opcua:ObjectType
Mapped https://mapped.com/schema/mapped/1.0/opcua#ObjectType
An OPC UA ObjectType node (OPC 10000-3 §5.5.2), such as FolderType, BaseObjectType, or a companion-spec or vendor type like PumpType. One vertex per ObjectType that an ingested Object names through opcua:hasTypeDefinition, and one per supertype of those, linked with opcua:hasSubtype. Namespace-0 types are included.
Hierarchy
Parent classes: opcua:Node
Subclasses: none, this is a leaf class.

Properties
| Property | Type | Required | Default | Description |
|---|---|---|---|---|
opcua:isAbstract | boolean | The IsAbstract attribute of an opcua:ObjectType, opcua:VariableType or opcua:DataType (OPC 10000-3 §5.5.2, §5.6.5, §5.8.3), written only when true: no node or value is of exactly this type, only of its subtypes. A value whose declared DataType is abstract carries its concrete type in UaTypeId. |
exactType is always opcua:ObjectType.
Inherited properties (18)
| 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 | |||
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. | ||
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:hasSubtype | opcua:DataType, opcua:VariableType, opcua:ObjectType | opcua:isSubtypeOf | 0..* | transitive, canonical A HasSubtype reference (OPC 10000-3 §7.10) from a type to a direct subtype of the same NodeClass: Double to Duration, or BaseAnalogType to AnalogItemType. Only between stored type vertices. |
opcua:isSubtypeOf | opcua:DataType, opcua:VariableType, opcua:ObjectType | opcua:hasSubtype | 0..* | The direct supertype of this type: the inverse of opcua:hasSubtype. OPC UA names it SubtypeOf (OPC 10000-5 §11.10). Following it up to a namespace-0 type says what a vendor type is, such as a MyTempType that subtypes AnalogItemType. |
opcua:isTypeDefinitionOf | opcua:Object | opcua:hasTypeDefinition | 0..* | The Objects or Variables of this type: the inverse of opcua:hasTypeDefinition. OPC UA names it TypeDefinitionOf (OPC 10000-5 §11.12). |
