Other Input Documents
The documents here have been proposed as documents for the working group or embody proposals for various aspects of SHACL. They are mostly no longer under active consideration by the working group.
Core SHACL Abstract Syntax (
No longer maintained Note, no plans to move forward
Abstract Syntax FPWD
Editor's Draft, currently unmaintained
SHACL (Shapes Constraint Language) Primer
ericP and Holger, OUTDATED
A Primer for SHACL, concentrating on the high-level language, but also giving examples of constraints directly using SPARQL syntax. Largely compatible with all the other proposals.
Core SHACL Semantics
Iovka and ericP
ShEx-like semantics for SHACL Core
SPARQL/SHACL Semantics
ericP
Description of the non-core part of SHACL
A SHACL Specification based on SPARQL
pfps
A Formal Definition of the meaning of SHACL, based on a translation to SPARQL.
Presentation for VF2F
Recursion in RDF Data Shape Languages
Arthur
A well-founded semantics for recursion associated with sh:valueShape
Z Specification for the W3C Editor's Draft Core SHACL Semantics
Arthur
This article provides a formalization of the W3C Draft
Core SHACL Semantics
specification using Z notation. This formalization exercise has identified a number of quality issues in the draft. It has also established that the recursive definitions in the draft are well-founded.
SHACL Vocabulary Reference Editors' Draft
Paper "Linked Data Validation and Quality", Jose Emilio Labra Gayo, European Public Sector Information Report, No. 2015/09, includes a simple example using ShEx and SHACL:
