New version of the Roadmap of Web Applications on Mobile

W3C has published a new version of its Roadmap of Web Applications on Mobile, an overview of the various technologies developed in W3C that increase the capabilities of Web applications, and how they apply more specifically to the mobile context.

The April 2019 snapshot introduces a few additional technologies under incubation in the Web Platform Incubator Community Group and refreshes the status of other specifications. See the Change history for details. New exploratory work since the December 2018 snapshot:

• Cookie Store API, described in Data Storage
• KV Storage, described in Data Storage
• JS Self-Profiling API, described in Performance and Tuning
• Trusted Types, described in Security and Privacy

A few specifications have also progressed along the standardization track, starting with Web Authentication published as a W3C Recommendation (see Security and Privacy), including Resize Observer (see Device Adaptation) and Feature Policy which have now been adopted by Working Groups (see Security and Privacy), as well as DeviceOrientation Event Specification whose development has now resumed in the Devices and Sensors Working Group (see Sensors and Local Interactions).

Browser support for some of the specifications mentioned in the roadmap has improved since publication of the latest version of the roadmap in December 2018. For instance, Streams shipped in Firefox desktop (see Network and Communications) and Subresource Integrity has now shipped on all main browsers (see Security and Privacy).

Sponsored by Beihang University, this project is part of a set of roadmaps under development in a GitHub repository to document existing standards, highlight ongoing standardization efforts, point out topics under incubation, and discuss technical gaps that may need to be addressed in the future. New versions will be published on a quarterly basis, or as needed depending on progress of key technologies of the Web platform. We encourage the community to review them and raise comments, or suggest new ones, in the repository’s issue tracker.

W3C Strategic Highlights, Spring 2019

W3C released today its W3C Strategic Highlights – Spring 2019, a comprehensive survey of the essential work W3C conducts to achieve a Web for All, and select recent work in many areas where the Web can solve arising problems for real people.

To the pipeline of innovations to enable the Web to scale to meet the new challenges and opportunities, we are making recent additions:

• W3C chartered a Web Payment Security Interest Group to foster greater coordination and ultimately enhance the security and interoperability of Web payments.
• Web & Networks: what is needed for the Web to take advantage of 5G, QUIC, and Edge Computing changing the topology of network-based services? We have started to flesh out a group charter in the wake of the W3C Web5G workshop in May 2018.

• As the Web evolves continuously, some groups are looking for ways for specifications to do so as well. So-called “evergreen recommendations” or “living standards” aim to track continuous development (and maintenance) of features, on a feature-by-feature basis, while getting review and patent commitments.

  Continued progress in many areas demonstrates the vitality of the W3C and the Web community. We see the maturation and further development of an incredible number of new technologies coming to the Web.

New W3C Membership level aimed at organizations medium range revenues

Over the past several years the W3C Business Development team has heard from a number of mid-sized companies that while they are very interested in participating in W3C the Membership Fees were too high for them to justify. That was compounded by several conversations members of the W3C Team had with organizations in our newest vertical – Publishing. Many of the drivers in that vertical are in this category and had said a new level would be attractive for them. Based on this, we ran between Feb 2018 and Feb 2019 an experimental Membership level aimed at public organizations that have revenues in the medium range to see if the new level would, in fact, attract Members.

Our goal was to get eight new Members in that time and we’ve reached that goal! The organizations that have joined are Geotab (Automotive), Macmillan Learning (Publishing), Media Do Holdings (Publishing), New Relic, Inc. (Security), The Paciello Group (upgraded!), Ping Identity (Identity), SportTotal (Media) and W. W. Norton (Publishing). As you can see we have a diverse set of industries represented by these organizations and you’ll see them in various groups around W3C. Based on this success we have made this a permanent level and as organizations apply for Membership they will see this option.

This Membership Fee is available for existing Members as well if they qualify (it is designed for public organizations that have revenues between $50M and $500M USD, or equivalent in the other currencies of W3C Hosts). If you are interested in this, or have any questions or comments please contact J. Alan Bird, W3C Global Business Development Leader.

Call for Review: Web Authentication: An API for accessing Public Key Credentials Level 1 is a W3C Proposed Recommendation

The Web Authentication Working Group has published a Proposed Recommendation of Web Authentication: An API for accessing Public Key Credentials Level 1. This specification defines an API enabling the creation and use of strong, attested, scoped, public key-based credentials by web applications, for the purpose of strongly authenticating users. Conceptually, one or more public key credentials, each scoped to a given WebAuthn Relying Party, are created by and bound to authenticators as requested by the web application. The user agent mediates access to authenticators and their public key credentials in order to preserve user privacy. Authenticators are responsible for ensuring that no operation is performed without user consent. Authenticators provide cryptographic proof of their properties to Relying Parties via attestation. This specification also describes the functional model for WebAuthn conformant authenticators, including their signature and attestation functionality.

Comments are welcome through 14 February 2019.
