The Web Application Security Working Group has published a Proposed Recommendation of Subresource Integrity. This specification defines a mechanism by which user agents may verify that a fetched resource has been delivered without unexpected manipulation. Comments are welcome through 07 June.
The Web Components Patent Advisory Group (PAG), launch in January 2016, has published a report recommending per Option 1 of the W3C Patent Policy, that W3C continue work on the Web Components Specification. The PAG concludes that the initial concern has been resolved, enabling the Working Group to continue. More detail is available in the PAG report. W3C launches a PAG to resolve issues in the event a patent has been disclosed that may be essential, but is not available under the W3C Royalty-Free licensing terms.
W3C announced today Blockchains and the Web Workshop, 29–30 June 2016, in Cambridge, MA, USA, hosted by the MIT Media Lab.
Many projects and companies are looking at ways to use the Bitcoin
blockchain or other public or private distributed ledgers, to record an
immutable timestamped public record that can be independently verified by
any stakeholder. What does this mean for Web technologies, beyond payments? What emerging
capabilities could blockchains enable for the Web, such as distributed
identity management? Conversely, should features be added to the Web
Platform and to browsers to enable blockchain use cases, such as a
developers to take advantage of blockchains?
We invite participation from diverse players in the blockchain community:
Representatives from communities such as Bitcoin, Hyperledger, and
Ethereum; browser developers interested in adding support for blockchain
APIs, identity systems, and other functionality; digital currency
projects; financial institutions; developers of blockchain systems who
want to improve interoperability; privacy/security researchers; and more.
W3C membership is not required to participate. The event is open to all. All participants are required to submit a position paper by 27 May 2016.
The Internationalization Working Group has published a Group Note of Unicode in XML and other Markup Languages. The Unicode Standard defines the universal character set. Its primary goal is to provide an unambiguous encoding of the content of plain text, ultimately covering all languages in the world, but also major text-based notational systems for science, technology, music, and scholarship. This document contains guidelines on the use of the Unicode Standard in conjunction with markup languages such as XML.
The Digital Publishing Interest Group has published a Group Note of Digital Publishing and Accessibility in W3C Documents. This document describes how W3C guidelines (including but not limited to WCAG20, ATAG20, UAAG20, and WAI-ARIA) and their principles, guidelines, and success criteria can be applied to the needs of Digital Publishing. It provides informative guidance, but does not set requirements.
The Tracking Protection Working Group invites implementation of the Candidate Recommendation of Tracking Compliance and Scope. Do Not Track is designed to provide users with a simple mechanism to express a preference to allow or limit online tracking. Complying with the user’s preference includes limits on the collection, retention and use of data collected as a third party to user actions and the sharing of data not permanently de-identified. This specification defines a set of practices for compliance with a user’s Do Not Track (DNT) tracking preference to which a server may claim adherence.
The Web Payments Working Group has published First Public Working Drafts of the following specifications. These are the first of a suite of specifications to make payments on the Web easier and more secure.
- Payment Request API, which describes a web API to allow merchants (i.e., web sites selling physical or digital goods) to easily accept payments through different payment methods with minimal integration.
- Basic Card Payment describes the data formats used by the Payment
Request API to support payment by payment cards such as credit or
- Payment Method Identifiers defines payment method identifier strings so that components in the payment ecosystem can determine which parties support which payment methods.
The Working Group published a FAQ and welcomes feedback on these early drafts.
The Timed Text Working Group has published a W3C Recommendation of TTML Profiles for Internet Media Subtitles and Captions 1.0 (IMSC1). This document specifies two profiles of TTML1: a text-only profile and an image-only profile. These profiles are intended to be used across subtitle and caption delivery applications worldwide, thereby simplifying interoperability, consistent rendering and conversion to other subtitling and captioning formats.
