Vocabularies

The code lists that ODS fields take their values from: units, quantities, types and classes, by module. A field that names a vocabulary takes only its codes. Each module has one quantities vocabulary: the codes for what an amount describes, with the unit and the valid range of each.

Core

core/activity_types (7)
What sort of work an Activity is.
core/bin_sets (2)
Standard sets of bins that an axis's `bins.set` can name.
core/data_tiers (7)
How strong a source of data is, for an Origin's `tier`, strongest first.
core/feature_types (8)
What sort of feature a Feature is.
core/geographic_identifier_types (6)
What sort of geographic identifier a GeographicIdentifier is.
core/geometry_changes (12)
What a conversion to GeoJSON changed in a shape, for a change of an Original.
core/instrument_types (8)
What sort of instrument an Instrument is.
core/operating_state_types (8)
What sort of state an OperatingState is.
core/permit_types (4)
What sort of permit a Permit is.
core/positioning_methods (14)
How a position was obtained, for a Positioning's `method`.
core/quantities (57)
What an amount describes: the codes for a Property's `type`, an Axis's `quantity`, an Emission's `type`, an Evidence's `observed` and a Criterion's `metric`. Each term states its unit and valid range.
core/receptor_classes (9)
Classes of receptors, for a Feature's `receptorClass`. A framework's criteria apply by class.
core/roles (10)
The part a Link's target plays for the record that holds the link, for a Link's `role`.
core/source_types (16)
What sort of source a Source is. The equipment terms follow the equipment classes of ISO 14224:2016.
core/structure_types (7)
What sort of structure a Structure is.
core/units (47)
Units that a Value's `unit` can name. Codes follow the unit symbols, with `.` for a product and `/` for a quotient.
