<- I'm not 100% clear on what you mean by 'process' here; you hint in the
<- document that RPP can be used for online and offline processes, but also
<- processes such as boiling an agg. An online 'process' could presumably
<- also be called a web service?

Yes indeedy, the main reason I didn't mention this was that I never though
of it ;-)

Is it the intent to be able to describe
<- fully the "API" of the service here?

That's a good way of putting it - but an API usually is defined pretty
completely, I was thinking that an RPP would only require the barest minimum
to allow a single (perhaps set) of process(es) to be carried out, and/or
for discovery of further information/other ways of carrying out the process.

<- I'm a little confused by the reference to the algorithm; surely most of
<- the time one needn't know the algorithm behind a service?

I didn't word this bit very well, I'm pretty much talking of using the
identifier of the algorithm as an identifier for the process (though the URI
might happen to be a URL where e.g. the source code could be found).

<- 8-) Reading the document, I kept coming up with questions and then going
<- back and noticing the answer in the first para of the introduction;
<- there's a lot of info there! It might help to break it up a bit to
<- emphasise each point...

Fair comment - when I get chance, I will.
Meantime I must improve my writing style ;-)

<- There are representations for activities etc from the planning community
<- that might be useful, e.g. http://www.aiai.ed.ac.uk/project/spar/

I've not seen that before - thanks.

<- Could you perhaps add a 'storyboard' example or two of how you envisage
<- RPP being used?

Hmm - I thought about doing this (and maybe I will) but I have doubts about
implying fairly specific applications -  when I tried to describe something
like this in terms of a use case (rather involved : statistical data, a
format convertor, some analysis tools and some XSL stuff), one correspondent
got the impression I was just trying to do data analysis. I've had this idea
on my mind a while, so I fall into the trap of assuming everyone knows what
I'm on about - the wife nods & smiles.

Thanks for your comments,
