+and everything is to be done programmatically, it escalates the need to provide more hands-on explanation of how this is
+done.</p><p>If you want to reproduce what’s explained in this tutorial, remember to depend on the Core Bootstrap artifact:</p><div class="table"><a id="idm522923156656"></a><p class="title"><strong>Table 4. Artifact</strong></p><div class="table-contents"><table summary="Artifact" border="1"><colgroup><col class="col_1" /><col class="col_2" /><col class="col_3" /></colgroup><thead><tr><th align="left" valign="top">Group ID</th><th align="left" valign="top">Artifact ID</th><th align="left" valign="top">Version</th></tr></thead><tbody><tr><td align="left" valign="top"><p>org.apache.polygene.core</p></td><td align="left" valign="top"><p>org.apache.polygene.core.bootstrap</p></td><td align="left" valign="top"><p>3.0.0</p></td></tr></tbody></table></div></div><br class="table-break" /><p>At runtime you will need the Core Runtime artifact too. See the <a class="xref" href="howto-depend-on-polygene.html" title="Depend on Polygene™">Depend on Polygene™</a> tutorial for details.</p><
 div class="section" title="Basics"><div class="titlepage"><div><div><h4 class="title"><a id="_basics"></a>Basics</h4></div></div></div><p>First let’s recap the structural requirements of Polygene;</p><div class="itemizedlist"><ul class="itemizedlist"><li class="listitem">
+There is one and only one Application instance per Polygene™ Runtime.
+</li><li class="listitem">
+Every Application must contain one or more Layers.
+</li><li class="listitem">
+All Composites must be declared in one or more Modules.
+</li><li class="listitem">
+Each Module belong to a Layer.
+</li><li class="listitem">
+Layers are ordered in hierarchies, from simple to complex.
+</li><li class="listitem">
+Access to Composites are limited by visibility rules.
+</li></ul></div><p>Ok, that was quite a handful. Let’s look at them one by one.</p></div><div class="section" title="Application"><div class="titlepage"><div><div><h4 class="title"><a id="_application"></a>Application</h4></div></div></div><p>The first one means that for each Polygene™ Runtime you start, there will be exactly one application. As far as we know, Polygene
+is fully isolated, meaning there are no static members being populated and such.</p></div><div class="section" title="Layers"><div class="titlepage"><div><div><h4 class="title"><a id="_layers"></a>Layers</h4></div></div></div><p>Layers are the super-structures of an application. We have been talking about them for decades, drawn them on paper and
+whiteboards (or even black boards for those old enough), and sometimes organized the codebases along such boundaries.
+But, there has been little effort to enforce the Layer mechanism in code, although it is an extremely powerful
+construct. First of all it implies directional dependency and a high degree of order, spagetti code is reduced if
+successfully implemented. For Polygene, it means that we can restrict access to Composite and Object declarations, so that
+higher layers can not reach them incidentally. You can enforce architecture to a high degree. You can require all
+creation of composites to go through an exposed Factory, which doesn’t require the Composite to be public. And so on.
+Layers have hierarchy, i.e. one layer is top of one or more layers, and is below one or more layers, except for the
+layers at the top and bottom. You could have disjoint layers, which can’t access each other, meaning a couple of layers
+that are both the top and bottom.</p></div><div class="section" title="Modules"><div class="titlepage"><div><div><h4 class="title"><a id="_modules"></a>Modules</h4></div></div></div><p>The Module concept has also been around forever. And in Polygene™ we also makes the Modules explicit. Each Module belong to a
+Layer, and for each Module you declare the Composite and Object types for that Module, together with a Visibility rule,
+one of; application, layer, module.</p></div><div class="section" title="Visibility"><div class="titlepage"><div><div><h4 class="title"><a id="_visibility"></a>Visibility</h4></div></div></div><p>The Visibility rules are perhaps the most powerful aspect of the above. Visibility is a mechanism that kicks in whenever
+a Composite type need to be looked up. It defines both the scoping rules of the client as well as the provider. A lookup
+is either a direct reference, such as</p><pre class="programlisting brush: java">UnitOfWork unitOfWork = module.currentUnitOfWork();
+PersonEntity person = unitOfWork.newEntity( PersonEntity.class );
+</pre><p>or an indirect lookup, such as</p><pre class="programlisting brush: java">UnitOfWork unitOfWork = module.currentUnitOfWork();
+Person person = unitOfWork.newEntity( Person.class );
+</pre><p>where it will first map the Person to a reachable PersonEntity.
