Archive.org TV metadata howto

The  following is composed from answers kindly supplied by Hank Bromley, Karen Coyle, George Oates, and Alexis Rossi from the archive.org team. I have mixed together various helpful replies and retro-fitted them to a howto/faq style summary. I asked about APIs and data access for descriptions of the many and varied videos in Archive.org. This guide should […]

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 […]

Google Visualization API – external datasources

You can now wire-in external datasources to Google’s Visualization API (see announcement). Previously, you had to populate the various UI widgets from Javascript or from Google-hosted datasources (such as spreadsheets). Their examples page shows some of the possible visualizations. My favourite are the Motion Charts, based on work acquired from the wonderful GapMinder project.

Mozilla Ubiquity

The are some interesting things going on at Mozilla Labs. Yesterday, Ubiquity was all over the mailing lists. You can think of it as “what the Humanized folks did next”, or as a commandline for the Web, or as a Webbier sibling to QuickSilver, the MacOSX utility. I prefer to think of it as the […]

OpenSocial schema extraction: via Javascript to RDF/OWL

OpenSocial’s API reference describes a number of classes (‘Person’, ‘Name’, ‘Email’, ‘Phone’, ‘Url’, ‘Organization’, ‘Address’, ‘Message’, ‘Activity’, ‘MediaItem’, ‘Activity’, …), each of which has various properties whose values are either strings, references to instances of other classes, or enumerations. I’d like to make them usable beyond the confines of OpenSocial, so I’m making an RDF/OWL […]

Imagemap magic

I’ve always found HTML imagemaps to be a curiously neglected technology. They seem somehow to evoke the Web of the mid-to-late 90s, to be terribly ‘1.0’. But there’s glue in the old horse yet… A client-side HTML imagemap lets you associate links (and via Javascript, behaviour) with regions of an image. As such, they’re a […]

Ruby client for querying SPARQL REST services

I’ve started a Ruby conversion of Ivan Herman’s Python SPARQL client, itself inspired by Lee Feigenbaum’s Javascript library. These are tools which simply transmit a SPARQL query across the ‘net to a SPARQL-protocol database endpoint, and handle the unpacking of the results. These queries can result in yes/no responses, variable-to-value bindings (rather like in SQL), […]

HTML Imagemap authoring tool for MacOSX?

I’ve searched around in vain for one. I want to annotate my FOAF spec diagram with mouseover text and links into the documentation. Most of the tools I find are a decade or more old, or pay-to-play. I remember the Gimp image editor can do imagemaps, but it crashes on startup on my MacBook. I […]
