<h2>Documenting conformance to standards</h2>
<p> This subsection shows different modelling patterns combining DQV [[vocab-dqv]] with PROV [[PROV-O]] and EARL [[EARL10-Schema]] to represent the conformance degree to a stated quality standard and the details about the conformance tests.

<p> Further information about the tests can be provided using EARL [[EARL10-Schema]]. EARL provides specific classes to describe the testing activity, which can be adopted in conjuction to PROV.
The following example describes the Testing activity a:TestingActivity as an EARL Assertion instead of a qualified association on the PROV activity. The EARL Assertion states the dataset a:Dataset has been tested with the conformance test a:ConformanceTest, and it has passed the test as described in a:testResult.

Depending on the details required about test, DQV can express the testing activity and errors as well. In the following, :error is a quality annotation that represents the previous error, and a:testResult is defined as a DQV quality metadata to collect the above annotations and the compliance measurements providing provenance information.

Of course, the above modelling patterns can be exploited for representing any quality checks not only conformance to standards.
