RE: [xml-dev] ANN: the first million prime numbers in XML format

Hi Roger,

Interesting thread, with lots of opportunities ;-).  Unfortunately, no luck with the lottery :-<

phew.  *That* was painful.

Why not create a "web service" which calculates the "next" page of prime numbers?
Then, you could use content negotiation to specify the format (xml, json, text, html, other), the language (en, fr, other),
the compression (gzip, other) and if you used a hypermedia format, say "application/vnd.xfront.com.prime-numbers", you could use REST to continue 
retrieving prime numbers forever, if you wanted?

I suggest interactions might look like:

Maybe you should cut down the size of the pages a bit though.  Your thoughts?
