Next meeting
- Telecon 2015.11.19
Disposal of Raised Issues
PROPOSED: Open ISSUE-111, ISSUE-112
- ISSUE-111: How should the working group address the issues called out in the WG charter?
- ISSUE-112: SHACL uses RDFS properties in ways that violate their intended RDFS meaning
Requirements
Update on SHACL Requirements coverage table
ISSUE-65: nomenclature consistency
PROPOSED: Close ISSUE-65, while not perfect, the recent editorial fixes and rewrites have sufficiently addressed this. Further inconsistencies to be treated incrementally.
- ISSUE-65: Consistency and cohesiveness of nomenclature (e.g., shapes, scopes, and constraints)
- ISSUE-65 Proposal
- Glossary
ISSUE-96: Violation IDs
PROPOSED: Close ISSUE-96, adding an ID to validation results for each constraint type. These should align with the URIs of the templates and node validation functions in the SHACL system vocabulary.
- ISSUE-96: Should the validation results contain stable IDs to indicate the type of violation
- ISSUE-96 Proposals & Votes
ISSUE-78: sh:abstract
PROPOSED: Close ISSUE-78, adding to sh:ShapeClass an optional boolean property sh:abstract.
ISSUE-92: additive repeated properties
PROPOSED: Close ISSUE-92, with no changes at all. The basic combinations in SHACL are non-additive.
- ISSUE-92: Should repeated properties be interpreted as additive or conjunctive?
- ISSUE-92 Proposals & Votes
ISSUE-95: Template Simplifications
PROPOSED: There are two kinds of constraints: built-in and extensions. Extensions are either native or templates.
ISSUE-63: sh:hasShape
PROPOSED: Close ISSUE-63, requiring that engines with full SHACL support must implement a sh:hasShape function (the current specification may have issues with recursion, but these are mentioned in other tickets). Some implementations may use recursive code generation as an optimization.
- ISSUE-63: Nested shapes: sh:hasShape function versus recursive SPARQL code generation
- ISSUE-63 Proposals & Votes
