UPDATE: Oliver Roup has published updated code that uses the builtin XPath processor in JDK 1.5
Some emails and comments on Screenscraping HTML with TagSoup and XPath alerted me to the fact that the example I gave on that page has gone out of sync with the current release of JDOM and no longer works. I’ve reworked the example using Xalan 2.5.

Having connected my GPS unit to my laptop, it was time to dump the data off into a usable RDF model.

A short note to fill in for something I couldn’t find via google on getting a PL2303-based serial-USB adapter to work with linux…

In preparation for a TiVoBot that I’m planning to write as a wrapper for scheduling digital WinTV recordings, I’ve been looking at TV listings data produced by tools from the XMLTV project. I started out using the XML directly and storing it using Berkeley DB XML but soon found (like most of my projects) that I’d be happier if the data was expressed as an RDF model.

After seeing Richard Clamp’s excellent talk at a london.pm techmeet on using Ericsson phones as remote controls I went away to code something similar (but less fully-functioned) in python for my own use. My code plugs into the Twisted framework and listens for phone keypress events. It uses the AT commands defined in an Ericsson PDF for the R320 phone, and it works with my T610.

Today we relaunched The Daily Chump, a multi-author IRC-based blog, with a shiny new look and a new feature: the chumpologica. This is a webpage (and RSS 1.0 feed) that aggregates entries from blogs written by regular contributors to the Chump. It’s built using about 150 lines of python and takes its configuration from a FOAF file.
Update: I’ve now packaged and released this project as a proper distribution.

OpenOffice’s vector-drawing app has a very nice Visio-like ‘connector’ tool that can link objects together with lines. It’s very easy to put together labelled directed graph diagrams and have the lines re-flow as you move the nodes around. It also has a well-documented XML file format, which got me thinking that graph drawings could be converted into RDF automatically. I wrote some python code to read in OO files and print out n-triples.

I gave a developer-oriented version of my semantic web “photos and metadata” talk at www2003 developers day. The slides are available online and there are a bunch of demos to look at.

After such an intense day of note taking and a very entertaining evening bowling with the guys from ILRT on day 1, I didn’t manage to take proper notes on yesterday’s sessions. I’ll try to fill in some detail during today.

I’m at www2003 in Budapest, Hungary for the rest of the week. I’m not much of a note-taker but I’ll probably jot a few things down here. Good wireless coverage in the conference venue. See also day 2.
