Re: Recipe for Shops: Showing up in Yahoo and in the Web of Data in One Turn

Interesting. I guess this is another argument/example pro Hugh 
Glaser's idea of simply conflating resource IDs for the sake of
"deployability". The example types <#business> as Vcard, Business
and also as BusinessEntity which would usually be considered wrong
RDF, but, as argued before, is more intuitive for HTML authors, 
especially if they found their way to the SemWeb through pragmatic
solutions like microformats. We should really give this contextual
semantics idea another thought.

(I fear you'll lose a significant chunk of the possible audience at 
"change your DTD" and "add ... to the head tag", these sort of tweaks
are not necessarily easy to do in CMS-based or commercial publishing 
tools unless there is a dedicated plugin that is not erased with the 
next site upgrade. For root/head-level changes, the content *authors*
have to coordinate their tasks with the tech/site *admins*, which 
leads to non-trivial friction loss and hence lowers the deployment 
probability.)

A general suggestion would be to keep the added markup at a minimum,
until GR is more deployed and people start asking for more on their
own. Remove as many non-mandatory descriptions as possible, at least
if the recipes are targeted at newcomers. Stuff like
"ProductOrServicesSomeInstancesPlaceholder" or
"LocationOfSalesOrServiceProvisioning" is probably not very 
attractive to web dev people who are only just getting acquainted 
with structured markup and want to check out if/how it works.

I *personally* think that RDF-in-HTML snippets are most convincing 
when the amount of additional RDF markup does not outweigh the 
human-oriented content. Otherwise it becomes hard to track the 
initial meaning of the page and examples become less illustrative.
Maybe drop some of the @typeofs which repeat the @rel values (e.g. 
as in
   <div rel="gr:hasOpeningHoursSpecification">
      <div typeof="gr:OpeningHoursSpecification">
), or cheat visually by picking some shorter, less Cyc/AI-like 
predicate names, perhaps? 

Just some thoughts,
Benji
