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

2017-08-11T16:09:45Z

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as Obsolete Recommendations, in response to a request from the Web Platform Working Group as these specifications are superseded by new versions and are no longer recommended for implementation on the Web platform.

(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as Obsolete Recommendations, in response to a request from the Web Platform Working Group as these specifications are superseded by new versions and are no longer recommended for implementation on the Web platform.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 For example, it may no longer represent best practices, or it may not have received wide adoption and is not apparently likely to be adopted in the future.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 In this case, “obsolete” states that each of these specifications has been superseded by more recent specifications.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to obsolete the particular 28 October 2014 W3C Recommendation which henceforth shall be called HTML 5.0, which has been superseded by HTML 5.1, a W3C Recommendation since 1 November 2016.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.

(image) The Spatial Data on the Web Working Group invites implementations of Semantic Sensor Network Ontology Candidate Recommendation. 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.

The CSS Working Group has published a First Public Working Draft of CSS Overflow Module Level 4. This module contains the features of CSS relating to new mechanisms of overflow handling in visual media (e.g., screen or paper). In interactive media, it describes features that allow the overflow from a fixed size container to be handled by pagination (displaying one page at a time). It also describes features, applying to all visual media, that allow the contents of an element to be spread across multiple fragments, allowing the contents to flow across multiple regions or to have different styles for different fragments.

The XSLT Working Group has published XSL Transformations (XSLT) Version 3.0 as a Recommendation. XSLT 3.0 enables transformations to be performed in streaming mode, where neither the source document nor the result document is ever held in memory in its entirety.

Another important enhancement is provided by XSL packages, to improve the modularity of large stylesheets, allowing stylesheets to be developed from independently-developed components with a high level of software engineering robustness.

XSLT 3.0 is designed to be used in conjunction with XPath 3.0, which offers higher-order functions. It also specifies the map functionality exactly as it is in the XPath 3.1 Recommendation, and implementors may also offer support for other XPath 3.1 additions compared to XPath 3.0, like arrays.

Digital Publishing Accessibility API Mappings (DPub-AAM) has been published as a Candidate Recommendation by Accessible Rich Internet Applications (ARIA) Working Group and is now undergoing implementation finalization and testing. DPub-AAM describes how roles in the Digital Publishing WAI-ARIA Module 1.0 should be exposed to accessibility APIs. Implementation of this specification makes it possible for assistive technologies to provide enhanced navigation among landmarks unique to digitally-published documents, and to identify document-specific features which should be presented to the user, such as crossing a page boundary. These mappings will also be used in part for verifying implementation success of Digital Publishing WAI-ARIA Module 1.0 which is already a Candidate Recommendation. The draft implementation report shows the progress of testing. Please send implementation information or comments by 7 July 2017. Read about the Web Accessibility Initiative (WAI).

The Accessible Rich Internet Applications (ARIA) Working Group has published a First Public Working Draft of Personalization Semantics 1.0. Personalization involves tailoring aspects of the user experience to meet the needs and prefences of the user. The introduction of standardized semantics allows web applications to customize the exposure of that content to one that is familiar to individuals based on their needs and preferences. This specification was initially developed in a task force to provide technology features needed to meet needs of users with cognitive or learning disabilities, but is intended to support a wide variety of personalization use cases. Please comment by filing GitHub issues in the personalization semantics repository or, if this is not feasible, by email to public-aria@w3.org, by 30 June 2017.
