Hi all,

Unfortunately I wasn’t able to join the call yesterday because I was at a conference. I would have loved to provide some more information or at least share my opinion on the ServerProfileArray and how it is currently treated in the different products we see here. In certification testing we ran into the problem on how the content needs to be set when becoming more strict about the server object. There is already a mantis issue (4344) which asks for clarification of that so you might want to link the new one to: https://apps.opcfoundation.org/mantis/view.php?id=4344
In certification testing we are checking for the content but as long as it is not clearly defined we can only highly recommend to use the unique URIs but can’t fail servers for not using it. Having that said, there are servers out there only using a string like “Methods” or “Methods Server” or “Methods Server Facet”. So having a clarification on the content will be very helpful.

The text “See Part 7 for the definitions of Server Profiles” doesn’t restrict the content to Profiles defined in Part 7 to me. I would rather understand this as one list you can chose from not limiting it to that one list. Anyhow being more precisely is never bad and also will ensure that in the future a client can really interpret the list being provided.
But when already enhancing the wording here I would also suggest to add Facets to the text as well. As they are just a special type of profile but are providing additional feature information they are as important as a full featured profile. But many vendors are not aware of that and think Facets are something different and therefore not listing them.

I’m not as used to writing specs as well as all of you are but maybe something like:
ServerProfileArray lists the URIs of Profiles and Facets that the Server supports. See Part 7 for the definition of Server Profiles and Facets defined by the OPC Foundation specifications. This list should be limited to the Profiles the Server supports in its current configuration which may include Profiles and Facets defined in companion specifications.

Best regards,

Mantis 0004344 covers this issue and also includes the creation of the Errata (1.03.8 and 1.04.8).

Agreed to dup in vF2F.
