Sir Tim Berners-Lee named recipient of the ACM A.M. Turing Award

ACM turing award logopicture of Tim Berners-LeeToday, Tuesday 4 April, the ACM, the Association for Computing Machinery, named Sir Tim Berners-Lee, inventor of the Web and Director of the World Wide Web Consortium, as the recipient of the 2016 ACM A.M. Turing Award.

The Turing award is recognized as the highest distinction in Computer Science and is sometimes referred to as the “Nobel Prize of Computing.” Sir Tim is being given this award for inventing the World Wide Web, the first web browser, and the fundamental protocols and algorithms allowing the Web to scale. The Web is considered one of the most influential computing innovations in history.

Sir Tim’s development and guardianship of the building blocks of the Web, the standards upon which it is built upon, continues at W3C. Jeff Jaffe, CEO of W3C, stated: “The Web has had an immense impact on the world; transforming every part of society: how we communicate, how we learn, how we acquire information, and how we engage in commerce. Tim’s soaring vision of what was possible in the world is anchored on breakthrough contributions to computing – which is what is recognized by the Turing Award.”

For more information on the award, Sir Tim, and the W3C, see the W3C press release.

Spatial Data on the Web Best Practices Note Published

The Spatial Data on the Web Working Group has published a Group Note of Spatial Data on the Web Best Practices. This document advises on best practices related to the publication and usage of spatial data on the Web; the use of Web technologies as they may be applied to location. The best practices are intended for practitioners, including Web developers and geospatial experts, and are compiled based on evidence of real-world application. These best practices suggest a significant change of emphasis from traditional Spatial Data Infrastructures by adopting a Linked Data approach. As location is often the common factor across multiple datasets, spatial data is an especially useful addition to the Linked Data cloud; the 5 Stars of Linked Data paradigm is promoted where relevant.

W3C Invites Implementations of WebDriver

The Browser Testing and Tools Working Group invites implementation of the Candidate Recommendation of WebDriver. WebDriver is a remote control interface that enables introspection and control of user agents. It provides a platform and language-neutral wire protocol as a way for out-of-process programs to remotely instruct the behavior of web browsers as well as a set of interfaces to discover and manipulate DOM elements in web documents and to control the behavior of a user agent. It is primarily intended to allow web authors to write tests that automate a user agent from a separate controlling process, but may also be used in such a way as to allow in-browser scripts to control a possibly separate browser.

W3C Invites Implementations of Resource Timing Level 1

The Web Performance Working Group invites implementation of the Candidate Recommendation of Resource Timing Level 1. This specification defines an interface for web applications to access the complete timing information for resources in a document. User latency is an important quality benchmark for Web Applications. While JavaScript-based mechanisms can provide comprehensive instrumentation for user latency measurements within an application, in many cases, they are unable to provide a complete end-to-end latency picture. This document introduces the PerformanceResourceTiming interface to allow JavaScript mechanisms to collect complete timing information related to resources on a document. Navigation Timing 2 extends this specification to provide additional timing information associated with a navigation.

XQuery 3.1, XQueryX 3.1, XPath 3.1 and supporting documents now a W3C Recommendation

Screenshot of W3C Standards showing XQuery and XPath 3.1 documents The XML Query Working Group and the XSLT Working Group have published six documents as W3C Recommendations to strengthen JSON and Web Platform support through maps, arrays, new functions:

The 3.1 work extends XPath and XQuery with map and array data structures along with additional functions and operators for manipulating them; a primary motivation was to enhance JSON support.

XPath is a domain-specific language for identifying and extracting nodes from a tree (typically) built from XML or JSON and defined by the XQuery and XPath Data Model) and also an expression language with typed tree nodes and functions among the first-class objects. XPath expressions can call functions and use operators defined in the Functions and Operators specification.

XQuery extends XPath to support complex joins, windowing, grouping and other operations across collections of trees that are potentially stored in high-performance indexed databases.

XQueryX is an XML representation of XQuery expressions.

The Serialization specification describes how results of XPath and XQuery(X) expressions can be delivered in HTML, XHTML, JSON, XML or text.

Call for Review: Encrypted Media Extensions Proposed Recommendation Published

The HTML Media Extensions Working Group has published a Proposed Recommendation of Encrypted Media Extensions. The specification extends HTMLMediaElement to define a common API to control playback of protected content. EME does not define a content protection or Digital Rights Management system. The common API may be used to discover, select and interact with such systems as well as with simpler content encryption systems. Comments are welcome through 13 April. Please, read more in the public announcement.

Ivan Herman and Bill McCoy to address the Publishing and EPUB road-map at EPUB Summit

EPUB logoPublishing@W3C champion Bill McCoy and W3C Fellow from CWI Dr. Ivan Herman will join an impressive line-up of speakers next week at the EPUB Summit, 9-10 March 2017 in Brussels, Belgium, hosted by W3C member EDRLab. The second such event, EPUB Summit will focus on the future direction of EPUB 3, now under W3C oversight following the combination with IDPF. Registration for the EPUB Summit is still open.

A technical expert in the field, Herman is part of the leadership team of Publishing@W3C as well as the overall Strategy team of W3C. Herman was recently appointed a W3C Fellow by CWI, Amsterdam, where he is a member of the Distributed and Interactive Systems research group. He played a seminal role in the combination of W3C and IDPF and has served as primary technical staff driver for the Digital Publishing at the W3C since inception in 2013. At the EPUB Summit Herman will talk about the IDPF/W3C combination, and the roadmap for upcoming technical work for the development of new standards in Publishing.

McCoy, former Executive Director for IDPF, will lead the closing session at the EPUB Summit, integrating the collective sessions and ideas into the roadmap for Publishing@W3C.
