Nitrogen dioxide
type: Concept
type: Entity
definition: [Wikipedia] Nitrogen dioxide is a chemical compound with the formula NO2. It is one of several nitrogen oxides. NO2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas. It can be fatal if inhaled in large quantity.

definition
definition: A statement or formal explanation of the meaning of a concept.
sub property of: note

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

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 broader match
definition: skos:broadMatch is used to state a hierarchical mapping link between two conceptual resources in different concept schemes.
sub property of: has broader
sub property of: mappingRelation

has related match
definition: skos:relatedMatch is used to state an associative mapping link between two conceptual resources in different concept schemes.
sub property of: related
sub property of: mappingRelation

has exact match
comment: skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch.
definition: skos:exactMatch is used to link two concepts, indicating a high degree of confidence that the concepts can be used interchangeably across a wide range of information retrieval applications. skos:exactMatch is a transitive property, and is a sub-property of skos:closeMatch.
sub property of: has close match

has close match
definition: skos:closeMatch is used to link two concepts that are sufficiently similar that they can be used interchangeably in some information retrieval applications. In order to avoid the possibility of "compound errors" when combining mappings across more than two concept schemes, skos:closeMatch is not declared to be a transitive property.
