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, […]

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 […]

How the Web works

How it works: The Web Originally uploaded by danbri Or, “but what do all those links mean?” Based on the 1994 slides by TimBL which inspired the SWAD-Europe graphics and shirt. The twist here is just an emphasis that the giant global graph is a graph of idiosyncratic claims, and only sometimes do we all […]

Open social networks: bring back Iran

Three years ago, we lost Iran from Internet community. I simplify somewhat, but forgivably. Many Iranian ISPs cut off access to blogs and social networking sites, on government order. At the time, Iran was one of the most active nations on Orkut; and Orkut was the network of choice, faster than the then-fading Friendster, but […]

Microblogs and the monolingual

Twitter-like microblogging seems a nice granularity for following thoughts expressed in languages you don’t speak. In 1988 I passed my French language GCSE exam; it’s been downhill all the way since. A year ago in Argentina, I got to the stage where I could just about express myself in Spanish. But it’s been fading. Nevertheless […]

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 […]

Symbol languages and the Semantic Web

OK so I just stumbled upon this… …via Jonathan Chetwynd’s ever-inventive and SVG-happy Peepo.com. The “Car Bomb in Baghdad” story is from a site created by Widgit Software, and explains itself as follows: Symbolworld has been set up to provide a web site with material suitable for symbol readers of all ages. The internet is […]

GIS and Spatial Extensions with MySQL

GIS and Spatial Extensions with MySQL. MySQL 4.1 introduces spatial functionality in MySQL. This article describes some of the uses of spatial extensions in a relational database, how it can be implemented in a relational database, what features are present in MySQL and some simple examples. I’m hoping to understand the commonalities between this and […]

Four notions of “wishlist” for FOAF

After the recent SWAD-Europe meeting on ImageDescription techniques, I made some scribbled notes in a bar on different notions of “wishlist” that might make sense to use with FOAF. At the ImageDescription meeting we talked a lot about the difficulty of scoping such technical activities, since problem spaces overlap in ways that create opportunities and […]
