This document describes the formal schema of the Evaluation and Report Language (EARL) 1.0. The Evaluation and Report Language is a standardized format 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 Web quality assurance and validation purposes. While this document focuses on the technical details of the specification, a companion document describes the motivations for EARL and provides a tutorial introduction to its use. [Editor's note: link EARL 1.0 Guide once available.]
This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at http://www.w3.org/TR/.
The Evaluation and Repair Tools Working Group (ERT WG) encourages feedback about this document, Evaluation and Report Language (EARL) 1.0 Schema, by Web developers and researchers who have interest in software-supported evaluation and validation of Web sites. In particular, the group is looking for feedback about how robust and unambiguous the schema is, and how well it addresses content available on the Web. Specific questions are also highlighted within the relevant sections of this document.
The purpose of the Evaluation and Report Language (EARL) 1.0 Schema is to define a common vocabulary to express test results. It is intended as one part of a two-part replacement for the previous EARL 1.0 Working Draft of 6 December 2002. It meets the requirements specified in the Requirements for the Evaluation and Report Language (EARL) 1.0, and incorporates change requests received since the December 2002 Working Draft. While this document focuses on the technical details of the specification, a companion document describes the motivations for EARL and provides a tutorial introduction to its use. [Editor's note: link EARL 1.0 Guide once available.]
Please send comments to the mailing list of the ERT WG. The archives for this list are publicly available.
This is a W3C Working Draft of the Evaluation and Report Language (EARL) 1.0 Schema. This document will be published and maintained as a W3C Recommendation after review and refinement. Publication as a Working Draft does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
This document was produced under the 5 February 2004 W3C Patent Policy.

An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) with respect to this specification should disclose the information in accordance with section 6 of the W3C Patent Policy.
This document has been produced as part of the W3C Web Accessibility Initiative (WAI). The goals of the Evaluation and Repair Tools Working Group (ERT WG) are discussed in the Working Group charter. The ERT WG is part of the WAI Technical Activity.
[Editor's note: this section will be synchronized with the EARL 1.0 Guide as it is being developed.]
The Evaluation and Report Language (EARL) is a format to express test results. Test results include bug reports, test suite evaluations, and conformance claims. The test subject might be a Web site, an authoring tool, a user agent or some other entity. Thus, EARL is flexible. It enables any person, entity, or organization to state test results for any thing tested against any set of criteria.
Stating test results in EARL creates a variety of opportunities. The data can be:
A companion document to this specification is intended to provide more introductory material and explanation of the use cases for EARL.
EARL statements contain the following information:
Prose examples that demonstrate the above structure:
Example 1: a person carries out a manual evaluation of a Web page against a test criteria.
http://www.example.org/mypage
Example 2: an evaluation tool carries out automated evaluation of a Web page against a test criteria.

The namespace for EARL as specified in this draft is http://www.w3.org/WAI/ER/EARL/nmg-strawman#
.
[Editor's note: Versioning terms during the process of developing the vocabulary is an issue the group is working on. It is possible that a new namespace will be used for a final version of the vocabulary]
Where RDF terms are used in their abbreviated form (e.g. Assertion
or foaf:Person
), if no namespace is provided the term is in the EARL namespace. The following prefixes are used in examples throughout this document:
http://www.w3.org/WAI/ER/EARL/nmg-strawman#
which is described in this documenthttp://xmlns.com/foaf/0.1/
which is also where the terms are described [FOAF]http://purl.org/dc/elements/1.1/

described in [RDFS]http://www.w3.org/2002/07/owl#
described in [OWL]EARL is defined as an RDF vocabulary. The Resource Description Framework (RDF) [RDF] is a general-purpose language for describing information in a way that is machine-understandable.
EARL is an RDF vocabulary used to make statements about how a resource performed against a test. In common with other RDF it assumes that other vocabularies will be used as appropriate.
For more information on RDF, please refer to the following references:
The EARL 1.0 defines an RDF Vocabulary that consists of classes and properties. This section describes this core vocabulary as well as its usage while later sections describe extensibility of EARL 1.0; and conformance to EARL 1.0.
An Assertion is a statement about the results of performing a test. The earl:assertion
class relates the instances of an Assertor, Test Subject, Test Case, Test Mode, and Test Result for a specific assertion. It is a fundamental part of an EARL statement.
An Assertion MUST
have at least the following properties:
earl:assertedBy
earl:subject
earl:testcase
earl:mode
earl:result
Example 3: instance of an assertion expressed as an RDF/XML fragment.
<earl:Assertion rdf:ID="#assertion">
<earl:assertedBy rdf:resource="#assertor"/>
<earl:subject rdf:resource="#subject"/>
<earl:testcase rdf:resource="#testcase"/>
<earl:mode rdf:resource="http://www.w3.org/WAI/ER/EARL/nmg-strawman#manual"/>
<earl:result rdf:resource="http://www.w3.org/WAI/ER/EARL/nmg-strawman#pass"/>
</earl:Assertion>
An Assertor determines the results of a test (i.e. an assertor asserts and assertion). An earl:assertor
class must be either a Person, Software, or Compound Assertor.
