A constraint on some property e.g. wavelength = 200 nm.
Attribute | Definition | Type | Voidability |
---|---|---|---|
constrainedProperty | The property being constrained. e.g. ‘ colour ’ if the constraint is ‘ colour = blue ’ . | PhenomenonTypeValue | |
label | A human readable title for the constraint as a whole. | CharacterString |
A constraint based on some qualifying category. e.g. colour = ‘ red ’ .
This type is a sub-type of Constraint.
Attribute | Definition | Type | Voidability |
---|---|---|---|
comparison | A comparison operator. In the case of a category constraint it should be ‘ equalTo ’ or ‘ notEqualTo ’ . | ComparisonOperatorValue | |
value | The value of the property that is constrained e.g. ‘ blue ’ (if the constrained property is colour). | CharacterString |
A numerical range constraint on some property e.g. wavelength ≥ 300 nm and wavelength ≤ 600 nm.
This type is a sub-type of Constraint.
Attribute | Definition | Type | Voidability |
---|---|---|---|
value | The numerical value range of the property that is constrained. | RangeBounds | |
uom | Units of measure used in the constraint. | UnitOfMeasure |
The start and end bounding values of a numerical range (e.g. start ≥ 50, end ≤ 99).
Attribute | Definition | Type | Voidability |
---|---|---|---|
startComparison | The comparator used for the lower range limit (e.g. greaterThanOrEqualTo). | ComparisonOperatorValue | |
rangeStart | The lower limit of the range. | Real | |
endComparison | The comparator used for the upper range limit (e.g. lessThan). | ComparisonOperatorValue | |
rangeEnd | The upper limit of the range. | Real |
A numerical scalar constraint on some property e.g. length ≥ 1 m.
This type is a sub-type of Constraint.
Attribute | Definition | Type | Voidability |
---|---|---|---|
value | The numerical value of the property that is constrained. | Real | |
comparison | The comparator to be used in the constraint e.g. greaterThan. | ComparisonOperatorValue | |
uom | Units of measure used in the constraint. | UnitOfMeasure |
A constraint which is not modelled in a structured way but may be described using the freetext ‘ description ’ attribute.
This type is a sub-type of Constraint.
Attribute | Definition | Type | Voidability |
---|---|---|---|
description | A description of the constraint. | CharacterString |
A description of some statistical measure e.g. ‘ daily maximum ’ .
Attribute | Definition | Type | Voidability |
---|---|---|---|
label | A human readable title for the statistical measure. | CharacterString | |
statisticalFunction | A statistical function e.g. mean. | StatisticalFunctionTypeValue | |
aggregationTimePeriod | A temporal range over which a statistic is calculated. e.g. a day, an hour. | TM_Duration | |
aggregationLength | A one dimensional spatial range over which a statistic is calculated, for example 1 metre. | Length | |
aggregationArea | A two dimensional spatial range over which a statistic is calculated, for example 1 square metre. | Area | |
aggregationVolume | A three dimensional spatial range over which a statistic is calculated, for example 1 cubic metre. | Volume | |
otherAggregation | Any other type of aggregation. | Any |
Association role | Definition | Type | Voidability |
