+<p>This document defines the RML-LV test cases, consisting of a collection of test case documents (input and expected output).
+The purpose of the test cases is to determine the conformance of tools that execute RML rules to the RML-LV specification.</p>

+<p>The test cases are semantically described for re-usability and shareability following the <a href="https://www.w3.org/2006/03/test-description">W3C Test case description</a>.
+Each <code>test:Testcase</code> as the following properties:</p>
+<ul>
+<li><code>dcterms:identifier</code>: unique ID of the test case.</li>
+<li><code>rmltest:hasError</code>: if an error of the RML Processor is expected or not.</li>
+<li><code>rmltest:input</code>: One or more input data of the test case.</li>
+<li><code>rmltest:output</code>: One or more output data of the test case.</li>
+<li><code>rmltest:inputFormat</code>: the input data format.</li>

+<p>This section describes the RML-LV test cases. These descriptions are also available as RDF.
+The files are available on <a href="https://github.com/kg-construct/rml-lv/tree/main/test-cases">GitHub</a> in the folder <code>test-cases</code>.
+Each test case is contained in a single folder, containing three types of files:</p>
+<ul>
+<li>Zero or more files containing the data sources, in the case of JSON, XML, CSV, or containing the SQL statements to create the necessary tables, in the case of MySQL, PostgreSQL, and SQL Server.</li>
+<li>One file with the RML rules, called <code>mapping.ttl</code>, in the Turtle format.</li>
+<li>Zero or more files with the expected RDF. No file is provided if an error is expected that must halt the generation of the RDF because of an error.</li>

+<p>This document defines the RML-LV test cases, consisting of a collection of test case documents (input and expected output).
+The purpose of the test cases is to determine the conformance of tools that execute RML rules to the RML-LV specification.</p>

+<p>The test cases are semantically described for re-usability and shareability following the <a href="https://www.w3.org/2006/03/test-description">W3C Test case description</a>.
+Each <code>test:Testcase</code> as the following properties:</p>
+<ul>
+<li><code>dcterms:identifier</code>: unique ID of the test case.</li>
+<li><code>rmltest:hasError</code>: if an error of the RML Processor is expected or not.</li>
+<li><code>rmltest:input</code>: One or more input data of the test case.</li>
+<li><code>rmltest:output</code>: One or more output data of the test case.</li>

+Each test case is contained in a single folder, containing three types of files:</p>
+<ul>
+<li>Zero or more files containing the data sources, in the case of JSON, XML, CSV, or containing the SQL statements to create the necessary tables, in the case of MySQL, PostgreSQL, and SQL Server.</li>
+<li>One file with the RML rules, called <code>mapping.ttl</code>, in the Turtle format.</li>
+<li>Zero or more files with the expected RDF. No file is provided if an error is expected that must halt the generation of the RDF because of an error.</li>

+# Data model
+
+The test cases are semantically described for re-usability and shareability following the [W3C Test case description](https://www.w3.org/2006/03/test-description).
+Each `test:Testcase` as the following properties:
+
+- `dcterms:identifier`: unique ID of the test case.
+- `rmltest:hasError`: if an error of the RML Processor is expected or not.
+- `rmltest:input`: One or more input data of the test case.
+- `rmltest:output`: One or more output data of the test case.
+- `rmltest:inputFormat`: the input data format.
+- `rmltest:outputFormat`: the output data format.
+- `rmltest:mappingDocument`: the RML mapping rules in Turtle.

+# Introduction
+
+This document defines the RML-LV test cases, consisting of a collection of test case documents (input and expected output).
+The purpose of the test cases is to determine the conformance of tools that execute RML rules to the RML-LV specification.

+# Test cases
+
+This section describes the RML-LV test cases. These descriptions are also available as RDF.
+The files are available on [GitHub](https://github.com/kg-construct/rml-lv/tree/main/test-cases) in the folder `test-cases`.
+Each test case is contained in a single folder, containing three types of files:
+
+ - Zero or more files containing the data sources, in the case of JSON, XML, CSV, or containing the SQL statements to create the necessary tables, in the case of MySQL, PostgreSQL, and SQL Server.
+ - One file with the RML rules, called `mapping.ttl`, in the Turtle format.
+ - Zero or more files with the expected RDF. No file is provided if an error is expected that must halt the generation of the RDF because of an error.
