Particle Aspect Ratio

"This file contains the CGI Particle Aspect Ratio vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. AspectRatio describes the geometry of particles based on the ratios of lengths of long, intermediate and short axes of grains. Equates to sphericity in sedimentary rocks (ie: the degree to which the shape of a particle approximates a sphere). A quantitative specification is based on the ratio of lengths of long, intermediate and short axes of grain shape (Sneed and Folk, 1958; Zingg, 1935).

Particle Shape

"This file contains the CGI Particle Shape vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The Shape attribute describes, a) the development of crystal faces bounding particles in crystalline compond materials, and b) surface rounding of grains in sedimentary rocks. Roundness is a measure of the sharpness of the edges between surfaces bounding a particle (see Jackson, 1997; Wadell, 1932) and is an indication of the degree of abrasion of a clastic particle.

Particle Type

"This file contains the CGI Particle type vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. Used to specify particleType in particleTypeDescription associated with a compoundMaterial. Terms to specify the nature of individual particles of each constituent in an aggregation, based mostly on their genesis. Because the constituents are identifiable parts, the part units must have some definition. Examples include clasts, crystals, pore space, material fossil.

Processing Activity

"This file contains the CGI Processing Activity vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts to categorize processing activities associated with a mining activity. A miningActivity and subsequent processingActivity provide the linkage between a minedMaterial and a mine Product. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."

Proportion Term

"This file contains the CGI Proportion Term vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. This vocabulary provides terms that may be used to qualitatively express abundance of composition parts in a geologic unit or earth material description. Quantity that specifies the fraction of the geologic unit composed of the compound material. This vocabulary is used for GeologicUnit.GeologicUnitPart.proportion, GeologicUnit.compositionPart.proportion, and for compoundMaterial.ConsituentPart.proportion.

Raw Material Role

"This file contains the CGI Raw Material Role vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts for categorizing raw material relationships with Earth Resource occurrences. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."

Reserve Assessment Category

"This file contains the CGI Reserve Assessment Category vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts for classifying reserve types associated with Earth resource occurrences. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."

NPG Severity Levels Ontology

"The SeverityLevels Ontology is a modelling of the syslog message severity values from RFC 5424. (...) This is used in conjunction with the SPIN vocabulary to label exceptions that we may create in our build process. This process makes extensive use of SPIN rules. Validation tests are applied to a given data model via a SPARQL construct query and any exceptions raised are added to the :Graph object associated to a class. This :Graph object is used to add RDF annotations about the class instance named graph."

NPG Publish States Ontology

"The PublishStates Ontology is a categorization of the various states that mark the publishing status of a publication. In particular, these indicate stages in the publishing workflow. For example, a siginificant state change for an online article publication occurs when it is bound to an issue publication, whereby it transitions from an earlier 'Advance online publication' state to an 'Issue publication' state. These state changes are managed by publish-event objects which capture both the publish-state and the date (or datetime) at which this event occurs."
