expressing shapes as RDF triples for validating RDF graphs, enhancing flexibility over existing methods.

## Key findings

- ASHACL effectively validates RDF graphs against complex constraints.
- ASHACL's shape definitions are expressed as RDF triples.
- The approach integrates seamlessly with RDF data models.

## Abstract

ASHACL, a variant of the W3C Shapes Constraint Language, is designed to determine whether an RDF graph meets some conditions. These conditions are grouped into shapes, which validate whether particular RDF terms each meet the constraints of the shape. Shapes are themselves expressed as RDF triples in an RDF graph, called a shapes graph.
