Disposal of Raised Issues

PROPOSED: Open ISSUE-113, ISSUE-114

• ISSUE-113: Let user interface experts design the connection between SHACL and UI tools
• ISSUE-114: Should SHACL include a grouping mechanism of properties (for UI purposes)

ISSUE-95: Template Simplifications

PROPOSED: There are two kinds of constraints: built-in and extensions. Extensions are either native or templates.

• ISSUE-95: Proposed simplification and clean up of template mechanism
• ISSUE-95 Proposals & Votes

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

ISSUE-97: sh:derivedValues

PROPOSED: Close ISSUE-97, adding sh:derivedValues as proposed

• ISSUE-97: Proposal to define constraints using derived values
• ISSUE-97 Proposals & Votes

ISSUE-112: misuse of RDFS properties

PROPOSED: Close ISSUE-112 replacing the use of rdfs:label and rdfs:comment in property constraints with sh:name and sh:description.

• ISSUE-112: SHACL uses RDFS properties in ways that violate their intended RDFS meaning
• ISSUE-112 Proposals & Votes

ISSUE-87: Turtle file

PROPOSED: Close ISSUE-87 with two files: shacl.ttl and shacl.shacl.ttl as per Arthur Ryman's proposal http://www.w3.org/mid/CAApBiOn9eBvt99Eyu%253DjGUL9FxGHB%252B4r6%253DmPrUrwzCAHjmsQpSA%2540mail.gmail.com

• ISSUE-87: Shall we publish RDF files for the SHACL namespace?
• ISSUE-87 Proposals & Votes
• Turtle file

ISSUE-99: special cases

Discuss ISSUE-99: special treatment of rdfs:Resource and rdf:List in sh:valueClass (and possibly elsewhere)

• ISSUE-99 Proposals & Votes
