Summary#

Could the equipment ID go into the “specifier” field of the “describing” message?

Issue text#

The equipment ID is a SEC node property, and it is therefore redundant to put it as the second item of the describe message.

However as the describe/describing message might be extended later, for example to get the description of single modules only, we should specify a fixed word for the second item of the describe message, for example the keyword “ALL” or “All”.

At the meeting in Berlin (2017-05-30) this was discussed, but it was not yet decided the the keyword should be exactly. Until a final decision, SECoP clients should ignore the second item.

Opinions#

We should use key keyword ALL (Markus Zolliker).

Decision#

The decision was taken to use a bare period as placeholder:

describing . {"modules": ...
