Status: stable
broader: Natural superficial deposit
definition: Silt [Unlithified Deposits Coding Scheme] - A type of natural superficial deposit. The Unlithified Deposits Coding Scheme was developed as a way of coding unlithified deposits (also commonly referred to as superficial deposits, unconsolidated deposits, or engineering soils) that is consistent with civil engineering industry usage (BS5930).

Rock Classification Scheme - single rock types sub-scheme
Status: stable
definition: Subscheme of Rock Classification Scheme that classifies single rock types in a class-sub class hierarchy. Volumes 1 to 4 of published reports.

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.

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.

Silt [UDCS]
Status: stable
definition: Silt [Unlithified Deposits Coding Scheme] - A type of natural superficial deposit. The Unlithified Deposits Coding Scheme was developed as a way of coding unlithified deposits (also commonly referred to as superficial deposits, unconsolidated deposits, or engineering soils) that is consistent with civil engineering industry usage (BS5930).

The BGS Rock Classification Scheme
Status: stable
definition: The BGS Rock Classification Scheme classifies all types of earth material or other substance that may be recorded in a geological log or section. This is a combined scheme that consists of all concepts from the 3 sub-schemes. The 3 sub-schemes cover different sets of terms (single rocks, composite rocks, dummy rocks) and have different semantics of hierarchical relationship

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.
