This specifies a browser API for the measurement of advertising performance. The goal is to produce aggregate statistics about how advertising leads to conversions, without creating a risk to the privacy of individual web users. This API collates information about people from multiple web origins, which could be a significant risk to their privacy. To manage this risk, the information that is gathered is aggregated using an aggregation service that is trusted by the user-agent to perform aggregation within strict limits. Noise is added to the aggregates produced by this service to provide differential privacy. Websites may select an aggregation service from the list of approved aggregation services provided by the user-agent.</p> </div> 0 UI Events KeyboardEvent key Values and code Values are W3C Recommendations The Web Applications Working Group published UI Events KeyboardEvent key Values and UI Events KeyboardEvent code Values as W3C Recommendations.

SHACL is 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". As SHACL shape graphs are used to validate that data graphs satisfy a set of conditions they can also be viewed as a description of the data graphs that do satisfy these conditions. Such descriptions may be used for a variety of purposes beside validation, including user interface building, code generation and data integration.</li><li><a href="https://www.w3.org/TR/2025/WD-shacl12-sparql-20250318/">SHACL 1.2 SPARQL Extensions</a>: This document defines SPARQL-related extensions of the SHACL Shapes Constraint Language. While the Core part of SHACL defines the basic syntax of shapes and the most common constraint components supported by SHACL, the SPARQL-related extensions cover features that extend the expressiveness of Core by means of SPARQL. In particular, this document defines how constraints and constraint components can be defined using SPARQL.</li></ul> </div> 0 DPub-ARIA 1.1 and DPub-AAM 1.1 are W3C Proposed Recommendations Today the Accessible Rich Internet Applications Working Group published Digital Publishing WAI-ARIA Module 1.1 and Digital Publishing Accessibility API Mappings 1.1 as W3C Proposed Recommendations.
