Semantic Desktop in KDE 4.0 on Linux- May 27, 2008 A new Semantic Web Case Study has just been published: KDE 4.0 Semantic Desktop Search and Tagging. Essentially, Semantic Web technologies (RDF, RDFS, OWL) are used as a backend metadata architecture in KDE 4.0 to tag, comment, annotate, etc, all files under Linux regardless of their file format, and to initiate corresponding search actions. In other words, millions of LinuxKDE users will become Semantic Web technology users without necessarily knowing it The development was done by the...http://www.w3.org/QA/2008/05/semantic_desktop_in_kde_40_on.html Open Standards Interoperability- May 20, 2008 Recent blog posts about Open Standards from Paul Fremantle are being commented on different blogs. Why open standards and interoperability are subtly different, May 10, 2008 Open Source versus Open Standards - May 13, 2008 He said: My own criteria for interoperability is that there are "tested independent implementations". This means that different groups have looked at the spec, worked through it and written code. And then they have taken these implementations and tried them against...http://www.w3.org/QA/2008/05/open-standards-interoperability.html My Arms Are WAI Too Short- May 15, 2008 ok. The title is a bit of a stretching. WAI stands for Web Accessibility Initiative. My arms are really becoming too short. I love reading. I have 1h30 of commuting in the morning by train and bus, and the same in the evening. I love this precious time in the train that I use for reading. For the last 6 months, I have an issue. I need to put my book farther and farther from me to have a comfortable reading. Yeah! you can say it, I'm getting old. sigh The WAI-AGE project has just published a...http://www.w3.org/QA/2008/05/web-accessibility-older-users.html SVG + XMPP = whiteboard- May 14, 2008 A whiteboard is an online shared space where two (or more) distant persons can edit the same document in real time. It creates an instant social interaction around a document. I have spotted on Ferris at least two projects which are (or in the process of) using a combination of SVG and XMPP for creating whiteboards. Coccinella. The Mats Bengtsson said recently: "The canvas widget in TclTk is way too limited to use as a basis to implement SVG support on the scripting level. For some time I...http://www.w3.org/QA/2008/05/using-svg-for-whiteboard.html We, Robots Like Music Too- May 14, 2008 In R.U.R. (Rossums Universal Robots) by Karel apek, Dr. Hellman, Psychologist-in-Chief, says: Dr. Hellman (at door, left) Music is a wonderful thing, you know. You should have been listening. There's something ennobling about it, soothing We like it too. The Web has given a unique opportunity for everyone to link data, to share, to reuse and create. BBC is one of my favourite source of news. I like their site and I like their mission statement. Tom Scott (BBC Radio Labs) says in a...http://www.w3.org/QA/2008/05/bbc-sharing-linked-data.html Improving access to Government through better use of the Web- May 12, 2008 Seventeeth months ago, the W3C Team started to look into a somewhat new area for W3C, eGovernment. You know, the way in which government agencies, departments and the like are using technology (mainly the Web) to develop services and communicate with their citizenry, the industry and between themselves. Why Well, the massive use of Web technology to develop and deploy those services already made the Web a crucial tool for eGovernment. We have learned quite a number of things so far. Services..http://www.w3.org/QA/2008/05/better-web-access-to-government.html Syntax for ARIA: Cost-benefit analysis- May 7, 2008 Syntax for ARIA: Cost-benefit analysis Henry S.

The article unfortunately mixes unicode and utf-8 as it has been noticed by David Goodger in Unicode misinformation. But the really interesting bit is the growth of utf-8 on the Web. These data should be interesting for the development of http, html 5 and validators. graph from Google.http://www.w3.org/QA/2008/05/utf8-web-growth.html Vertical Layouts for Canvas Text (CJK)- May 2, 2008 I have noticed a discussion (I have cut some parts for readability) about vertical layout for text from the participants of the HTML WG. <Hixie> ok for canvas text my proposal is: <Hixie> drawHString(x, y, maxWidth, textAlign, s); and drawHString(x, y, maxHeight, textAlign, s); <Hixie> drawVString(...) for the second one <Lachy> what's the difference between them drawVString for vertical stings where the letters are stacked on top of each other, and...http://www.w3.org/QA/2008/05/canvas-text-and-cjk.html How to add RDF information to a page using RDFa- May 1, 2008 The Semantic Web Activity home page has a number of information that might be of interest for the Semantic Web (eg, for data integration). These include: references to existing recommendations, talks on the subject made by working group members or the W3C staff, references to active groups, etc. Ie, it sounds like a good idea to make these available in RDF, too. Of course one could achieve that by publishing two files: http:www.w3.org2001swOverview.html for the HTML version and a separate...http://www.w3.org/QA/2008/05/using_rdfa_to_add_information.html |
