Description
A Device performing a specific Function may generate results. These results are typically consumed by one or more applications which may not run on the Device itself.
The generating Device exposes the results such that they can be retrieved by the application via OPC UA. The results data include the results themselves, but also metadata such as results templates, user information, timestamps, action identifiers, and sample Ids.
A Device can also provide the capability to observe intermediate/partial results, such that an application can monitor the execution of a Function on the Device.
There may be specific cases in which a consuming application may need to retrieve the results via an alternative interface. In these cases, the Device exposes the URI where the results reside and can be accessed via authenticated access. The possibility to retrieve intermediate/partial results via an alternative interface is outside the scope of this specification.
