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. Objects, Variables and Properties are ingested, with the types they use and those types' supertypes; Method, View and ReferenceType nodes are not. A node's OPC UA Properties are attached with opcua:hasProperty as opcua:Property vertices, except the standard Data Access ones, which become part of their opcua:Variable.

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 opcua:browseNameNamespaceUri. The DisplayName and Description attributes are stored as mapped:name and mapped:description. | ||
opcua:browseNameNamespaceUri | string | The namespace of the node's BrowseName (OPC 10000-3 §8.3) as a URI: its NamespaceIndex resolved through the server's NamespaceArray, http://opcfoundation.org/UA/ for namespace 0. Not the NodeId's namespace: a child that a type declares has its type's namespace. It tells a companion-spec name, such as the DI SerialNumber, from a vendor's. | ||
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:statusCode | string | The OPC UA StatusCode (OPC 10000-4 §7.38), as its symbolic name such as BadNotReadable, of the connector's read of this node's data, written only when it isn't Good. On an opcua:Property it explains the value: a failed read leaves opcua:value out, and a value that can't be decoded is kept undecoded. On a type vertex it says why the type couldn't be read, leaving a placeholder with only opcua:nodeId. |
exactType is opcua:Node or the name of one of its subclasses (7 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. |

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. |
