  • orchestration

  • choreography

  • conversation

The Semantic Web and the "History" Technique - Sandro mind-dumps some ideas for handling this kind of situation:
"Imagine that you know Joe is wearing a red hat, but you say only, 'Someone is wearing a red hat'. Now Joe takes it off. Saying, 'Someone is no longer wearing a red hat' is not right at all -- that might have been true before (lots of people are no longer wearing red hats), and it doesn't even contradict the notion that Joe is still wearing a red hat."

KnownSpace Helium - "...represents the latest incarnation of the open-source software built in Java to serve as a common platform for worldwide research and collaboration in artificial intelligence, networking, and user interfaces."

The docs seem to take a view from the model/representation in the app - Simpletons, Entities etc - it would be interesting to see how well this maps to RDF

Ingenta - "The most comprehensive collection of academic and professional
publications available for online, fax and Ariel delivery."

seems largely (all?) pay-for, but a heck of a range of material

It also happens to be Leigh Dodd's daytime haunt, and his XML-oriented
Eclectic weblog is back in action. He's also the foaf:Person responsible for the FOAF-a-matic.

Content Syndication with RSS - book by Ben Hammersley "...for web developers who want to offer XML-based feeds of their content, as well as those developers who wish to use the content that other people are syndicating."

I've not seen it yet (Xmas list), but if it's anything like Ben's blog it'll be a rich seam.

Don't forget when your domain names expire!
I did, and it looks like I've just lost the main domain name I've been using for the past few years, (isacat.net). It's now occupied by a 'search engine' that appears to specialise in casinos.

The registrar had my old Lanka address, so I didn't get any notification, first I knew was when I got a mail from someone saying the couldn't find something on the site.

I've also been using danny@isacat.net as an alternative address, routed in case there are problems with my main address danny666 at virgilio.it.

Suggestions for damage limitation welcome!

Repeat post of this - I just realised that Blogger was using the isacat name in the ftp, so my last half dozen posts have only just come through...

...meanwhile Evan Williams of Blogger blogs this page. Funny old world, innit...

Information Foraging - Cognitive Models for Web Design "... information foraging is an exaptation of food foraging mechanisms, therefore models of optimal foraging theory developed by anthropologists and ecologists in the study of food foraging will help us understand foraging behavior in consumers of information."

"exaption"? did they make that up?

Amaya 7.0 released. The W3C's testbed WYSIWYG browser now uses Dave Beckett's Raptor parser for RDF - presumably the primary use will be for annotations (via Annotea) but it should open the door to a lot of other potential apps. SVG support has also been increased, along with load of other enhancements.

For W3C, it's a question of semantics - Tech News - CNET.com
"It's not artificial, and it's not intelligent," said Eric Miller, activity lead for the W3C's Semantic Web Activity. "The conceptual models behind RDF are predicated on work in the digital library community. You can think of this as a common framework that supports thesaurus, taxonomies and classification schemes."

Faceted Metadata Search - Search Tools Report
Discusses problems of field-based (parametric) search & full-text, then goes on to say: "...good solution to these problems involves exposing the facets in dynamic taxonomies, so that the search user can see exactly the options they have available at any time. They can switch easily between searching and browsing, using their own terminology for search while recognizing the organization and vocabulary of the data.
"

Existing engines that use this approach include :
Endeca, i411 and Teapot.
