summary of IRC RDF calendar meeting Wednesday March 12th 2003,17:00 UTC

From: Libby Miller <Libby.Miller@bristol.ac.uk>
Date: Mon, 17 Mar 2003 14:41:21 +0000 (GMT)

Thanks to everyone who came along.
I think the main item of interest was a last minute addition (5) below -
a motivating example from Dan Brickley which resulted in icalendar and
RDF versions that can be used as a testcase. This is a very intersting
way of getting testcases, and I'd encourage people to send more to this

Summary of agenda items
(Agenda - see

1: GPL'ed code under http://www.w3.org/2002/12/cal/

RESOLVED: "For now, do not check in GPL code. Establishing a
GPL-friendly repository or part of one remains on the agenda"

This was because we didn't want people to get confused about the license
of any tests.

 17:55:18   <libby>very important that they don;t get confused and think
the tests are gpled...

also: the code we were refering to is at a stable url
(http://www.ilrt.bris.ac.uk/discovery/2003/02/cal/), is linked from the
main page (http://www.w3.org/2002/12/cal/).

2: How will we know when we're done?
ACTION libby summarise this discussion into smethign we can discuss
again and maybe agree on in an email

log of the discsussion:

(I'll send a summary email separately)

3: Test data - where's the best place to get it from?

Some ideas for trying to find test data. There is also a list of sample
data on http://www.w3.org/2002/12/cal/

Discussion centred around *motivating examples*:

 18:25:41   <danbri>libby, re broader data, I'd like to come up with
some scenarios (eg.
small business one above) that would motivate folk using RDF cal
structures in their FOAF files.
 18:25:48   <danbri> Then we can just run a crawler to find the data.

- see also (5) below, which worked very well at motivating
discussion on the list

4: Going from RDF to iCal (Ryan Lee)

A discussion of whether better to use XSLT or CWM for going from RDF to
iCalendar, from Ryan Lee who has been working with icalendar files at
w3C. This program is smething Dan Connolly did for Evolution, but other
fapps don;t like it, so it needs improving.


CWM was thought better than XSLT, because the RDF icalendar conversions
are currently syntactic, but might not always be, which woudl make XSLT
parsing impossible except via an XSLT RDF parser like Max Froumentin's:


Moving the python code to the new CWM API is one way the work may

5: Danbri talks about recurrence usecase

see the usecase at:


I would like to use RDF calendar 'recurring events' to represent opening
hours of shops and other services. In particular I'm interested in using
Semantic Web to support local small businesses, by mixing descriptions
their opening hours with other useful information: homepage of shop,
opening hours, contact info, photograph of premises, lat/lang/alt
information, some indication of product lines and individual items for

and the ensuing thread, including icalendar and RDF versions of the