+The algorithm is as follows;</p><div class="itemizedlist"><ul class="itemizedlist"><li class="listitem">
+Look in the callers Module, if there is one and only one Composite type matching, use it. If there are two or more
+      Composite types matching, then throw an ambiguity exception. If there are zero, proceed to the next step.
+</li><li class="listitem">
+Look in all Modules in the callers Layer. If there is one and only one Composite type that matches and is either
+      Visibility.layer, then use it.  If there are two or more Composite types matching, then throw an ambiguity
+      exception. If there are zero, proceed to the next step.
+</li><li class="listitem">
+Look in all Layers that caller’s Layer uses. If there is one and only one Composite type that matches and is
+      either Visibility.application, then use it.  If there are two or more Composite types matching, then throw an
+      ambiguity exception. If there are zero, proceed to the next step.
+</li><li class="listitem">
+Throw a CompositeNotFoundException.
+</li></ul></div><p>The underlying principle comes down to Rickard’s "Speaker Analogy", you can hear him (and not the other speakers at the
+conference) because you are in the same room. I.e. if something is really close by, it is very likely that this is what
+we want to use, and then the search expands outwards.</p></div><div class="section" title="Combining The Above"><div class="titlepage"><div><div><h4 class="title"><a id="_combining_the_above"></a>Combining The Above</h4></div></div></div><p>Ok, that was a whole lot of theory and probably take you more than one read-through to fully get into your veins (slow
+acting addiction).
+How to structure your code is beyond the scope of this section. If you are an experienced designer, you will have done
+that before, and you may have started out with good intentions at times only to find yourself in a spaghetti swamp
+later, or perhaps in the also famous "Clear as Clay" or "Ball (bowl?) of Mud". Either way, you need to draw on your
+experience and come up with good structure that Polygene™ lets you enforce.</p><p>So, for the sake of education, we are going to look at an application that consists of many layers, each with a few
+modules. See picture below.</p><p>Image of Example of Layers</p><p>Figure 1. Example of Layers</p><p>So, lets see how we code up this bit in the actual code first.</p><pre class="programlisting brush: java">public class Main
+{
+    private static Energy4Java polygene;
+    private static Application application;
+
+    public static void main( String[] args )
+            throws Exception
+    {
+        // Bootstrap Polygene Runtime
+        // Create a Polygene Runtime
+        polygene = new Energy4Java();
+
+        // Instantiate the Application Model.
+        application = polygene.newApplication(
+            factory -&gt;
+            {
+                ApplicationAssembly assembly = factory.newApplicationAssembly();
+                LayerAssembly runtime = createRuntimeLayer( assembly );
+                LayerAssembly designer = createDesignerLayer( assembly );
+                LayerAssembly domain = createDomainLayer( assembly );
+                LayerAssembly messaging = createMessagingLayer( assembly );
+                LayerAssembly persistence = createPersistenceLayer( assembly );
+
+                // declare structure between layers
+                domain.uses( messaging );
+                domain.uses( persistence );
+                designer.uses( persistence );
+                designer.uses( domain );
+                runtime.uses( domain );
+
+                return assembly;
+            } );
+
+        // We need to handle shutdown.
+        installShutdownHook();
+
+        // Activate the Application Runtime.
+        application.activate();
+    }
+
+      [...snip...]
