The W3C Web Applications Working Group has published a W3C Recommendation of Indexed Database API. This document defines APIs for a database of records holding simple values and hierarchical objects. Each record consists of a key and some value. Moreover, the database maintains indexes over records it stores. An application developer directly uses an API to locate records either by their key or by using an index. A query language can be layered on this API. An indexed database can be implemented using a persistent B-tree data structure.
The Digital Publishing Interest Group has published a Group Note of DPUB IG Metadata Task Force Report. The Metadata Task Force of the DPUB IG found, through extensive interviews with representatives of various sectors and roles within the publishing ecosystem, that there are numerous pain points for publishers with regard to metadata but that these pain points are largely not due to deficiencies in the Open Web Platform. Instead, there is a widespread lack of understanding or implementation of the technologies that the OWP already makes available for addressing most of the issues raised. However, some of the very technologies that are little used or understood in most sectors of publishing are widely used and understood in certain other sectors (e.g., scientific publishing, libraries). Priorities that have emerged are the need for better understanding of the importance of expressing identifiers as URIs; the need for much more widespread use of RDF and its various serializations throughout the publishing ecosystem; and the need to develop a truly interoperable, cross-sector specification for the conveyance of rights metadata (while remaining agnostic as to the sector-specific vocabularies for the expression of rights). This Note documents in detail the issues that were raised; provides examples of available RDF educational resources at various levels, from the very technical to non-technical and introductory; and lists important identifiers used in the publishing ecosystem, documenting which of them are expressed as URIs, and in what sectors and contexts. It recommends that while little new technology is called for, the W3C is in a unique position to bridge today’s currently siloed metadata practices to help facilitate truly cross-sector exchange of interoperable metadata. This Note is thus intended to provide background and a context in which concrete work, whether by this Task Force or elsewhere within the W3C, may be undertaken.
The next gathering of the EDUPUB community will take place in Phoenix, Arizona (USA) on February 26 and 27, 2015. A preliminary program is now available, and registration is open. The summit will launch the implementation phase of EDUPUB, a cross-organizational initiative to develop a comprehensive open platform for next-generation learning content based on EPUB 3, IMS standards for learning environment integration, and the overall Open Web Platform.
The Web Annotation Working Group has published a First Public Working Draft of Web Annotation Data Model. 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 Data Model specification describes a structured model and format to enable annotations to be shared and reused across different hardware and software platforms.
The Digital Publishing Interest Group has published a Group Note of Digital Publishing Annotation Use Cases. This document describes the set of use cases generated for Annotation and Social Reading within the W3C Digital Publishing Interest Group, in coordination with the Open Annotation Community Group. This Note will also serve as an input for the W3C Web Annotation Working Group
The HTML Working Group published HTML5 as W3C Recommendation. This specification defines the fifth major revision of the Hypertext Markup Language (HTML), the format used to build Web pages and applications, and the cornerstone of the Open Web Platform.
“Today we think nothing of watching video and audio natively in the browser, and nothing of running a browser on a phone,” said Tim Berners-Lee, W3C Director. “We expect to be able to share photos, shop, read the news, and look up information anywhere, on any device. Though they remain invisible to most users, HTML5 and the Open Web Platform are driving these growing user expectations.”
HTML5 brings to the Web video and audio tracks without needing plugins; programmatic access to a resolution-dependent bitmap canvas, which is useful for rendering graphs, game graphics, or other visual images on the fly; native support for scalable vector graphics (SVG) and math (MathML); annotations important for East Asian typography (Ruby); features to enable accessibility of rich applications; and much more.
With today’s publication of the Recommendation, software implementers benefit from Royalty-Free licensing commitments from over sixty companies under W3C’s Patent Policy. Enabling implementers to use Web technology without payment of royalties is critical to making the Web a platform for innovation.

The Digital Publishing Interest Group has published a new Working Draft of “Requirements for Latin Text Layout and Pagination”. This document describes requirements for pagination and layout of books in latin languages, based on the tradition of print book design and composition. It is hoped that these principles can inform the pagination of digital content as well, and serve as a reference for the CSS Working Group and other interested parties.
Web Content Accessibility Guidelines Working Group today published updates of two Notes that accompany WCAG 2.0: Understanding WCAG 2.0 and Techniques for WCAG 2.0. (This is not an update to WCAG 2.0, which is a stable document.) For information on these updates, please see the Understanding WCAG and WCAG Techniques Updated September 2014 e-mail.
The HTML Working Group has published a Proposed Recommendation of HTML5. This specification defines the 5th major revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features are introduced to help Web application authors, new elements are introduced based on research into prevailing authoring practices, and special attention has been given to defining clear conformance criteria for user agents in an effort to improve interoperability. Comments are welcome through 14 October.
The call for papers for the “Books in Browsers: Advancing Open Web Standards and Digital Publishing” event has been published. The event will take place in San Francisco, on the 23-25 October, at the Gray Area Foundation for the Arts.
Books in Browsers is a small summit for the new generation of internet publishing companies, focusing on developers and designers who are building and launching tools for online storytelling, expression, and art. From the announcement above:
Over the last four years, Books in Browsers has advanced from a discussion of how startups might optimize existing publisher workflows to an exploration of the concept of “craft” in digital-native authoring and reading environments. This focus is bumping up squarely against the current limitations of web browsers to author, display, and link page elements together in ways that liberate the next generation of digital publishing.
Simultaneously, there is a burst of interest in how evolving web standards can advance publishing, and reciprocally how the frontiers of design, user interaction, and narrative can inform the objectives for web standards, common open source tools, and widely deployed services. One of the most obvious signposts of this engagement is the emergence of the W3C Digital Publishing Interest Group (DigPub IG).
