Thanks for this Annette,

In my comments below I begin by disagreeing with you but we end up in 
agreement.

Hmm... sorry Annette, I think it's the right place for it.

The purpose of normative information in a best practice document is to 
tell the readers what they ought to be doing, what actions they should 
be taking or not taking.

Well, we could do that but then we're being more prescriptive than we 
need to be and, at the same time, limiting our audience. If we were to 
say something like "you must use DCAT" then we lock out people who 
prefer the alternatives (schema.org, ADMS, CKAN-native and more). The 
more general statement (in BP Provide Metadata) is:

It MUST be possible for data consumers to:
- discover the data;
- understand the nature and structure of the data,
   i.e. what the data describes and how it does it;
- find out the origin of the data and under what terms it may be used.

and then we give more specific advice but it leaves the door open to 
different implementations that achieve the same goal.



  The purpose of a description of an intended outcome is to describe the 
result of taking that action. So we are stuck trying to describe both 
the thing to do and its result in one go.

I don't think so. The result is normative, the how to do it is not.

I agree with that.

  We would also have to rename that piece of the template from "intended 
outcome" to something that makes more sense. If we keep the intended 
outcomes as outcomes, we could choose to put all the normative 
information into the subtitles and beef each of those up into something 
more like a synopsis, which is what they are already approaching.

I wouldn't oppose that.

  I think having only one place where we put the normative text would 
simplify usability of the document.

I am happy with that. In my original suggestion, the Intended outcome 
was the normative statement but the editors added the keywords to the 
subtitle. I'd be happy to follow your suggestion.

Other way round (Share-PSI follows DWBP) but, OK, I take the point.