An Assertor MUST
belong to one of the following types:
foaf:Person
foaf:Person
to describe a person. There SHOULDbe identifying information including a name, and a uniquely identifying property such as email address or an encrypted email address. The properties
foaf:name
, foaf:mbox
and foaf:mbox_sha1sum
are defined by FOAF [FOAF].earl:Software
earl:compoundAssertor
MUSThave at least one primary Assertor identified by the
earl:mainAssertor
property, and MAY, have secondary Assertor identified by the
earl:helpAssertor
property, as well as an OPTIONALdescription identified by the Dublin Core
dc:description
property.earl:Assertor
class, the instances can be a Person, Software, or recursively another Compound AssertorExample 4: an Assertor person called Bob B. Bobbington.
<foaf:Person rdf:ID="bob">
<foaf:name>Bob B. Bobbington</foaf:name>
<foaf:mbox rdf:resource="mailto:bob@example.org"/>
<foaf:mbox_sha1sum>1a9daad476f0158b81bc66b7b27b438b4b4c19c0</foaf:mbox_sha1sum>
</foaf:Person>
Example 5: an Assertor software called Cool Tool.
<earl:Software rdf:ID="tool">
<dc:title xml:lang="en">Cool Tool</dc:title>
<dc:description xml:lang="en">My favorite tool!</dc:description>
<dc:location>http://example.org/tools/#cool</dc:location>
<dct:hasVersion>1.0.3</dct:hasVersion>
</earl:Software>
Example 6: the Assertor from example 3 is the person from example 4 using the software from example 5.
<earl:compoundAssertor rdf:ID="assertor">
<earl:mainAssertor rdf:resource="#bob"/>
<earl:helpAssertor rdf:resource="#tool"/>
</earl:compoundAssertor>
The Test Subject is the class of things that have been tested. The earl:TestSubject
class MUST
have exactly one date specified by the Dublin Core dc:date
property. It MAY
also have any of the following properties:
dc:title
dc:description
dct:hasPart
dct:isPartOf
This class is intentionally generic to serve a wide variety of usages. For more specific use cases, the EARL earl:WebContent
or earl:Software
classes can be used in place to describe Web Content or Software that is being tested.
Example 7: Java applet that is part of a Web application
<earl:TestSubject rdf:ID="#applet">
<dc:title xml:lang="en">Login Applet</dc:title>
<dc:description xml:lang="en">Java applet that is used for system login</dc:description>
<dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#gDate">2005-06-25</dc:date>
<dct:isPartOf rdf:resource="http://example.org/"/>
</earl:TestSubject>
A Test Case is a test - usually one that can either be passed or failed. This may include many things such as validation requirements, code test cases, checkpoints from guidelines such as Web Content Accessibility Guidelines 1.0 [WCAG10], or others. These SHOULD
be identified with a URI.
A Test Case may be a single test, or may be a part of a larger compound test suite. These relations MAY
be described using Dublin Core's dct:hasPart
or dct:isPartOf
properties. Additionally, the Web location or a description for the test MAY
be included by using the Dublin Core dc:location
or dc:description
properties.
[Editor's note: This class is included for convenience, since it allows various useful properties to be described in simple standard RDF. The working group will deprecate this class if they find an appropriate replacement from a language designed for describing test cases, something which is beyond the scope of the current specification.]
Example 8: instance of a test case that is additionally described with a title and its relationship to a test suite.
<earl:TestCase rdf:ID="html">
<dc:title xml:lang="en">HTML Test Suite</dc:title>
<dc:description xml:lang="en">Tests specifically for the Hyper Text Markup Language</dc:title>
<dct:isPartOf rdf:resource="http://example.org/tests/#all"/>
<dct:hasPart rdf:resource="http://example.org/tests/#282"/>
<dc:location>http://example.org/tests/html/</dc:location>
</earl:TestCase>
Example 9: test cases that don't need to be described further can be shortened as follows:
<earl:testcase rdf:resource="http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-text-equivalent"/>
The Test Mode MUST
be exactly one of the following pre-defined values, or subclasses of them (see section Extensibility for more explanation):
earl:manual
earl:compoundAssertor
class of the Assertor.earl:automatic
earl:heuristic
Example 10: instance of an assertion that has been carried out in manual mode
<earl:Assertion rdf:about="http://example.org/#assertion">
<earl:mode rdf:resource="http://www.w3.org/WAI/ER/EARL/nmg-strawman#manual"/>
</earl:Assertion>
The actual result of the test. This MUST
have exactly one earl:validity
properties to describe a Validity Level. It MAY
also include a Confidence Level, using the EARL earl:confidence
properties; or a description, using the Dublin Core dc:description
property. The description is meant to be human-readable text or markup (for example HTML included as an XML Literal), and SHOULD
include an identification for the natural language.
