Optional ReadonlynameHuman-readable name for the property.
Accepts a localised Dictionary or, as a shorthand for the English-only case, a plain
text string, expanded to { en: <value> } on the
resolved property.
Inheritance — cannot be overridden.
Optional ReadonlydescriptionHuman-readable description of the property.
Accepts a localised Dictionary or, as a shorthand for the English-only case, a
Markdown string, expanded to { en: <value> } on the
resolved property.
Inheritance — cannot be overridden.
Optional ReadonlyhiddenExcludes the member from default serialisation.
Inheritance — inherited; conflicting parents without a child override are reported as an error.
Optional ReadonlyforeignMarks the property as owned by the resources in its range.
A foreign property is read-only for the resource declaring it: a retrieval template may ask for it, but a submitted value stating it is rejected, as the link is written by the resources it points at rather than by the one exposing it.
A foreign property is independent from a reverse mapping. A reverse mapping writes an actual inverse
mapping; foreign exposes a read-only view over mappings another property owns and writes nothing on insert.
Inheritance — cannot be overridden.
Optional ReadonlycaptiveMarks the resources in the property range as unable to outlive the resource declaring it.
A captive resource keeps an identity and a lifecycle of its own and may be created, updated and deleted on its own. It stays existentially dependent on the resource declaring the property, though, and is cascade-removed when that resource is deleted.
Captivity is independent from embedding. An embedded resource has no identity or lifecycle of its own (an id
is rejected as a value is validated) and is always managed as part of the resource containing it; a captive
resource has both and may be managed on its own, but does not survive the resource declaring the property.
Inheritance — cannot be overridden.
Optional ReadonlyforwardMaps the property to an absolute IRI for direct mapping.
Accepts an absolute IRI or, as a shorthand, a Namespace resolving the property name against it (for
instance, { forward: schema } on property name yields http://schema.org/name), narrowed on a built
property to the IRI it denotes.
Both forward and reverse mappings write actual property values. This is independent from
foreign, which exposes a read-only view over mappings another property owns.
Inheritance — cannot be overridden.
Optional ReadonlyreverseMaps the property to an absolute IRI for inverse mapping.
Accepts an absolute IRI or, as a shorthand, a Namespace resolving the property name against it (for
instance, { reverse: schema } on property employee yields http://schema.org/employee), narrowed on a built
property to the IRI it denotes.
Both forward and reverse mappings write actual property values. This is independent from
foreign, which exposes a read-only view over mappings another property owns.
Inheritance — cannot be overridden.
Constraints accepted by the member factories.
States how a member is stored, presented and owned, leaving its cardinality to the factory naming it and its bounds to the general-purpose one.
