Evaluation and Report Language (EARL) Current Status

This page summarizes the relationships among specifications, whether they are finished standards or drafts. Below, each title links to the most recent version of a document.

Completed Work

W3C Recommendations have been reviewed by W3C Members, by software developers, and by other W3C groups and interested parties, and are endorsed by the Director as Web Standards. Learn more about the W3C Recommendation Track.

Group Notes are not standards and do not have the same level of W3C endorsement.

Evaluation and Report Language (EARL) 1.0 Schema

This document describes the formal schema of the Evaluation and Report Language (EARL) 1.0. The Evaluation and Report Language is a standardized vocabulary to express test results. The primary motivation for developing this language is to facilitate the exchange of test results between Web accessibility evaluation tools in a vendor neutral and platform independent format. It also provides reusable vocabulary for generic quality assurance and validation purposes. While this document focuses on the technical details of the specification, a companion document [Guide] describes the motivations for EARL and provides a tutorial introduction to its use.


Representing Content in RDF 1.0

This document is a specification for a vocabulary to represent Content in RDF. This vocabulary is intended to provide a flexible framework within different usage scenarios to semantically represent any type of content, be it on the Web or in local storage media. For example, it can be used by Web accessibility evaluation tools to record a representation of the assessed Web content in an Evaluation And Report Language (EARL) 1.0 Schema evaluation report. The document contains introductory information on its usage and some examples.


Developer Guide for Evaluation and Report Language (EARL) 1.0

This document is an introductory guide to the Evaluation and Report Language (EARL) 1.0. EARL is a vocabulary, the terms of which are defined across a set of specifications and technical notes, that is used to describe test results. The primary motivation for developing this vocabulary is to facilitate the exchange of test results between Web accessibility evaluation tools in a vendor-neutral and platform-independent format.


HTTP Vocabulary in RDF 1.0

The identification of resources on the Web by URI alone may not be sufficient, as other factors such as HTTP content negotiation might come into play. This issue is particularly significant for quality assurance testing, conformance claims, and reporting languages like the W3C Evaluation And Report Language (EARL). This document provides a representation of the HTTP vocabulary in RDF, to allow quality assurance tools to record the HTTP headers that have been exchanged between a client and a server. The RDF terms defined by this document represent the core HTTP specification defined by RFC 2616, as well as additional HTTP headers registered by IANA. These terms can also be used to record HTTPS exchanges.

Obsolete Specifications

These specifications have either been superseded by others, or have been abandoned. They remain available for archival purposes, but are not intended to be used.



Techniques For Accessibility Evaluation And Repair Tools

This document describes techniques that Web accessibility validation tools may use to evaluate the conformance of HTML documents to the Web Content Accessibility Guidelines 1.0 (WCAG 1.0). This document also describes techniques that Web authoring tools may use to help authors modify HTML documents to conform to WCAG 1.0. We anticipate that tool developers may develop accessibility validation and/or repair modules to be incorporated into commercial authoring tools, validation tools, and perhaps user agents.
