Properties

Property	Type	Required	Default	Description
`bacnet:priority-array`	`string`
`datatype`	`Object`	Yes		Data type associated with the Point.
`isFusionDerived`	`boolean`		`false`	If `true`, the values of this point are produced by fusing several underlying sources rather than by a single direct measurement. This describes how the value was derived, not whether the point or its device is physical: a vendor inertial navigation unit or a vendor location engine is a real device whose output is fusion-derived, so this is independent of `isVirtual`. A consumer must not treat a fusion-derived value as evidence independent of the sources it was fused from.
`maxLimit`	`double`
`minLimit`	`double`
`readOnly`	`boolean`
`stageNumber`	`integer`			The discrete stage number that identifies which operational stage a command or status point represents in multi-stage equipment. Stage numbers typically start at 1 for the first stage and increment sequentially for additional stages
`stateTexts`	`Array<string>`			An array holding textual representation of numeric values in state-related Points such as alarms, statuses, etc.
`step`	`double`			Data type associated with a specific Point.
`unit`	`Object`			A unit string (for now) associated with the point
`unused`	`boolean`		`false`	If it true, the point is unused but a placeholder in the controller. Such points are exposed by the data source but not actively defined or used.
`valueMap`	`Map<integer, string>`			A map holding textual representation of numeric values in state-related Points such as alarms, statuses, etc. Keys are the raw values in integer and the values are the interpretation of the raw values. E.g., 0: ON, 2: OFF, etc.
`valueType`	`string`			Data type associated with a specific Point.

exactType is Point or the name of one of its subclasses (1554 values).

Inherited properties (14)

Property	Type	Required	Default	Description
`connectedDataSourceId`	`string`			The id of the origin data source of an entity. This id is already a part of `mappingKey` but important for faster query.
`connectorIds`	`Array<string>`			The ids of the connectors associated with the entity.
`dateCreated`	`dateTime`			Datetime when it is created.
`dateUpdated`	`dateTime`			Datetime when it is updated last time.
`description`	`string`
`enrichmentSourceConnectorId`	`string`			The id of the source connector with which the vertex, whether it's a property bag or a derived entity, is associated.
`id`	`string`	Yes		A globally unique ID in Mapped services.
`isVirtual`	`boolean`		`false`	If this is `true`, the corresponding entity is virtual, meaning it doesn't exist in the real world but fabricated in the Mapped's system.
`mappingKey`	`string`			The origin of the entity. More detailed definition is available at here.
`name`	`string`
`organizationId`	`string`	Yes		The id of the organization that owns the entity.
`seeAlso`	`string`
`systemType`	`Array<Object>`			A system type of the system the entity is associated.
`type`	`Array<Object>`	Yes		The entity's types or classes. The types are determined within the class hierarchy. This is an stringified alias for `rdf:type`.

Relationships

Relationship	Targets	Inverse	Cardinality	Notes
`hasDerivation`	Point	`isDerivedFrom`	0..*	transitive, canonical The points whose values were computed from this point's values.
`hasExternalReference`	bacnet:BinaryInputObject, bacnet:AnalogValueObject, bacnet:AnalogOutputObject, bacnet:BinaryOutputObject, bacnet:MultistateOutputObject, opcua:Variable, bacnet:MultistateValueObject, bacnet:MultistateInputObject, bacnet:AnalogInputObject, bacnet:BinaryValueObject		0..*	transitive, canonical Links an entity to an external reference object (e.g., a BACnet object) that describes its origin or counterpart in an external system.
`hasHeartbeat`	Heartbeat	`isHeartbeatOf`	0..1	transitive, canonical A point that represents the heartbeat of the data source such as a device or a connector which is the source of the corresponding Point.
`hasPropertyContributedFrom`	Point, Postal_Address_Identity, Name_Identity, PropertyBag	`contributesProperty`	0..*	Mapped's internal relationship indicating that a vertex has a contributing property/value from another vertex.
`isBilledTo`	Account	`hasBill`	0..1	The bills in this entity is billed to an account.
`isDerivedFrom`	Point	`hasDerivation`	0..*	The points whose values this point's values were computed from, such as the source sensors whose observations a fused point fuses. This describes value lineage: it says which inputs produced this point's values, not how they were combined. Distinguished from `contributesProperty`, which is property-bag lineage for a single named property value, and from reification, which creates an entity from another entity's identifier rather than from its values. A consumer must not treat this point as evidence independent of the points it is derived from.
`isHostedBy`	Thing	`hosts`	0..*
`isPartOf`	Collection	`hasPart`	0..*
`isPointOf`	Thing, Place, Collection	`hasPoint`	0..*

Relationship	Targets	Inverse	Cardinality	Notes
`contributesProperty`	`Meta`	`hasPropertyContributedFrom`	0..*	transitive, canonical Mapped's internal relationship indicating that a vertex is contributing a property/value to another vertex.
`hasExtendedProperty`	ExtendedProperty		0..*	transitive, canonical The entity's customer-defined extended properties, one node per key-value pair.
`hasGeneratedArtifact`	OpenUSD_Layer	`isGeneratedFrom`	0..*	The layers generated from this source.
`hasIdentity`	Identity		0..*	transitive, canonical
`hasPrimBinding`	OpenUSD_Prim_Binding	`isPrimBindingOf`	0..*	transitive, canonical Attaches a prim address. Used directly on an entity for pure addressing that carries no physical claim, and on a Representation or level-of-detail heuristic to realise it in USD.
`hasPropertyBag`	PropertyBag		0..*	transitive, canonical
`isConstraintTarget`	Spatial_Constraint	`constrainsAgainst`	0..*	The constraints evaluated against this representation or entity.
`isSubjectOfConstraint`	Spatial_Constraint	`constrainsSubject`	0..*	The constraints this entity is the subject of.
