(image) W3C and the FIDO Alliance have achieved a major standards milestone in the global effort to bring simpler yet stronger web authentication to users around the world. The completion of the FIDO2 standardization efforts, the recent advancement of Web Authentication (WebAuthn) to Candidate Recommendation, –and the commitment of leading browser vendors to implement– enable users to login easily to online services with desktop or mobile devices with phishing-resistant security. WebAuthn, a standard web API to give users new methods to securely authenticate across sites and devices, has been developed in coordination with FIDO Alliance and is a core component of the FIDO2 Project along with FIDO’s Client to Authenticator Protocol (CTAP) specification, which enables an external authenticator, such as a security key or a mobile phone, to communicate strong authentication credentials locally over USB, Bluetooth or NFC to the user’s computer or tablet.

First Public Working Note of the Web of Things Protocol Binding Templates; updated WoT drafts

2018-04-06T08:33:07Z

The Web of Things provides layered interoperability between Things by using the WoT Interfaces and enables applications to interact with and orchestrate connected Things at Web scale.

The Web of Things provides layered interoperability between Things by using the WoT Interfaces and enables applications to interact with and orchestrate connected Things at Web scale. The Web of Things (WoT) Working Group has published today:

  • A First Public Working Group Note of the Web of Things (WoT) Protocol Binding Templates. This document describes the initial set of design pattern and vocabulary extensions to the WoT Thing Description. Protocol Binding Templates consist of reusable vocabulary and design pattern extensions to the WoT Thing Description format that enable an application client to interact, using a consistent interaction model, with Things that expose diverse protocols and protocol usage. See the specification to discover how to contribute to this draft.
  • An updated Working Draft of the Web of Things (WoT) Thing Description. This specification describes a formal model and common representation for a Web of Things Thing Description, which describes the metadata and interfaces of Things, where a Thing is an abstraction of a physical entity that provides interactions to and participates in the Web of Things. In addition to physical entities, Things can also represent virtual entities. A Thing Description instance can be hosted by the Thing itself or hosted externally due to Thing’s resource restrictions (e.g. limited memory space) or when a Web of Things-compatible legacy device is retrofitted with a Thing Description.
  • An updated Working Draft of the Web of Things (WoT) Scripting API. This specification describes a programming interface representing the WoT Interface that allows scripts run on a Thing to discover and consume (retrieve) other Things and to expose Things characterized by Properties, Actions and Events. Scripting is an optional “convenience” building block in WoT and it is typically used in gateways that are able to run a WoT Runtime and script management, providing a convenient way to extend WoT support to new types of endpoints and implement WoT applications like Thing Directory.

W3C Invites Implementations of Graphics-ARIA and Graphics-AAM

2018-03-29T12:49:35Z

The Accessible Rich Internet Applications Working Group invites implementations of two documents: WAI-ARIA Graphics Module (Graphics-ARIA): Assistive technologies need semantic information about the structures and expected behaviors of a document in order to convey appropriate information to persons with disabilities.

The Accessible Rich Internet Applications Working Group invites implementations of two documents:

  • WAI-ARIA Graphics Module (Graphics-ARIA): Assistive technologies need semantic information about the structures and expected behaviors of a document in order to convey appropriate information to persons with disabilities. This specification defines a WAI-ARIA 1.1 [WAI-ARIA-1.1] module of core roles specific to web graphics. These semantics allow an author to express the logical structure of the graphic to assistive technologies in order improve accessibility of graphics. Assistive technologies could then enable semantic navigation and adapt styling and interactive features, to provide an optimal experience for the audience. These features complement the graphics and document structure elements defined by HTML [HTML52] and SVG [SVG2].
  • Graphics Accessibility API Mappings (Graphics-AAM): The Graphics Accessibility API Mappings defines how user agents map the WAI-ARIA Graphics Module [GRAPHICS-ARIA-1.0] markup to platform accessibility APIs. It is intended for user agent developers responsible for accessibility in their user agent so that they can support the accessibility of graphics such as that created for [SVG] or [HTML52]. The implementation of this specification in user agents enables authors to produce more accessible graphics by conveying common graphics semantics to assistive technologies. It provides Accessibility API Mapping guidance for the roles defined in the WAI-ARIA Graphics Module [GRAPHICS-ARIA-1.0].

These documents are part of the WAI-ARIA suite described in the WAI-ARIA Overview.




W3C Invites Implementations of Encoding

2018-03-27T10:24:47Z

The Internationalization Working Group invites implementations of an updated Candidate Recommendation of Encoding.

The Internationalization Working Group invites implementations of an updated Candidate Recommendation of Encoding. The utf-8 encoding is the most appropriate encoding for interchange of Unicode, the universal coded character set. Therefore for new protocols and formats, as well as existing formats deployed in new contexts, this specification requires (and defines) the utf-8 encoding.

The other (legacy) encodings have been defined to some extent in the past. However, user agents have not always implemented them in the same way, have not always used the same labels, and often differ in dealing with undefined and former proprietary areas of encodings. This specification addresses those gaps so that new user agents do not have to reverse engineer encoding implementations and existing user agents can converge.

The Web Authentication Working Group invites implementations of the Web Authentication: An API for accessing Public Key Credentials Level 1 Candidate Recommendation. 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 Relying Party, are created and stored on an authenticator by the user agent in conjunction with the web application. The user agent mediates access to 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.

(image) The Permissions & Obligations Expression Working Group has just published a Recommendation for two documents, namely:

  • ODRL Information ModelThe Open Digital Rights Language (ODRL) is a policy expression language that provides a flexible and interoperable information model, vocabulary, and encoding mechanisms for representing statements about the usage of content and services. The ODRL Information Model describes the underlying concepts, entities, and relationships that form the foundational basis for the semantics of the ODRL policies.
    Policies are used to represent permitted and prohibited actions over a certain asset, as well as the obligations required to be met by stakeholders. In addition, policies may be limited by constraints (e.g., temporal or spatial constraints) and duties (e.g., payments) may be imposed on permissions.
  • ODRL Vocabulary & ExpressionThe ODRL Vocabulary and Expression describes the terms used in ODRL policies and how to encode them.