+
+}
+
+</pre><p>The above is the basic setup on how to structure a real-world applicaton, unless you intend to mess with the
+implementations of various Polygene™ systems (yes there are hooks for that too), but that is definitely beyond the scope of
+this tutorial.</p><p>Now, the createXyzLayer() methods were excluded to keep the sample crisp and easy to follow. Let’s take a look at what
+it could be to create the Domain Layer.</p><pre class="programlisting brush: java">private static LayerAssembly createDomainLayer( ApplicationAssembly app )
+{
+    LayerAssembly layer = app.layer("domain-layer");
+    createAccountModule( layer );
+    createInventoryModule( layer );
+    createReceivablesModule( layer );
+    createPayablesModule( layer );
+    return layer;
+}
+
+</pre><p>We just call the layerAssembly() method, which will return either an existing Layer with that name or create a new one
+if one doesn’t already exist, and then delegate to methods for creating the ModuleAssembly instances. In those method
+we need to declare which Composites, Entities, Services and Objects that is in each Module.</p><pre class="programlisting brush: java">private static void createAccountModule( LayerAssembly layer )
+{
+    ModuleAssembly module = layer.module("account-module");
+
+    module.entities(AccountEntity.class, EntryEntity.class);
+
+    module.addServices(
+            AccountRepositoryService.class,
+            AccountFactoryService.class,
+            EntryFactoryService.class,
+            EntryRepositoryService.class
+    ).visibleIn( Visibility.layer );
+}
+
+</pre><p>We also need to handle the shutdown case, so in the main() method we have a installShutdownHook() method call. It is
+actually very, very simple;</p><pre class="programlisting brush: java">private static void installShutdownHook()
+{
+    Runtime.getRuntime().addShutdownHook( new Thread( new Runnable()
+    {
+        public void run()
+        {
+            if( application != null )
+            {
+                try
+                {
+                    application.passivate();
+                }
+                catch( Exception e )
+                {
+                    e.printStackTrace();
+                }
+            }
+        }
+    }) );
+}
+</pre><p>This concludes this tutorial. We have looked how to get the initial Polygene™ runtime going, how to declare the assembly
+for application model creation and finally the activation of the model itself.</p></div></div><div xmlns="" xmlns:exsl="http://exslt.org/common" class="footer"><p>

+going to show how.</p><p>If you want to reproduce what’s explained in this tutorial, remember to depend on the Core Bootstrap artifact:</p><div class="table"><a id="idm522922591312"></a><p class="title"><strong>Table 13. Artifact</strong></p><div class="table-contents"><table summary="Artifact" border="1"><colgroup><col class="col_1" /><col class="col_2" /><col class="col_3" /></colgroup><thead><tr><th align="left" valign="top">Group ID</th><th align="left" valign="top">Artifact ID</th><th align="left" valign="top">Version</th></tr></thead><tbody><tr><td align="left" valign="top"><p>org.apache.polygene.core</p></td><td align="left" valign="top"><p>org.apache.polygene.core.bootstrap</p></td><td align="left" valign="top"><p>3.0.0</p></td></tr></tbody></table></div></div><br class="table-break" /><p>At runtime you will need the Core Runtime artifact too. See the <a class="xref" href="howto-depend-on-polygene.html" title="Depend on Polygene™">Depend on Polygene™</a> tutorial for
  details.</p><div class="section" title="We need a Service"><div class="titlepage"><div><div><h4 class="title"><a id="_we_need_a_service"></a>We need a Service</h4></div></div></div><p>To illustrate these features we create an TravelPlan service, which allows clients to find and make Reservations to
+Destinations. For the sake of simplicity, we are leaving out the domain details…</p><pre class="programlisting brush: java">public interface TravelPlan
+{
+    // Domain methods, which are beyond the discussion at hand.
+}
+</pre><p>So, then there is the ServiceComposite…</p><pre class="programlisting brush: java">// The package is relevant to the Initial Values discussed later.
+package org.apache.polygene.manual.travel;
+  [...snip...]
+
+@Mixins( { TravelPlanMixin.class } )
+public interface TravelPlanService extends TravelPlan
+{}
+</pre><p>And then in the Mixin we actually need to connect to a foreign system to obtain the various details that the service
+can provide to the clients. For instance, it needs a host name and port and a protocol to use. We put these into a
+configuration interface.</p><pre class="programlisting brush: java">public interface TravelPlanConfiguration
+{
+    Property&lt;String&gt; hostName();
+
+    @Range( min=0, max=65535 )
+    Property&lt;Integer&gt; portNumber();
+
+    @Matches( "(ssh|rlogin|telnet)" )
+    Property&lt;String&gt; protocol();
+}
+</pre><p>We used the recommended type-safe Property subtype pattern, and for each PortNumber and Protocol we have defined a
+Constraint required.</p><p>Now we can access this configuration in the TravelPlanMixin like this;</p><pre class="programlisting brush: java">import org.apache.polygene.api.configuration.Configuration;
+
+public class TravelPlanMixin implements TravelPlan
+{
+    @This
+    Configuration&lt;TravelPlanConfiguration&gt; config;
+
+    private void foo()
+    {
+        TravelPlanConfiguration tpConf = config.get();
+        String hostName = tpConf.hostName().get();
+        // ...
