Now that the f2f2 minutes have been published I can see that this [1] is 
supposed to be a replacement for the vanished use case on Publication.

On the one hand this does seem to be a perfectly good use case and I'd be 
happy to see some improved [*] version of it in the second UCR draft.

On the other hand I don't think it is a complete replacement. The essence 
of the original publication use case [2] was the additional requirement for 
a human legible syntax that could be used to enable publication of rules 
for human developers. That was put up as a strawman to encourage us to 
explicitly consider whether a legible syntax (alongside the main XML or RDF 
syntax) should be within scope. Axel's new use case has no such 
requirement. The alleged requirement for human legibility is not quite the 
same as the human orientedness called for in UC 2.5.


[*] Some comments towards such a tidy up:
- if those data examples are to be included they should be RDF
- the movie/sciFiMovie rule would be better expressed using rdfs:subClassOf
- either delete or rephrase the value-judgement-full statement:
Recursive dependencies among the interlinked rulesets greatly extend and 
generalize the simple one-way RDF data access via SPARQL.
Sparql can explicitly query multiple datasets and can implement the 
alternativeimdb examples.
