3 Publications by The Permissions and Obligations Expression WG

The Permissions & Obligations Expression (POE) Working Group has published the First Public Working Drafts for the ODRL Information Model and the ODRL Vocabulary & Expression. These FPWDs provide a flexible and interoperable information model, vocabulary, and encoding mechanisms for describing statements about digital content usage. The deliverables are based on the previous reports created by the W3C ODRL Community Group and form the baseline for future enhancements by the POE WG.

In addition, the POE WG has published the Use Case and Requirements Note. These Use Cases will be reviewed and analyzed further into detailed requirements. The POE WG is calling for wider community feedback and contributions to the set of Use Cases to further enhance and improve the ODRL permissions and obligations expression language.

The XML Processing Model Working Group has published two Group Notes:

XML Inclusions (XInclude) Version 1.1 Note Published

The XML Core Working Group has published a Group Note of XML Inclusions (XInclude) Version 1.1. This document specifies a processing model and syntax for general purpose inclusion.

First Public Working Draft: Pointer Events Level 2

The Pointer Events Working Group has published a Working Draft of Pointer Events – Level 2. The features in this specification extend or modify those found in PointerEvents, a W3C Recomendation that describes events and related interfaces for handling hardware agnostic pointer input from devices including a mouse, pen, touchscreen, etc. For compatibility with existing mouse based content, this specification also describes a mapping to fire DOM-LEVEL-3-EVENTS Mouse Events for other pointer device types.

First Public Working Draft: Remote Playback API

The Second Screen Presentation Working Group has published a Working Draft of Remote Playback API. This specification defines an API extending the HTMLMediaElement that enables controlling remote playback of media from a web page. It aims to make remote playback devices such as connected TVs, projectors or audio-only speakers, available to the Web and takes into account playback devices that are attached using wired (HDMI, DVI, or similar) and wireless technologies (Miracast, Chromecast, DLNA, AirPlay, or similar).

Time Ontology in OWL Draft Published

The Spatial Data on the Web Working Group, a joint endeavor by W3C and OGC, has published an updated version of the Time Ontology in OWL, first published by the Semantic Web Best Practices and Deployment Working Group in September 2006. The ontology has been in widespread use since that time despite two particular problems: the uncertain status of the work and its lack of support for calendar systems other than the Gregorian calendar. The SDW WG is addressing the first issue by taking the specification through the full standards process of both W3C and OGC. The second problem is fully resolved in the new draft, so that the Time Ontology is able to support any Temporal Reference System. Further requirements identified by the WG are also being addressed.

W3C Invites Implementations of Web Annotation Protocol

The Web Annotation Working Group invites implementation of the Candidate Recommendation of Web Annotation Protocol. Annotations are typically used to convey information about a resource or associations between resources. Simple examples include a comment or tag on a single web page or image, or a blog post about a news article. The Web Annotation Protocol describes the transport mechanisms for creating and managing annotations in a method that is consistent with the Web Architecture and REST best practices.
