Implementing localized browse names|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

I have created a node and set the DisplayName to a LocalizedText with the Key property as a string that I am able to translate. I am trying to find a way that when a client browses this node, the display name will be returned to them in the clients preferred locale.

Here’s what I tried:

• Overriding CreateResourceManager on my subclass of StandardServer, then returning a subclass of ResourceManager that overrides the Translate methods, and then performing the translation and returning a new LocalizedText object in the preferred locale.

  Result:
  This seems to work when emitting events, but does not work for node browsing.

• Setting the OnReadDisplayName field of the node I have created, then use the ISystemContext.UserIdentity to find the preferred locale, and setting the LocalizedText reference to a new object with the preferred locale.

  Result:
  This seems to work when reading attributes of a node, but also does not work for node browsing.

I have dived into the codebase and looked at things like CustomNodeManager2.Browse, CustomNodeManager2.GetReferenceDescription, but I am really struggling to find a way to inject the localized text into the response.

The only chance I have seen would be to replace BinaryEncoder with a specialized BinaryEncoder that when WriteLocalizedText is called, it translates the text before writing to the output stream. This looks like quite a difficult task and it’s possible I will find some other blockers while doing it that prevents this working too (e.g. it is not immediately clear how I would determine what the preferred locale is at this point in the code).

Before I try to tackle this task, I hoped somebody would be able to provide some guidance or give me some insight:

1. Is providing localized display names for browsed nodes a sensible idea? Or is the intention that display names on the browse nodes would always be in a single locale?
2. Is there an easier way to achieve this?

Any help at all would be appreciated, thank you.
