When exposing a variable in the address space, I thought it would be a good idea want to copy the pattern seen on some OPC UA nodes, so instead of having

Foo (Variable, DataType = X)

I have:

Foo (Variable, DataType = LocalizedText)
Foo.Id (Property, DataType = X)

When I do this, should the BrowseName of Foo.Id be in the OPC UA namespace, or the same namespace as Foo?

If you are defining the property it should be in your namespace.

If you used the standard property “ValueAsText” you would use the UA namespace.

i.e.

Foo (Variable, DataType = X)
Foo.ValueAsText (Variable, DataType = LocalizedText)
