definition: Neoproterozoic Era is a division of Precambrian geological time. It is the last of the three eras of the Proterozoic Eon. It is preceded by the Mesoproterozoic Era and succeeded by the Paleozoic Era (Phanerozoic Eon) (Geologic Time Scale 2020, fig. 2.1; https://timescalefoundation.org/).

Description
description: Description may include but is not limited to: an abstract, a table of contents, a graphical representation, or a free-text account of the resource.

Identifier
description: Recommended practice is to identify the resource by means of a string conforming to an identification system. Examples include International Standard Book Number (ISBN), Digital Object Identifier (DOI), and Uniform Resource Name (URN). Persistent identifiers should be provided as HTTP URIs.

Source
description: This property is intended to be used with non-literal values. The described resource may be derived from the related resource in whole or in part. Best practice is to identify the related resource by means of a URI or a string conforming to a formal identification system.

has broader
definition: Relates a concept to a concept that is more general in meaning.

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

has exact match
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.

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

has narrower
definition: Relates a concept to a concept that is more specific in meaning.

notation
definition: A notation, also known as classification code, is a string of characters such as "T58.5" or "303.4833" used to uniquely identify a concept within the scope of a given concept scheme.

preferred label
definition: The preferred lexical label for a resource, in a given language.

Registry Status Vocabulary
definition: This vocabulary is a re-published and only marginally changed version of the Registry Ontology's (http://epimorphics.com/public/vocabulary/Registry.html) *Status* vocabulary (online in RDF: http://purl.org/linked-data/registry). The only real change to content has been the addition of the term `unstable`. This re-publication has been performed to allow the IRIs of each vocab term (skos:Concept) to resolve to both human-readable and machine-readable forms of content (HTML and RDF), using HTTP content negotiation. Note that just like the original form of this vocabulary, while it is a SKOS vocabulary implemented as a single skos:ConceptScheme, it is also an OWL Ontology and that each *Status* is both a skos:Concept and a reg:Status individual.

Cryogenian Period
Status: stable
definition: Cryogenian Period is a division of Precambrian geological time. It is the second of the three periods of the Neoproterozoic Era. It is preceded by the Tonian Period and succeeded by the Ediacaran Period (Geologic Time Scale 2020, fig. 2.1; https://timescalefoundation.org/).

definition: Ediacaran Period is a division of Precambrian geological time. It is the last of the three periods of the Neoproterozoic Era. It is preceded by the Cryogenian Period and succeeded by the Cambrian Period (Paleozoic Era) (Geologic Time Scale 2020, fig. 2.1; https://timescalefoundation.org/).

Geochronology Division
Status: stable
definition: Divisions of geological time from source table DIC_GEOCHRON. The BGS Geochronology Dataset is based on The Geologic Time Scale 2012 by F M Gradstein, J G Ogg, M Schmitz and G Ogg (2012), with additions. The result is a composite geological time scale that will be updated as improved timescales become available.

Concept
definition: An idea or notion; a unit of thought.

stable
definition: An entry that is seen as having a reasonable measure of stability, may be used to mark the full adoption of a previously 'experimental' entry.
