comment: The subject is an instance of a class.

Concept
type: Class
label: SKOS Concept

is in scheme
definition: Relates a resource (for example a concept) to a concept scheme in which it is included.

preferred label
comment: A resource has no more than one value of skos:prefLabel per language tag, and no more than one value of skos:prefLabel without language tag.
comment: The range of skos:prefLabel is the class of RDF plain literals.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
definition: The preferred lexical label for a resource, in a given language.
sub property of: label

alternative label
comment: The range of skos:altLabel is the class of RDF plain literals.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
definition: An alternative lexical label for a resource.
sub property of: label

has broader
comment: Broader concepts are typically rendered as parents in a concept hierarchy (tree).
definition: Relates a concept to a concept that is more general in meaning.
sub property of: broaderTransitive

has Constraint
comment: A Variable has a Constraint, that confines an Entity involved in the observation.

has ObjectOfInterest
comment: A Variable has an Entity whose Property is observed.

has Property
comment: A Variable has a Property that characterizes an Entity.

Simplified label
comment: For Theia OZCAR information system purpose. This label is used to enhance discoverability on the information system.
