Summary0005759: Feature Request: Information on Deprecated parts of the Information Model
Description

The information model is the interface to an OPC UA server.
New versions of a server might support new information models (e.g. standardized information models) providing the same information in a standardized way.

In order to support old clients, the new server version might still support the old information model in the new version in order not to break connections to the old client.

It would be desirable to mark parts of the information model as Deprecated, so new developed applications connecting to the server would only use the new information model parts.

Potential solution:

  • Attribute as flag on each node indicating if node is deprecated.
  • As addition define standardized view only showing the none-deprecated nodes, so clients can easily build up a view of the server only showing the none-deprecated nodes.

Remarks:

  • Attribute allows Properties to become Deprecated.
  • Many servers today do not use specific TypeDefinitions, therefore it is required to define Deprecated also on instances, not only on types.
TagsNo tags attached.

During June Quarterly WG meeting we agreed to define a 'isDeprecated' reference type.
The SourceNode is the deprecated Node and can be of any Node Class. The TargetNode is a Version Object.
The Version Object would include what version of the spec that it was first deprecated. We will not define anything more than a subtype of BaseObjectType.
