The Web of Things (WoT) Working Group has published the following three First Public Working Drafts:

Web of Things (WoT) Architecture: This document describes the abstract architecture for the W3C Web of Things, which consists of three initial building blocks, i.e., (1) WoT Thing Description, (2) WoT Scripting API and (3) WoT Binding Templates.

Web of Things (WoT) Thing Description: This document describes a formal model and common representation for a Web of Things Thing Description. A Thing Description 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.

Web of Things (WoT) Scripting API: This document 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.

The group is planning to publish the third building block, WoT Binding Templates, as a First Public Working Draft shortly.

(image) The Spatial Data on the Web Working Group has published a Proposed Recommendation of the Semantic Sensor Network Ontology specification. The specification defines an ontology for describing sensors and their observations, the involved procedures, the studied features of interest, the samples used to do so, and the observed properties, as well as actuators.

SSN follows a horizontal and vertical modularization architecture by including a lightweight but self-contained core ontology called SOSA (Sensor, Observation, Sample, and Actuator) for its elementary classes and properties. With their different scope and different degrees of axiomatization, SSN and SOSA are able to support a wide range of applications and use cases, including satellite imagery, large-scale scientific monitoring, industrial and household infrastructures, social sensing, citizen science, observation-driven ontology engineering, and the Web of Things. Comments are welcome through 5 October 2017.

The CSS Working Group invites implementations of Media Queries Level 4 Candidate Recommendation. Media Queries allow authors to test and query values or features of the user agent or display device, independent of the document being rendered. They are used in the CSS @media rule to conditionally apply styles to a document, and in various other contexts and languages, such as HTML and Javascript.

Media Queries Level 4 describes the mechanism and syntax of media queries, media types, and media features. It extends and supersedes the features defined in Media Queries Level 3.

CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.

Proposal to Republish Previous Versions of HTML and XHTML as Obsolete Recommendations

2017-09-14T12:18:44Z

W3C Advisory Committee Representatives received today a proposal to republish a series of HTML and XHTML W3C Recommendations as Obsolete Recommendations, in response to a request from the Web Platform Working Group as these specifications are superseded by new versions and are no longer recommended for implementation on the Web platform. This has been made […]

(image) W3C Advisory Committee Representatives received today a proposal to republish a series of HTML and XHTML W3C Recommendations as Obsolete Recommendations, in response to a request from the Web Platform Working Group as these specifications are superseded by new versions and are no longer recommended for implementation on the Web platform.

This has been made possible by the addition this year to the W3C Process Document of a process to mark a Recommendation as Obsolete. An obsolete specification is one that the W3C community has decided should no longer be used. For example, it may no longer represent best practices, or it may not have received wide adoption and is not apparently likely to be adopted in the future. The status of an obsolete specification remains active under the W3C Patent Policy, but it is not recommended for future implementation. In this case, “obsolete” states that each of these specifications has been superseded by more recent specifications.

For example, as part of our commitment to the platform’s future, we recommend that all implementers use the latest HTML5 –where HTML5 is the term to refer to the family of specifications. We are proposing to obsolete the particular 28 October 2014 W3C Recommendation which henceforth shall be called HTML 5.0, which has been superseded by HTML 5.1, a W3C Recommendation since 1 November 2016. This aims at clarifying the status of the document and point developers and implementers to the latest version of HTML5.

The Web Platform Working Group invites implementations of Indexed Database API 2.0 Candidate Recommendation. This specification is the Second Edition of Indexed Database API. The First Edition became a W3C Recommendation on 8 January 2015.

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 RDF Data Shapes Working Group has published Shapes Constraint Language (SHACL) as a W3C Recommendation. This document defines the SHACL Shapes Constraint Language, a language for validating RDF graphs against a set of conditions. These conditions are provided as shapes and other constructs expressed in the form of an RDF graph. RDF graphs that are used in this manner are called “shapes graphs” in SHACL and the RDF graphs that are validated against a shapes graph are called “data graphs”. Such descriptions may be used for a variety of purposes beside validation, including user interface building, code generation and data integration. Ongoing discussion, including product announcements and planning for future versions, is welcome in the SHACL Community Group.
