Web Tracking and Privacy Focus of W3C Workshop

03 March 2011 | Archive

Tracking (e.g., for behavioral advertising) has come to the forefront recently as part of the overall Web privacy conversation in the broader Web and policy community. Several software vendors (including Microsoft, Mozilla, and Google) are offering measures that are intended to permit users to opt out of this tracking, or to prevent tracking by Web sites that are known to engage in these practices. Similar technology is deployed in a number of plugins (including NoScript, AdBlock plus, TACO, and PrivacyChoice). As part of ongoing efforts in the area of user privacy on the Web, W3C is organizing a Workshop on Web Tracking and User Privacy, 28-29 April 2011 in Princeton, New Jersey (USA). Topics are likely to include: whether a do not track proposal is advisable or other means might accomplish the same goals; benefits and challenges of browser-bade approaches; other approaches to better user privacy in the face of frequent online tracking. Anyone may participate in this Workshop; a position paper is required and space is limited. Position papers are due 25 March 2011 but expressions of interest sooner than that are appreciated. Many thanks to the Center for Information Technology Policy at Princeton University for hosting the meeting. Please see the the Call for Participation for further details.

W3C Invites Implementer Feedback on XML Security 1.1 Specifications

04 March 2011 | Archive

The XML Security Working Group published four Candidate Recommendations today: XML Signature Syntax and Processing 1.1, XML Encryption Syntax and Processing 1.1, XML Security Generic Hybrid Ciphers, and XML Signature Properties. XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere. As companion documents, the Working Group has released new Working Drafts of XML Security 1.1 Requirements and Design Considerations and XML Security RELAX NG Schemas.

To address patent disclosures related to the XML Signature 1.1 and XML Encryption 1.1 specifications, W3C has chartered a Patent Advisory Group. Learn more about W3C's Security Activity.

W3C Launches Patent Advisory Group for XML Signature and XML Encryption

Public comments regarding these disclosures may be sent to (with public archive). Learn more about Patent Advisory Groups.

W3C Note Published: Describing Linked Datasets with the VoID Vocabulary

03 March 2011 | Archive

The Semantic Web Interest Group has published a Group Note of Describing Linked Datasets with the VoID Vocabulary. Semantic Web and other technologies have made it easy and beneficial to publish and share datasets. When someone wants to select a dataset, one of the fundamental questions is, what does it offer? There are datasets such as DBpedia that cover quite a range of topics, whereas there are others that only talk about a certain domain (books, places, etc.). VoID provides a bridge between the publishers and users of datasets. VoID addresses a variety of needs, ranging from data discovery to cataloging and archiving of datasets. Most importantly, VoID helps users find the right data for their tasks. Today's publication provides advice about deployment of dataset descriptions and discusses the discovery as well.

Web Notifications First Draft Published

01 March 2011 | Archive

The Web Notification Working Group has published the First Public Working Draft of Web Notifications. This specification provides an API to generate simple notifications to alert users outside of the web page. It does not specify exactly how a user agent should display these notifications; the best presentation depends on the device where the user agent is run. When this specificiation refers to displaying notifications on the "desktop", it generally refers to some static display area outside the web page, but may take several forms, including a corner of the user's display, an area within the chrome of the user agent, or the "home" screen of a mobile device.

Best practices for creating MMI Modality Components Note Published

01 March 2011 | Archive

The Multimodal Interaction (MMI) Working Group today published Best practices for creating MMI Modality Components as a Group Note. Multimodal access means that people may use diverse "modalities" for interaction with the Web, including screen, keyboard, digital ink, voice, speech output, etc. The Working Group has defined a general and flexible framework providing interoperability among modality-specific components from different vendors - for example, speech recognition from one vendor and handwriting recognition from another. The current Note provides additional informative guidelines for authors of MMI modality components. Its purpose is to help authors create useful constituents that may be more easily incorporated into a multimodal system. Learn more about the Multimodal Interaction Activity.
