Disposal of Raised Issues


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-97: sh:derivedValues

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

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-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-99: special cases

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