[Editor's note: the confidence property is still under discussion, please refer to the Confidence Level for more information]
The following example shows a result with a validity of fail and a description of the problem in English, and encoded in XHTML format:
Example 11: A test result with a validity and a description property
<earl:result rdf:parseType="Resource">
<earl:validity rdf:resource="http://www.w3.org/WAI/ER/EARL/nmg-strawman#fail"/>
<dc:description rdf:parseType="Literal">
<div xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
<p>The <code>table</code> element is not allowed to appear
inside a <code>p</code> element</p>
</div>
</dc:description>
</earl:result>
Outcome of a test. The Validity Level MUST
be one of the following pre-defined values, or subclasses of them (see section Extensibility for more explanation):
earl:pass
earl:fail
earl:cannotTell
earl:notApplicable
earl:notTested
[Editor's note: there are currently three values specified as confidence values, of high, medium, and low. These are under discussion and may be removed or significantly revised since it is not yet clear how to ensure that they can be made unambigous and used interoperably]
Confidence in the result by an Assertor. This MAY
be used where a tool wants to assert that it has different levels of confidence about two possible results (for example low confidence that a test has been passed, but also high confidence that it is not applicable). The values of the confidence level MUST
be one of the following pre-defined values, or subclasses of them (see section Extensibility for more explanation):
earl:high
earl:medium
earl:low
A piece of software such as an authoring tool, browser, or evaluation tool. Software MUST
have a title (using the Dublin Core property dc:title
) and MAY
have descriptions, version information, and Web location (using the Dublin Core terms dc:description
, dct:hasVersion
, and dc:location
). Additionally, if it is used as a Test Subject then it inherits additional properties such as dc:date
(REQUIRED
) as well as dct:isPartOf
and dct:hasPart
(OPTIONAL
).
[Editor's note: earl:Tool
used to be a sub class of Assertor in previous versions of this Working Draft but it has been deprecated in favour of earl:Software
, which may also be reused a Test Subject.]
Example 12: The software which was an Assertor in example 5 is now a Test Subject.
<earl:Software rdf:about="#tool">
<dc:title xml:lang="en">Cool Tool</dc:title>
<dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#gDate">2005-06-25</dc:date>
</earl:Software>
Information on the World Wide Web. This should include enough information to identify the content actually tested, taking account of content type and language negotiation and similar factors that can change the content actually served. This class is intended to be used as a test subject but can be reused for other purposes (outside EARL) as well. The Web content class has the following properties:
dc:format
dc:location
earl:httpRequest
earl:httpResponse
A Web Content class MAY
include several request/response sequences to document the content and language negotiation that took place before the content was finally sent.
[Editor's note: the request/response properties of this class are still being refined]
Because EARL is written as an RDF vocabulary, it is extensible; that is, it is simple to add new terms or otherwise modify (for example by subclassing) them to fit your own specific application demands more closely. EARL was designed to be generic for usages in quality assurance but may need to be extended to fit particular domains. You may think of EARL as a core set of structures and terms. In addition, the working group expects to work on at least a couple of areas and extend the specification (especially with respect to Web accessibility evaluation) before publishing it as a Recommendation.
[Editor's note: there will be examples of extending EARL provided in a later draft]
The EARL vocabulary uses OWL [OWL] to provide formal constraints on what is valid EARL.
[Editor's note: the topic of conformance requirements beyond those implicit in the vocabulary definition will be discussed, and results will be incorporated into a future draft.]
[Editor's note: need to make a schema available at the namespace URI, which includes OWL information on deprecated terms]

This section records current changes and future plans for changes as the working draft matures to Recommendation level.
New terms have been introduced to the vocabulary, sometimes as replacements for deprecated terms that existed in EARLier drafts, sometime to introduce new funtionality
Software
Tool
. It can be used to decribe a assertor tools or test subjects.singleAssertor
, compoundAssertor
mainAssertor
, helpAssertor
httpRequest
, httpResponse
WebContent
(or a "Delivery Unit" on the Web).A number of terms have been deprecated, either in favour of terms from existing widely-used vocabularies, or because their use is somehow problematic. While this deprecation is provisional, no RDF has been published formally noting them as deprecated (for example through OWL). A quick guide to terms that have been provisionally deprecated:
reprOf
UserAgent
, Tool
Software
class.platform
message
, format
dc:description
and dc:format
.Person
, name
, email
, contactInfo
The working group is considering several open issues which would lead to extending the current vocabulary before it reaches recommendation.
As well as issues noted in the draft, the following issues are under active consideration:
A mechanism to provide further evidence used to make a claim. This could be a copy of the web content analysed for a particular test, or a rule describing how may tests are required to pass some compound test, and pointers to the individual results that together satisfy the rule.
Within Web content, for the use case of testing accessibility, it is very valuable to point to the location(s) that cause the test to pass or fail. This is also true of software interfaces and various other kinds of subject. The working group has agreed in principle to include a mechanism for recording this information in an EARL report, but has not yet developed or found the necessary terms.
There are currently placeholder properties httpRequest
and httpResponse
for HTTP transaction information. The group expects to develop these further, either themselves or with an existing vocabulary.
This is under review by the working group. It is not clear how the currently defined model can be used interoperably, and whether there is an alternative approach that would allow for a more interoperable statement of confidence in some results.
