opcua:Node
Mapped https://mapped.com/schema/mapped/1.0/opcua#Node
Abstract. A node in an OPC UA server's address space (OPC 10000-3 §5.2, Base NodeClass), carrying the attributes every node shares. Only Object and Variable nodes are ingested; Method, View and type nodes are not.

Properties
| Property | Type | Required | Default | Description |
|---|---|---|---|---|
opcua:browseName | string | The name part of the node's BrowseName (OPC 10000-3 §5.2.4), a QualifiedName; the namespace part is dropped. The DisplayName and Description attributes are stored as mapped:name and mapped:description. | ||
opcua:nodeId | string | Yes | The node's NodeId (OPC 10000-3 §5.2.2) in the string form of OPC 10000-6 §5.1.12: nsu=<namespace URI>;<identifier> for every namespace except 0, and the bare <identifier> (such as i=58) for namespace 0. GUID identifiers are uppercase. It is the deduplication key for OPC UA nodes, so a node must always produce the same string. | |
opcua:typeDefinition | string | BrowseName of the node's HasTypeDefinition target (OPC 10000-3 §7.13), such as AnalogItemType or FolderType. The type is referenced by name rather than stored as a vertex. | ||
opcua:typeDefinitionId | string | NodeId of the node's HasTypeDefinition target, in the opcua:nodeId string form. A namespace-0 type is a bare i=…; for any other type, the nsu= identifies the companion specification or vendor that defines it. |
exactType is opcua:Node or the name of one of its subclasses (3 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 |
|---|---|---|---|---|
opcua:organizedBy | opcua:Object, opcua:Server | opcua:organizes | 0..* | The Object or server that groups this node: the inverse of opcua:organizes, OPC UA's OrganizedBy (OPC 10000-5 §11.6). |
Inherited relationships (8)
| 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. |
