Exploring Richer Web Content Authoring with CSS and SVG: Five First Public Drafts

2009-03-20: The CSS and SVG Working Groups delivered today five new specifications for public review, aimed at enabling more compelling content creation with open Web technologies. The five drafts are: SVG Transforms 1.0, Part 2: Language, CSS 2D Transforms Module Level 3, CSS 3D Transforms Module Level 3, CSS Animations Module Level 3, and CSS Transitions Module Level 3. SVG Transforms allows two-dimensional objects to be transformed using three-dimensional transformations. CSS 2D Transforms allows elements rendered by CSS to be transformed in two-dimensional space. CSS 3D Transforms extends CSS Transforms to allow elements rendered by CSS to be transformed in three-dimensional space. CSS Animations allow an author to modify CSS property values over time. CSS Transitions allows property changes in CSS values to occur smoothly over a specified duration. The groups are working closely together to make implementing and authoring these features easy and consistent across Web languages. Learn more about the Style Activity and Graphics Activity.

Cross-Origin Resource Sharing Draft Published

2009-03-18: The Web Applications Working Group has published the Working Draft of Cross-Origin Resource Sharing. This document defines a mechanism to enable client-side cross-origin requests. Specifications that want to enable cross-origin requests in an API they define can use the algorithms defined by this specification. If such an API is used on http://example.org resources, a resource on http://hello-world.example can opt in using the mechanism described by this specification (e.g., specifying Access-Control-Allow-Origin: http://example.org as response header), which would allow that resource to be fetched cross-origin from http://example.org.

W3C Invites Implementations of SKOS (Simple Knowledge Organization System) Reference; Primer Also Published

2009-03-17: The Semantic Web Deployment Working Group invites implementation of the Candidate Recommendation of SKOS Simple Knowledge Organization System Reference. This document defines the Simple Knowledge Organization System (SKOS), a common data model for sharing and linking knowledge organization systems via the Web. SKOS—Simple Knowledge Organization System—provides a model for expressing the basic structure and content of concept schemes such as thesauri, classification schemes, subject heading lists, taxonomies, folksonomies, and other similar types of controlled vocabulary. As an application of the Resource Description Framework (RDF), SKOS allows concepts to be composed and published on the World Wide Web, linked with data on the Web and integrated into other concept schemes. The Working Group also published today a Working Draft of SKOS Simple Knowledge Organization System Primer. Learn more about the Semantic Web Activity. (Permalink)

Five First Public Drafts of Web Services Specifications

2009-03-17: The Web Services Resource Access Working Group published five First Public Working Drafts: Web Services Enumeration (WS-Enumeration), Web Services Eventing (WS-Eventing), Web Services Resource Transfer (WS-RT), Web Services Transfer (WS-Transfer), and Web Services Metadata Exchange (WS-MetadataExchange). The first describes a general SOAP-based protocol for enumerating a sequence of XML elements that is suitable for traversing logs, message queues, or other linear information models. The second describes a protocol that allows Web services to subscribe to or accept subscriptions for event notification. The third defines extensions to WS-Transfer that deal primarily with fragment-based access to resources to satisfy the common requirements of WS-ResourceFramework and WS-Management. The fourth describes a general SOAP-based protocol for accessing XML representations of Web service-based resources. The fifth defines how metadata associated with a Web service endpoint can be represented as resources, how metadata can be embedded in endpoint references, and how metadata could be retrieved from a Web service endpoint.
