<h3 id="overall-structure">Overall structure<a class="headerlink" href="#overall-structure" title="Permanent link">&para;</a></h3>
<p>The Aries project is a collection of loosely couple bundles, therefore
it must be possible to build each bundle on its own. This implies:</p>
<ol>
<li>A parent pom that isn't at the root of the SVN trunk.</li>
<li>Each bundle has enough pom info so that it can be released
independently.</li>
<li>parent/default-parent has dependency management for basic osgi-dependencies that
all projects are almost certain to use (this includes PAX dependencies for
testing).</li>
<li>Each bundle has legal files in its checkout root.</li>
<li>Each bundle has an SCM element in its top level pom.</li>
<li>Bundles do not (except samples) have sub-modules.</li>
</ol>

<h3 id="good-practice-in-the-pom">Good practice in the pom<a class="headerlink" href="#good-practice-in-the-pom" title="Permanent link">&para;</a></h3>
<ol>
<li>Alphabetic ordering in dependency management is helpful</li>
<li>Include a brief description of the project</li>
<li>Commenting in platform dependencies, see samples assembly projects.</li>
<li>Use ${project.version} <em>not</em> ${version} for Maven 3 compatibility.</li>
</ol>

<h3 id="group-and-artifact-names">Group and Artifact names<a class="headerlink" href="#group-and-artifact-names" title="Permanent link">&para;</a></h3>
<ol>
<li>The Bundle Symbolic Name is explicitly set to the Maven artifactId. For
projects which deliver bundles, the artifactID will therefore completely
describe the jar and must begin org.apache.aries.{subproject}. For
projects which do not deliver bundles (for example agregator projects) it
is acceptable to use a short descriptive artifactID.</li>
<li>The group ID will overlap with the artifactId and will normally be of the
form org.apache.aries.{subproject}</li>
