First Public Working Draft: Web Payments Use Cases 1.0
16 April 2015
<http://www.w3.org/blog/news/archives/4616>
Today the Web Payments Interest Group published a first draft
of "Web Payments Use Cases." The current payment landscape is
changing rapidly, offering new opportunities for greater
security, improved usability on mobile, and payment innovations
in areas like digital wallets and cryptocurrencies. The lack of
open standards for integrating the latest developments into the
Web makes it more difficult for merchants, Web developers, and
payment service providers to adapt to new payment solutions.
Fragmented regulatory environments further complicate the
payments landscape.
<http://www.w3.org/Payments/IG>
<http://www.w3.org/TR/2015/WD-web-payments-use-cases-20150416/>
To achieve greater interoperability among merchants and their
customers, payment providers, software vendors, mobile
operators, and payment networks, the W3C Web Payments Interest
Group, launched in October 2014, is developing a roadmap for
standards to improve the interoperability of payments on the
Web. Today’s use cases document establishes the group’s initial
scope of work. Guided by these use cases, the W3C Web Payments
Interest Group (see the current participants) plans to derive
architecture and associated technology requirements. That work
will form the basis of conversations with W3C groups and the
broader payments industry about what standards (from W3C or
other organizations) will be necessary to fulfill the use cases
and achieve the full potential of Web payments.

Updated Candidate Recommendation for CSS Cascading and Inheritance
Level 3
16 April 2015
<http://www.w3.org/blog/news/archives/4620>
The Cascading Style Sheets (CSS) Working Group has published an
updated Candidate Recommendation of "CSS Cascading and
Inheritance Level 3." This CSS module describes how to collate
style rules and assign values to all properties on all
elements. By way of cascading and inheritance, values are
propagated for all properties on all elements. CSS is a
language for describing the rendering of structured documents
(such as HTML and XML) on screen, on paper, in speech, etc.

Four Drafts Published by the CSV on the Web Working Group
16 April 2015
<http://www.w3.org/blog/news/archives/4619>
The CSV on the Web Working Group has published a new set of
Working Drafts, which the group considers feature complete and
implementable.
<http://www.w3.org/2013/csvw/wiki/Main_Page>
* Model for Tabular Data and Metadata on the Web: an abstract
model for tabular data, and how to locate metadata that
enables users to better understand what the data holds;
this specification also contains non-normative guidance on
how to parse CSV files
* Metadata Vocabulary for Tabular Data: a JSON-based format
for expressing metadata about tabular data to inform
validation, conversion, display and data entry for tabular
data
* Generating JSON from Tabular Data on the Web: how to
convert tabular data into JSON
* Generating RDF from Tabular Data on the Web: how to convert
tabular data into RDF
The group is keen to receive comments on these specifications,
either as issues on the Group’s GitHub repository or by posting
to public-csv-wg-comments@w3.org.
<https://github.com/w3c/csvw/issues>
<mailto:public-csv-wg-comments@w3.org>
The CSV on the Web Working Group would also like to invite
people to start implementing these specifications and to donate
their test cases into the group’s test suite. Building this
test suite, as well as responding to comments, will be the
group’s focus over the next couple of months.

First Public Working Draft: ARIA in HTML
14 April 2015
<http://www.w3.org/blog/news/archives/4605>
The HTML Working Group has published a Working Draft of "ARIA
in HTML." This specification defines the web developer rules
(author conformance requirements) for the use of wai-aria-1.1
attributes on HTML51 elements. It also defines requirements for
Conformance Checking tools. Learn more about the HTML Activity.

Requirements for Hangul Text Layout and Typography Draft Published
14 April 2015
<http://www.w3.org/blog/news/archives/4603>
The Internationalization Working Group has published a Working
Draft of "Requirements for Hangul Text Layout and Typography."
This document describes requirements for general Korean
language/Hangul text layout and typography realized with
technologies like CSS, SVG and XSL-FO. The document is mainly
based on a project to develop the international standard for
Korean text layout. Learn more about the Internationalization
Activity.

The Web Applications Working Group has published a Working
Draft of "Gamepad." The Gamepad specification defines a
low-level interface that represents gamepad devices. Learn more

First Public Working Draft: SHACL Use Cases and Requirements
14 April 2015
<http://www.w3.org/blog/news/archives/4597>
The RDF Data Shapes Working Group has published a Working Draft
of "SHACL Use Cases and Requirements." To foster the
development of Shapes Constraint Language (SHACL), this
document includes a set of use cases and requirements that
motivate a simple language and semantics for formulating
structural constraints on RDF graphs. All use cases provide
realistic examples describing how people may use structural
constraints to validate RDF instance data. Note, this document
avoids the use of any specific vocabulary that might be
introduced by the SHACL specification. Learn more about the
Data Activity.

WOFF File Format 2.0; WOFF 2.0 Evaluation Report Drafts Published
14 April 2015
<http://www.w3.org/blog/news/archives/4594>
The WebFonts Working Group has published a Working Draft of
"WOFF File Format 2.0." Based on experience with WOFF 1.0,
which is widely deployed, this specification was developed to
provide improved compression and thus lower use of network
bandwidth, while still allowing fast decompression even on
mobile devices. This is achieved by combining a content-aware
pre-processing step and improved entropy coding, compared to
the Flate compression used in WOFF 1.0.
<http://www.w3.org/Fonts/WG/>
<http://www.w3.org/TR/2015/WD-WOFF2-20150414/>
The Group also published a Working Draft of "WOFF 2.0
Evaluation Report." Web Open Font Format (WOFF) 2.0 is a
proposed update to the existing WOFF 1.0 with improved
compression. This report lists requirements for successful
deployment, evaluates how the requirement may be met, and
examines the compression gains and tradeoffs vs. code
complexity, encode and decode time. This document is
non-normative. Learn more about the Fonts Activity.

14 April 2015
<http://www.w3.org/blog/news/archives/4600>
The Web Real-Time Communications Working Group and Device APIs
Working Group have published a Last Call Working Draft of
"Media Capture and Streams." This document defines a set of
JavaScript APIs that allow local media, including audio and
video, to be requested from a platform. Comments are welcome
through 15 May 2015. Learn more about the Ubiquitous Web
Applications Activity.
