+ <p>This exercise deals with executable scripts from different programming
+ languages. You are expected to supply an <a
href="http://www.w3schools.com/schema/default.asp">XSD</a> schema file which
basically allows for defining:</p><ul>
<li>A set of available programming languages</li>
<li>A collection of code fragments (scripts) being related to one or
more programming languages.</li>
- </ul><h1>Preparations</h1><p>Download <a
- href="/files/goik/Sda1/HHg22f+7++QQ-Gcctz3gh/scripts.zip"
- target="_blank">scripts.zip</a> and import it as an Eclipse Maven project
- into your workspace. This project contains a sample data file
- <code>Schema/sampledata.xml</code>.</p><h1>Task</h1><p>Complete the provided
- schema <code>Schema/scripts.xsd</code> file which is yet essentially empty.
- The following constraints shall hold: </p><ul>
- <li>Each programming language name below the global
- <code><languages></code> section must be unique.</li>
+ </ul><h1 id="preparations">Preparations</h1><p>Download <a
+ href="../files/goik/Sda1/HHg22f+7++QQ-Gcctz3gh/exam.zip"
+ target="_blank">exam.zip</a> and unzip it. Then import the resulting
+ <code>Exam</code> directory as a <strong>Maven Eclipse</strong> project into
+ your workspace. Subsequently mentioned relative file and directory path
+ names refer to this project's root.</p><h1>Task</h1><p>Start from
+ <code>Schema/scripts.xsd</code>. Extend this file thereby providing an XML
+ schema grammar implementing the constraints being described in the <a
+ href="#dataModel">Data model description</a> section
+ below.</p><h1>Hints</h1><ul>
+ <li>The sample data file <code>Schema/sampledata.xml</code> illustrates
+ the constraints being described in the <a href="#dataModel">Data model
+ description</a> section below.</li>
+
+ <li><p>The sub directory <code>SchemaTest</code> contains unit tests
+ checking your schema for correctness. Some files contained within must
+ be valid and some must be invalid with respect to your
+ <code>Schema/scripts.xsd</code> implementation.</p><p>You may execute
+ <code>de.hdm_stuttgart.mi.sda1.scripts.SchemaTest</code> from your
+ project's <code>src/test/java</code> branch as a Junit test. If your
+ schema is correct you'll read:</p><pre>++Instance SchemaTest/invalidHasReference.xml: Gaining 1 point.
