notes on generating the RDF iCalendar schema again

Dan Connolly asked me to work out how to maintain the calendar schema
for the syntactic icalendar to RDF work

http://rdfig.xmlhack.com/2003/02/26/2003-02-26.html#1046281084.080137
http://www.w3.org/2002/12/cal/

The schema is generated from three icalendar files converted to RDF -
see

http://www.w3.org/2002/12/cal/tests/

and
http://www.w3.org/2002/12/cal/Makefile

to see which ones.

The conversion requires CWM and Python 2.2. I got it working on Debian,
although not on Mac Os 10.2 (I sent a bug report
http://lists.w3.org/Archives/Public/www-archive/2003Mar/0012.html).

I don't know much at all about Python, but it worked anyway.

This information is already on the SWAD-Europe calendar wiki:

http://esw.w3.org/t/view/ESW/RdfCalendarSchema

but I'm repeating it here as the machine is currently having some
problems and I need to refer to it.

cheers

Libby
