type: Entity
definition: [Wikipedia] Lanthanum is a chemical element with the symbol La and atomic number 57. It is a soft, ductile, silvery-white metal that tarnishes slowly when exposed to air. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype. Lanthanum is traditionally counted among the rare earth elements. The usual oxidation state is +3. Lanthanum has no biological role in humans but is essential to some bacteria. It is not particularly toxic to humans but does show some antimicrobial activity.

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

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.
