Inherited properties (27)

Property	Type	Required	Default	Description
bacnet:priority-array	string
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.
datatype	Object	Yes		Data type associated with the Point.
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.
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.
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.
maxLimit	double
minLimit	double
name	string
organizationId	string	Yes		The id of the organization that owns the entity.
readOnly	boolean
seeAlso	string
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.
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.
unit	Enum<string> 97 values BBL_UK_PET-PER-DAY, BBL_UK_PET-PER-HR, BBL_UK_PET-PER-MIN, BBL_UK_PET-PER-SEC, BBL_US-PER-DAY, BBL_US-PER-MIN, BBL_US_PET-PER-HR, BBL_US_PET-PER-SEC, BU_UK-PER-DAY, BU_UK-PER-HR, BU_UK-PER-MIN, BU_UK-PER-SEC, BU_US_DRY-PER-DAY, BU_US_DRY-PER-HR, BU_US_DRY-PER-MIN, BU_US_DRY-PER-SEC, CentiM3-PER-DAY, CentiM3-PER-HR, CentiM3-PER-MIN, CentiM3-PER-SEC, DeciM3-PER-DAY, DeciM3-PER-HR, DeciM3-PER-MIN, DeciM3-PER-SEC, FT3-PER-DAY, FT3-PER-HR, FT3-PER-MIN, FT3-PER-SEC, GAL_UK-PER-DAY, GAL_UK-PER-HR, GAL_UK-PER-MIN, GAL_UK-PER-SEC, GAL_US-PER-DAY, GAL_US-PER-HR, GAL_US-PER-MIN, GAL_US-PER-SEC, GI_UK-PER-DAY, GI_UK-PER-HR, GI_UK-PER-MIN, GI_UK-PER-SEC, GI_US-PER-DAY, GI_US-PER-HR, GI_US-PER-MIN, GI_US-PER-SEC, IN3-PER-HR, IN3-PER-MIN, IN3-PER-SEC, KiloL-PER-HR, L-PER-DAY, L-PER-HR, L-PER-MIN, L-PER-SEC, M3-PER-DAY, M3-PER-HR, M3-PER-MIN, M3-PER-SEC, M3-PER-YR, MilliL-PER-DAY, MilliL-PER-HR, MilliL-PER-MIN, MilliL-PER-SEC, OZ_VOL_UK-PER-DAY, OZ_VOL_UK-PER-HR, OZ_VOL_UK-PER-MIN, OZ_VOL_UK-PER-SEC, OZ_VOL_US-PER-DAY, OZ_VOL_US-PER-HR, OZ_VOL_US-PER-MIN, OZ_VOL_US-PER-SEC, PINT_UK-PER-DAY, PINT_UK-PER-HR, PINT_UK-PER-MIN, PINT_UK-PER-SEC, PINT_US-PER-DAY, PINT_US-PER-HR, PINT_US-PER-MIN, PINT_US-PER-SEC, PK_UK-PER-DAY, PK_UK-PER-HR, PK_UK-PER-MIN, PK_UK-PER-SEC, PK_US_DRY-PER-DAY, PK_US_DRY-PER-HR, PK_US_DRY-PER-MIN, PK_US_DRY-PER-SEC, QT_UK-PER-DAY, QT_UK-PER-HR, QT_UK-PER-MIN, QT_UK-PER-SEC, QT_US-PER-DAY, QT_US-PER-HR, QT_US-PER-MIN, QT_US-PER-SEC, YD3-PER-DAY, YD3-PER-HR, YD3-PER-MIN, YD3-PER-SEC			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.

Relationships

No relationships of its own.

Inherited relationships (17)

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.
hasDerivation	Point	isDerivedFrom	0..*	transitive, canonical The points whose values were computed from this point's values.
hasExtendedProperty	ExtendedProperty		0..*	transitive, canonical The entity's customer-defined extended properties, one node per key-value pair.
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.
hasGeneratedArtifact	OpenUSD_Layer	isGeneratedFrom	0..*	The layers generated from this source.
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.
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
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.
isConstraintTarget	Spatial_Constraint	constrainsAgainst	0..*	The constraints evaluated against this representation or entity.
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..*
isSubjectOfConstraint	Spatial_Constraint	constrainsSubject	0..*	The constraints this entity is the subject of.
