sbp: Heh, "pronounced 'exotickle'"
 
dajobe: It has come to this, plugging my own stuff
 
dajobe: now comes with an libwww-based RDF parser for adding RDF statements
 
sbp: From the overview, "This is a draft of an RDF API provided for a public discussion. The API defines interfaces for parsing (org.w3c.rdf.syntax) and accessing RDF models as sets of statements (org.w3c.rdf.model)."
 
 
dajobe: not yet released at this date
 
dajobe: my thoughts on scripting and other language support for Redland
 
danbri-out: A proposal for a simple RDF vocabulary that provides some basic facilities to support the extraction of structured RDF data from arbitrary HTML, XHTML and pseudo-HTML textual content.
danbri-out: "SWIPE can be used to support simple screenscraping and meta-search applications, or extended (like RSS) to more richly
danbri-out: ... describe interfaces to Web data services."
 
danbri-out: Scraping Exchange (a proposal for an RDF-based screenscraper format)
danbri-out: More than that actually, 'Site Layout Format', gets into robots.txt / URISpace territory.
 
 
danbri: "This document explores some examples based around the idea of extending RSS using RDF-based modularisation, and then querying the resulting data in ways that exploit those extensions."
danbri: Extended RSS could bypass a lot of the heavierweight XML B2B stuff, in terms of actually making money for folk on the Web. It's cheap to produce and consume, and doesn't involve protocols or standards committees.
 
libby: second go at rdfpath squish implementation
libby: still not right....
libby: trying to collect together some rdfpath tests
 
danbri: "The purpose of examplotron is to use instance documents as a lightweight schema language-- eventually adding the information needed to guide a
danbri: ... validator in the sample documents."
 
hector: Read this before reading the HailStorm propaganda.
 
danbri: "Example Scenario:401: Oh Yeah? Prove you have access! ... The Semantic Web will allow us to model social processes, making facts and rules available for sharing between heterogeneous implementations of those social processes.For example, consider access to the W3C web site. A portion of the W3C web site is confidential to the W3C Membership. Traditional web server facilities allow us to create a w3c-member group, issue accounts that
danbri: But this is a poor model of the actual social process, and the W3C spends a lot of administrative resources bridging the gap: the right to access the member confidential portions of the W3C web site is actually granted to any W3C Member representative, and each W3C Member organization has a distinguished Advisory Committee Representative (AC Rep) who has the right to appoint other representatives from his/her organization (...)"
danbri: "In the Semantic Web we can represent the whole range of policies as logical assertions using classical logic with quoting and some axioms about digital signatures. Wereplace the fixed structure of groups and accounts in the web server with a component that verifies assertions of the form ..."
danbri: "Kwebmaster assures "hasAccess(Krequestor, pageID)"
 
danbri: An Introduction to Microsoft Hailstorm (whitepaper), March 2001.
danbri: I find the problem statement in the hailstorm paper pretty accurate. Whether there's technology to solve it is another question! (still reading...)
danbri: use case: "For instance, with HailStorm services, booking a flight
danbri: ... using an online travel reservation service becomes much simpler because with the user?s consent, the travel service automatically
danbri: ... access the user?s preferences and payment."
danbri: IMHO a travel reservation service should be able to read my homepage to find out that I'm vegetarian. Sensitive information is more interesting of course...
hector: "HailStorm will make it easier to integrate the silos of information that exist today." That sentence is enough to condemn it.
AaronSw: attempt to do Hailstorm decentralized (perhaps w/ RDF?)
 
danbri: In conjunction with the Joint German/Austrian Conference on AI
danbri: "This workshop
danbri: The call cites applications such as "data mining, medicine, natural language, process engineering, disaster management and temporal and spatial reasoning."
danbri: Also features invited presentation from Ian Horrocks (of DAML+OIL fame :)
danbri: "This workshop intends to gather researchers as well as practitioners who are interested in description logics and their applications." (announced on [DL] list 2001-03-25)
dajobe: (test)
 
bitsko: (found by Niel @ MonkeyFist.com)
bitsko: Experimental!!!
bitsko: "The ISBNdb project proposes to accomplish for books what the CDDB project accomplished for Compact Disks. The ISBN Database will provide a central collection point for identifying information for books. The interface for extracting and inserting
bitsko: information will be standardized and publicly released, and no charge will be made for such access."
bitsko: He's got it all wrong, of course (WDDX). it should just be http://www.isbndb.com/ISBN/0-201-71091-9, and back plops RDF.
AaronSw: Shoot, I had that idea a year or two ago.
AaronSw: I was going to integrate it with isbn.nu
AaronSw: Maybe someday...
 
edd: DanBri is RDF Wizard
 
danbri: Idea is to annotate prose rather than just write blocks of RDF, ie allow a freeform storytelling style of XHTML that also mentions a bunch of RDF-happy facts.
 
jhendler: download DAML (and thus RDFS) to your Palm for browsing
 
danbri: Web services on the cheap. An API of "tell me more about X", a la PICS label bureau.
 
danbri: Many of these .xul examples can be tested directly in Mozilla/Netscape6.
 
Contemporary definition of a "standard"
edd: When a good idea is had by someone on a mailing list, it's a good idea.
edd: When it's had by someone in a corporation, it's the next "open standard"
edd: cd. UDDI, WSDL, etc.
edd: More review, more review, more review.
