It uses rdflib for RDF handling and integrates owlrl for optional OWL2 RL Profile inference on data before validation. The validator can run standalone via command-line or be imported as a Python module; it supports multiple output formats (human-readable, table, Turtle, XML, JSON-LD, N-Triples, N3) and offers advanced features like meta-SHACL validation, SHACL Rules iteration, and optional Oxigraph backend support.\n\nTypical workflows involve loading a data graph and a shapes graph, optionally applying inference rules, and then validating the data against the constraints. The package returns a conformance boolean, a results graph in RDF, and human-readable validation text. It adheres to the W3C SHACL Recommendation and is designed for semantic web and linked data applications where schema validation and data quality checks are critical.","worth_installing":"Yes. pySHACL is actively maintained, has low install friction, carries a permissive Apache 2.0 license, and is the standard Python implementation of the W3C SHACL specification. Install it if you work with RDF graphs and need constraint validation; it is production-stable and suitable for both command-line and programmatic use."},"id":"pyshacl","links":{"html":"https://skillfed.io/packages/pyshacl","md":"https://skillfed.io/packages/pyshacl.md","pypi":"https://pypi.org/project/pyshacl/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-28","license_spdx":null,"license_treatment":"permissive","name":"pyshacl","python_support":"supports_current","summary":"Python SHACL Validator"},"popularity":{"monthly_downloads":1058329,"position":4426,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.40.1"}
