Mapped https://mapped.com/schema/mapped/1.0/core#Sensor

A Sensor is an input point that represents the value of a device or instrument designed to detect and measure a variable (ASHRAE Dictionary).

No properties of its own.

exactType is Sensor or the name of one of its subclasses (534 values).

Inherited properties (27)
PropertyTypeRequiredDefaultDescription
bacnet:priority-arraystring
connectedDataSourceIdstringThe id of the origin data source of an entity. This id is already a part of mappingKey but important for faster query.
connectorIdsArray<string>The ids of the connectors associated with the entity.
datatypeObjectYesData type associated with the Point.
dateCreateddateTimeDatetime when it is created.
dateUpdateddateTimeDatetime when it is updated last time.
descriptionstring
enrichmentSourceConnectorIdstringThe id of the source connector with which the vertex, whether it's a property bag or a derived entity, is associated.
idstringYesA globally unique ID in Mapped services.
isFusionDerivedbooleanfalseIf 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.
isVirtualbooleanfalseIf this is true, the corresponding entity is virtual, meaning it doesn't exist in the real world but fabricated in the Mapped's system.
mappingKeystringThe origin of the entity. More detailed definition is available at here.
maxLimitdouble
minLimitdouble
namestring
organizationIdstringYesThe id of the organization that owns the entity.
readOnlyboolean
seeAlsostring
stageNumberintegerThe 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
stateTextsArray<string>An array holding textual representation of numeric values in state-related Points such as alarms, statuses, etc.
stepdoubleData type associated with a specific Point.
systemTypeArray<Object>A system type of the system the entity is associated.
typeArray<Object>YesThe entity's types or classes. The types are determined within the class hierarchy. This is an stringified alias for rdf:type.
unitObjectA unit string (for now) associated with the point
unusedbooleanfalseIf 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.
valueMapMap<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.
valueTypestringData type associated with a specific Point.

Relationships​

No relationships of its own.

Inherited relationships (17)
RelationshipTargetsInverseCardinalityNotes
contributesPropertyMetahasPropertyContributedFrom0..*transitive, canonical
Mapped's internal relationship indicating that a vertex is contributing a property/value to another vertex.
hasDerivationPointisDerivedFrom0..*transitive, canonical
The points whose values were computed from this point's values.
hasExtendedPropertyExtendedProperty0..*transitive, canonical
The entity's customer-defined extended properties, one node per key-value pair.

Links an entity to an external reference object (e.g., a BACnet object) that describes its origin or counterpart in an external system.
hasGeneratedArtifactOpenUSD_LayerisGeneratedFrom0..*The layers generated from this source.
hasHeartbeatHeartbeatisHeartbeatOf0..1transitive, 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.
hasIdentityIdentity0..*transitive, canonical
hasPrimBindingOpenUSD_Prim_BindingisPrimBindingOf0..*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.
hasPropertyBagPropertyBag0..*transitive, canonical
hasPropertyContributedFromPoint, Postal_Address_Identity, Name_Identity, PropertyBagcontributesProperty0..*Mapped's internal relationship indicating that a vertex has a contributing property/value from another vertex.
isBilledToAccounthasBill0..1The bills in this entity is billed to an account.
isConstraintTargetSpatial_ConstraintconstrainsAgainst0..*The constraints evaluated against this representation or entity.
isDerivedFromPointhasDerivation0..*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.
