WOT in RDFa?

(This post is written in RDFa…) To the best of my knowledge, Ludovic Hirlimann‘s PGP fingerprint is 6EFBD26FC7A212B2E093 B9E868F358F6C139647C. You might also be interested in his photos on flickr, or his workplace, Mozilla Messaging. The GPG key details were checked over a Skype video call with me, Ludo and Kaare A. Larsen.

My ’70s Schoolin’ (in RDFa)

I went to Hamsey Green school in the 1970s. Looking in the UK Govt datasets, I see it is listed there with a homepage of ‘http://www.hamsey-green-infant.surrey.sch.uk’ (which doesn’t seem to work). Some queries I’m trying via the SPARQL dataset (I’ll update this post if I make them work…) First a general query, from which I […]

WordPress trust syndication revisited: F2F plugin

This is a followup to my Syndicating trust? Mediawiki, WordPress and OpenID post. I now have a simple implementation that exports data from WordPress: the F2F plugin. Also some experiments with consuming aggregates of this information from multiple sources. FOAF has always had a bias towards describing social things that are shown rather than merely […]

WordPress, TinyMCE and RDFa editors

I’m writing this in WordPress’s ‘Visual’ mode WYSIWYG HTML editor, and thinking “how could it be improved to support RDFa?” Well let’s think. Humm. In RDFa, every section of text is always ‘about’ something, and then has typed links or properties associated with that thing. So there are icons ‘B’ for bold, ‘I’ for italics, […]

Syndicating trust? Mediawiki, WordPress and OpenID

Fancy title but simple code. A periodic update script is setting user/group membership rules on the FOAF wiki based on a list of trusted (for this purpose) OpenIDs exported from a nearby blog. If you’ve commented on the blog using OpenID and it was accepted, this means you can also perform some admin actions (page […]

Remote remotes

I’ve just closed the loop on last weekend’s XMPP / Apple Remote hack, using Strophe.js, a library that extends XMPP into normal Web pages. I hope I’ll find some way to use this in the NoTube project (eg. wired up to Web-based video playing in OpenSocial apps), but even if not it has been a […]

Streaming Apple Events over XMPP

I’ve just posted a script that will re-route the OSX Apple Remote event stream out across XMPP using the Switchboard Ruby library, streaming click-down and click-up events from the device out to any endpoint identified by a Jabber/XMPP JID (i.e. Jabber ID). In my case, I’m connecting to XMPP as the user xmpp:buttons@foaf.tv, who is […]

Apple Remote events – a quick howto

Anyone who has recently bought an Apple computer probably has one or more Apple Remotes. I have been learning how to access them. Conclusion: iremoted does 95% of what you probably need, and the discussion over on cocoadev.com tells you more than you probably wanted to know. My experiments are written up in a corner […]

Local Video for Local People

OK it’s all Google stuff, but still good to see. Go to Google Maps, My Maps, to find ‘Videos from YouTube’ listed. Here’s where I used to live (Bristol UK) and where I live now (Amsterdam, The Netherlands). Here’s a promo film of some nearby art installations from ArtZuid, who even have a page in […]

Quick clarification on SPARQL extensions and “Lock-in”

It’s clear from discussion bouncing around IRC, Twitter, Skype and elsewhere that “Lock-in” isn’t a phrase to use lightly. So I post this to make myself absolutely clear. A few days ago I mentioned in IRC a concern that newcomers to SPARQL and RDF databases might not appreciate which SPARQL extensions are widely implemented, and […]

Getting started with Mozilla Jetpack for Thunderbird (on OSX)

A few weeks ago, I started to experiment with Mozilla’s new Jetpack extension model when it became available for Thunderbird. Revisiting the idea today, I realise I’d forgotten the basic setup details, so am recording them here for future reference. I found I had to download the source from the Mercurial Web interface, rather than […]

Mirrors and Prisms: robust site-specific browsers

Mozilla (amongst others, see Chris Messina’s writeup of the trend, also Matt’s) have been exploring site-specific browsers through their Prism project. These combine aspects of the Web and Desktop environments, allowing you to have a desktop app tuned for browsing just one specific Web site. Prism is an application which, when run, will generate new […]

Wolfram Alpha Interview

An interview with Xiang Wang of Wolfram Research in China, by Han Xu (Collin Hsu) of W3China fame. Interesting excerpt: Q: Since Wolfram|Alpha is dubbed ‘smarter’ than traditional search engines, I wonder how much AI techniques are actually employed in the system? How is inference done? What is the provenance of each fact/claim? And what […]

What kind of Semantic Web researcher are you?

It’s hard to keep secrets in today’s increasingly interconnected, networked world. Social network megasites, mobile phones, webcams and  inter-site syndication can broadcast and amplify the slightest fragment of information. Data linking and interpretation tools can put these fragments together, to paint a detailed picture of your life, both online and off. This online richness creates […]
