preferred label
No two concepts in the same concept scheme may have the same value for skos:prefLabel in a given language.
The preferred lexical label for a resource, in a given language.
change note
A note about a modification to a concept.
related to
A concept with which there is an associative semantic relationship.
alternative symbolic label
An alternative symbolic label for a resource.
history note
A note about the past state/use/meaning of a concept.
member
A member of a collection.
preferred symbolic label
No two concepts in the same concept scheme may have the same value for skos:prefSymbol.
The preferred symbolic label for a resource.
member list
An RDF list containing the members of an ordered collection.
The following rule applies for this property: [(?c skos:memberList ?l) elementOfList(?e,?l) implies (?c skos:member ?e)]
editorial note
A note for an editor, translator or maintainer of the vocabulary.
example
An example of the use of a concept.
has subject
A concept that is a subject of the resource.
The following rule may be applied for this property: [(?d skos:subject ?x)(?x skos:broader ?y) implies (?d skos:subject ?y)]
identifier
Use or extend this property to indicate any non-URI code that is used to uniquely identify a concept within a conceptual scheme.
This property is now deprecated. Use dc:identifier instead.
hidden label
A lexical label for a resource that should be hidden when generating visual displays of the resource, but should still be accessible to free text search operations.
scope note
A note that helps to clarify the meaning of a concept.
note
A general note, for any purpose.
This property may be used directly, or as a super-property for more specific note types.
This property replaces the two deprecated properties skos:privateNote and skos:publicNote. To describe a note for a particular audience (e.g. 'editor', 'indexer', 'general user') use a note property with a related resource description and the dc:audience property.
has top concept
This property replaces the deprecated skos:TopConcept class.
A top level concept in the concept scheme.
symbolic label
An image that is a symbolic label for the resource.
This property is roughly analagous to rdfs:label, but for labelling resources with images that have retrievable representations, rather than RDF literals.
definition
A statement or formal explanation of the meaning of a concept.
in scheme
A concept may be a member of more than one concept scheme.
A concept scheme in which the concept is included.
alternative label
Acronyms, abbreviations, spelling variants, and irregular plural/singular forms may be included among the alternative labels for a concept. Mis-spelled terms are normally included as hidden labels (see skos:hiddenLabel).
An alternative lexical label for a resource.
has broader
A concept that is more general in meaning.
Broader concepts are typically rendered as parents in a concept hierarchy (tree).
sub-class of
This term has been moved to the 'SKOS Extensions' vocabulary. See http://www.w3.org/2004/02/skos/extensions/
An extension of the 'broader' property to specify the class subsumption (sub-class/super-class) relationship between two concepts. This property is semantically equivalent to the 'rdfs:subClassOf' property.
instance of
An extension of the 'broader' property to specify the instantiation (instance of) relationship between two concepts. This property is semantically equivalent to the 'rdf:type' property.
part of
An extension of the 'broader' property to specify a partitive (part of) relationship between two concepts.
is primary subject of
A resource for which the concept is the primary subject.
is subject of
A resource for which the concept is a subject.
has narrower
A concept that is more specific in meaning.
Narrower concepts are typically rendered as children in a concept hierarchy (tree).
super-class of
This property is the inverse of the 'broaderGeneric' property.
has instance
This property is the inverse of the 'broaderInstantive' property.
has part
This property is the inverse of the 'broaderPartitive' property.
has primary subject
A concept that is the primary subject of the resource.
A resource may have only one primary subject per concept scheme.
This property is the inverse of the 'relatedPartOf' property.
An extension of the 'related' property. Use this property to express a partitive relationship between concepts, where it is desired that such a relationship be treated as associative (i.e. linking separate branches of a hierarchy) and NOT hierarchical.
semantic relation
A concept related by meaning.
This property should not be used directly, but as a super-property for all properties denoting a relationship of meaning between concepts.
subject indicator
A subject indicator for a concept. [The notion of 'subject indicator' is defined here with reference to the latest definition endorsed by the OASIS Published Subjects Technical Committee.]
This property allows subject indicators to be used for concept identification in place of or in addition to directly assigned URIs.
Collection
A meaningful collection of concepts.
Labelled collections can be used with collectable semantic relation properties e.g. skos:narrower, where you would like a set of concepts to be displayed under a 'node label' in the hierarchy.
Concept
An abstract idea or notion; a unit of thought.
Concept Scheme
A concept scheme may be defined to include concepts from different sources.
A set of concepts, optionally including statements about semantic relationships between those concepts.
Thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', and other types of controlled vocabulary are all examples of concept schemes. Concept schemes are also embedded in glossaries and terminologies.
Ordered Collection
An ordered collection of concepts, where both the grouping and the ordering are meaningful.
Ordered collections can be used with collectable semantic relation properties, where you would like a set of concepts to be displayed in a specific order, and optionally under a 'node label'.
public note
A general note intended for public consumption.
This property can be used directly for general notes, or as a super-property for more specific note types where the notes are intended for public consumption.
This property now replaced by skos:note. To describe a note for a particular audience (e.g. 'editor', 'indexer', 'general user') use a note property with a related resource description and the dc:audience property.
Gives labels, comments and definitions in French.
Collectable Property
A property which can be used with a skos:Collection.
The following rule applies for this property: [(?x ?p ?c) (?c skos:member ?y) (?p rdf:type skos:CollectableProperty) implies (?x ?p ?y)]
Gives labels, comments and definitions in German.

SKOS Core Vocabulary 2005-10-14 '2nd W3C Public Working Draft' Edition
Gives labels, comments and definitions in Dutch.
Top Concept
A concept that sits at the top of the concept hierarchy.
This class is now deprecated. To indicate that a concept is a top concept in a scheme, now use the skos:hasTopConcept property.
An RDF vocabulary for describing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, 'folksonomies', other types of controlled vocabulary, and also concept schemes embedded in glossaries and terminologies.

SKOS Core Vocabulary
Gives labels, comments and definitions in Portuguese.
private note
A general note not intended for public consumption.
This property can be used directly for general notes, or as a super-property for more specific note types where the notes are NOT intended for public consumption.
