Shapes Constraint Language (SHACL)

Constraints and validation reports for RDF graphs.

Identity and normative owner

Record: shacl; record authority: Modeling. Normative owner of subject: World Wide Web Consortium (W3C). Resource reference: https://www.w3.org/TR/shacl/ Registration is for discovery, not adoption, endorsement, or transfer of normative ownership.

Editions

  • 2017-07-20: W3C Recommendation (named 2017 publication). Named edition for identification, not a claim that it is the newest edition.

Distributions and references

  • shacl-documentation — documentation, text/html, en. Rights are assessed per distribution in the record. Unassessed rights do not imply permission to redistribute.

Verification scope

  • metadata-observed (2026-09-17): Primary-source page metadata observed; no distribution bytes, legal clearance, current-latest guarantee, or implementation conformance was verified.

Cautions

  • SHACL 1.2 is separately referenced as evolving work; do not silently substitute it for the selected 2017 Recommendation.
  • Engine failure, unavailable inputs, and unsupported constraints must not be reported as conformance.
