Constraints definitions for SKOS and SKOS-XL
Shape file metadata

Implements the following SKOS constraint checks:
- S9 skos:ConceptScheme is disjoint with skos:Concept.
- S13 : skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
- S14 A resource has no more than one value of skos:prefLabel per language tag.
- S27 skos:related is disjoint with the property skos:broaderTransitive.
- S37 skos:Collection is disjoint with each of skos:Concept and skos:ConceptScheme.
- (9.6.4.) SKOS Concepts, Concept Collections and Semantic Relations
- S46 skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch.
- (10.6.2.) Clashes Between Hierarchical (skos:broadMatch skos:narrowMatch) and Associative (skos:relatedMatch, skos:closeMatch, skos:exactMatch) Mappings
- (B.3.4.2). SKOS+XL Labeling Integrity
Some warning and few error constraints are also taken from qSKOS validator [https://github.com/cmader/qSKOS/wiki/Quality-Issues#Labeling_and_Documentation_Issues]
