From 38be0d13830efd2d98281c645c3a60afe05ffece Mon Sep 17 00:00:00 2001 From: Qt by Nokia Date: Wed, 27 Apr 2011 12:05:43 +0200 Subject: Initial import from the monolithic Qt. This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12 --- examples/xml/README | 40 + examples/xml/dombookmarks/dombookmarks.pro | 20 +

New eGovernment Activity to Help Improve Government through Better Use of the Web

+

Crowd scene

+

2008-06-03: W3C launches today a new forum for governments, citizens, researchers, and other stakeholders to investigate how best to use Web technology for good governance and citizen participation. "Open Standards, and in particular Semantic Web Standards, can help lower the cost of government, make it easier for independent agencies to work together, and increase flexibility in the face of change," said Tim Berners-Lee, W3C Director. W3C invites participation in the new eGovernment Interest Group, which is open to the public. The group will identify best practices and guidelines in this area, document where current technology does not adequately address stakeholder needs, and suggest improvements via the standards process. Read the W3C eGovernment FAQ and press release, and learn more about the W3C eGovernment Activity. (Permalink)

Two Group Notes Published About Semantic Web and Life Sciences

2008-06-05: The Semantic Web Health Care and Life Sciences Interest Group has published two Group Notes: A Prototype Knowledge Base for the Life Sciences and Experiences with the conversion of SenseLab databases to RDF/OWL. The former describes a prototype of a biomedical knowledge base that integrates 15 distinct data sources using currently available Semantic Web technologies including RDF and OWL. The Note outlines which resources were integrated, how the knowledge base was constructed using free and open source triple store technology, how it can be queried using SPARQL, and what resources and inferences are involved in answering complex queries. While the utility of the knowledge base is illustrated by identifying a set of genes involved in Alzheimer's Disease, the approach described here can be applied to any use case that integrates data from multiple domains. The second document describe the experience of converting SenseLab databases into OWL, an important step towards realizing the benefits of Semantic Web in integrative neuroscience research.

W3C Launches Group to Help Bridge the Digital Divide

Phone bikes2008-05-27: As part of the growing set of W3C initiatives related to social development, W3C invites participation in the new Mobile Web for Development (MW4D) interest Group, chartered to explore the potential of mobile technology to help bridge the digital divide. "We need to solve important challenges, such as lack of standards in end-user devices, network constraints, service cost, issues of literacy, and an understanding of the real information needs of rural communities," said Ken Banks, kiwanja.net, who Chairs the group. "To do so requires an multidisciplinary approach, a step we take through the creation of this new group." Read more in the press release. This launch is part of W3C's Mobile Web Initiative (MWI), which aims to identify and resolve challenges and issues of accessing the Web when on the move. This work takes place under the auspices of the European Union's 7th Research Framework Programme (FP7), part of the Digital World Forum project. (Photo credit: Stéphane Boyera. Permalink)

Last Call: CURIE Syntax 1.0

2008-05-08: The XHTML2 Working Group has published the Last Call Working Draft of CURIE Syntax 1.0, which outlines a syntax for expressing URIs in a generic, abbreviated syntax ("Compact URI"). The specification targets language designers who need a mechanism to permit the use of extensible value collections. Any language designer considering the use of QNames in attribute values should consider instead using CURIEs, since CURIEs are designed for this purpose, while QNames are not.
