"Designed as a one minute overview of the differences and similarities of RDF and XML, this illustration discusses approximately a dozen key
points in language that can be understood by managers and techies alike.

XQuery and XPath Full-Text [search] Requirements W3C Working Draft 14 February 2003

The Globus Project "...is developing fundamental technologies needed to build computational grids. Grids are persistent environments that enable software applications to integrate instruments, displays, computational and information resources that are managed by diverse organizations in widespread locations." With Globus Toolkit 3.0 Alpha Release.

Real World Annotations: Manywhere Places (Russell Beattie) neat idea, using a GPS phone to annotate a real place.
Not unlike The Accessible Planet.

Distributed Persistent Collaboration: A Start-Up Scenario and Strategy
for Acquiring Resources

Interoperable Language Standard (ILS) - Call for participation.
"Proposal: A standard for marking up typical electronic textual content, and referencing textual content, so that it's meaning becomes unambiguous, translatable and machine-readable." (using RDF and XML)

OpenCyc release 0.7 for Linux and Windows
"OpenCyc is the open source version of the Cyc(r) technology, the world's largest and most complete general knowledge base and commonsense reasoning engine."

RDF Schema Info - 3000 url (so far) index - spiders the web for RDFS, searchable.

A Simplified Model for Facet Analysis (Dr. Louise Spiteri)

NewsMonster (first beta release) - "The cross-platform weblog manager with a brain!"
Sophisticated RSS reader, "... incorporates an advanced reputation system to prevent spam and discover and inform you of important news."
RDF-backed - a true semantic web application.

Burningbird: By their own words shall they be known

Shelley's added the capability to her blog to show all the comments from any particular person, "Talkback". Apart from being a neat little gadget, I think it's interesting the way a query is made using the URL that people submit with their comments. Very SemWeb.

XML Topic Maps Congress April 10th, Germany

PersonalProxy

another one, graciously pointed out by 0xDECAFBAD, unfortunately the information seems pretty well hidden...

Controlled Vocabulary
" your site for information on Keyword, Hierarchical Classification, Thesauri, Taxonomy and Subject Heading systems used to describe images in databases (Thesaurus, facet classification, hierarchy)"
Not a great deal there, but some potentially useful links.

Agent Frank - a proxy server with RDF capability "The goal of Agent Frank is to be a personal intelligent intermediary and companion to internet infovores during their daily hunter/gatherer excursions."
Java.

I saw this in my feed from 0xdecafbad, but didn't realise the RDF bits were in there until seeing it on #rdfig. Looking further, I didn''t realise it was Java (I thought is was Python) so it might well be useful to me...

Sight
a code generator set to create a user-defined system of Web robots, realising arbitrary workflow.

good day for gems on Erik's Weblog

Google Buys Pyra (makers of 'Blogger')

Interesting to see what (if anything) develops - Sergey Brin of Google seemed to miss the whole idea of the Semantic Web in his "...putting angle brackets around things is not a technology..." statement, so I don't think we're talking Semantic Blogging here. If there is some kind of Googling of Blogger then expect to see something along the lines of John Robb's k-log idea, where the knowledge is maintained in regular blogs and primarily retrieved through traditional plain text search techniques such as those used in Google. Such a system won't know the difference between Sambuca (the drink) and Sambuca (our cat) or Sambuca (the town in which our cat was born).
