Generating events data from weblogs

This is an experiment to see if we can usefully use this weblog for events. Currently creating RDFiCal events is time-consuming and so doesn't get done.

The idea here (originally trialled with the #rdfig chump, http://rdfig.xmlhack.com), is that a service parses a particular format of text and converts its parts to RDFiCal. This was inspired by Danbri, who wrote

XML 2003, Dec 7-12th, Pennsylvania Convention Centre, Philadelphia PA, USA.

As the title of the chump entry he created to talk about going to the conference.
So if it's that easy, maybe people would use the chump or their blogs to create event information.

I spent a day or so writing a perl script that grabs the item url and title from an RSS 1.0 feed, and parses the title into

title of event, start and end dates of event, location, location, location....

The start and end dates can be like this:

23-23rd May 2003
23-23 May 2003
23 June -23 July 2003
May 22-June 23rd 2003
2003-12-15 - 2003-12-16

- it's meant to be very loose.

It then uses a city lookup service to try and work out the GPS locations of the location.

The #rdfig 'chump' differs from many blogs as the url that appears in the items in the rss 1.0 channel is the url of the thing of interest, not the url of the weblog entry as in movable type and so on. Therefore it helps to be able to specify which tags you expect the information to be in. In the chump case it's <item rdf:about= for the url, and <title> for all the rest. For movable type where there's no obvious place to put the url, the format is

title of event, start and end dates of event, location, location, location, url

The url is optional. In both formats it will only generate data if it can work out what the start and end date is at least, plus a title. So you need to have title, dates.

For entries on the chump, urls like this one, generate an RDFiCal file if they can and also save it here.

For the esw weblog, this url generates the RDFiCal from the index.rdf of this weblog and saves it here.

iCalendar to RDFical: a Semantic Web vocabulary created with community process-lite

Libby Miller gave an invited seminar at the University of Southampton's Intelligence, Agents and Multimedia group (IAM) on 3rd November 2003. She talked about Calendaring and the Semantic Web to a group of about 40 researchers and students. More information is available: RDF calendar workshop, including usecases, RDF calendar wiki, RDF calendar documentation, RDF Calendar workspace, RDF Calendar mailing list. Categories Calendar

Latest RDF calendar irc meeting

The latest follow-up to the SWAD-E calendar workshop was at 6pm GMT 2002-01-15 (agenda, logs, participants). Developers from Mozilla calendar, OpenCal and apple iCal, as well as W3C and lots of other interested parties came along. We talked about xcal, tests, interoperability, openCAP and CAP in general. The RDF calendar workspace is used for RDF tests and various links, and previous chats and logs. The next chat is Wednesday 22nd January 2003 at 5pm GMT.