+    }
+      [...snip...]
+
+}
+</pre><p>And from the Service point of view, it doesn’t need to worry about where the configuration really comes from. But it may
+want to control when the Configuration should be refreshed, to ensure that atomic changes are happening. This is done
+with the refresh() method in the Configuration interface;</p><pre class="programlisting brush: java">public void doSomething()
+{
+    // Refresh Configuration before reading it.
+    config.refresh();
+
+    TravelPlanConfiguration tpConf = config.get();
+    // ...
+}
+</pre><p>This ensures that any updates to the Configuration that has occurred will be retrieved and available to the Service.
+Since Configuration instance is an Entity, the UnitOfWork system will ensure that the Configuration is consistent and
+not in the middle of value changes.</p><div class="section" title="Initial Values"><div class="titlepage"><div><div><h5 class="title"><a id="_initial_values"></a>Initial Values</h5></div></div></div><p>The initial Configuration instance will be created automatically behind the scenes, by reading a properties file and
+create an Entity with the same identity as the identity of the service. That was a handful. Services are, as we know,
+singletons and have an identity specified at assembly. Even if it is not provided, one will automatically be assigned.
+The service’s "identifiedBy" will be used as the identifier for the Configuration entity and stored in the visible
+EntityStore. This identity is also used to locate a properties file in the same package as the ServiceComposite belongs
+to.</p><p>So, we create a properties file, where the keys are the names of the properties in TravelPlanConfiguration.</p><pre class="programlisting brush: bash"># Hostname to the TravelPlan service
+hostName=niclas.hedhman.org
+
+# Port number to use for the connection
+portNumber=5439
+
+# Protocol to use; Valid options "ssh", "rlogin", "telnet"
+protocol=ssh
+
+</pre><p>File: org/hedhman/niclas/travel/TravelPlanService.properties</p><p>Note that the file resides in the directory equivalent to the package name of the TravelPlanService.</p><p>And this would work with the standard assembly.</p><pre class="programlisting brush: java">@Override
+public void assemble(ModuleAssembly module)
+{
+    module.addServices(TravelPlanService.class).instantiateOnStartup();
+}
+</pre></div></div><div class="section" title="Non-default Identity"><div class="titlepage"><div><div><h4 class="title"><a id="_non_default_identity"></a>Non-default Identity</h4></div></div></div><p>If you need to use multiple instances of the same service, or that the service has a non-default Identity, then you need
+to name the properties file according to the Identity of the service declaration, but the file will still need to be in
+the same package as the ServiceComposite sub type, the TravelPlanService in the above example. For instance;</p><pre class="programlisting brush: java">@Override
+public void assemble(ModuleAssembly module)
+{
+    module.addServices(TravelPlanService.class)
+            .instantiateOnStartup()
+            .identifiedBy("ExpediaService");
+
+    module.addServices(TravelPlanService.class)
+            .instantiateOnStartup()
+            .identifiedBy("OrbitzService");
+}
+</pre><p>And the two files for configuration,</p><pre class="programlisting brush: bash"># Hostname to the TravelPlan service
+hostName=expedia.hedhman.org
+
+# Port number to use for the connection
+portNumber=9251
+
+# Protocol to use; Valid options "ssh", "rlogin", "telnet"
+protocol=ssh
+</pre><p>File: org/apache/polygene/manual/travel/ExpediaService.properties</p><pre class="programlisting brush: bash"># Hostname to the TravelPlan service
+hostName=orbitz.hedhman.org
+
+# Port number to use for the connection
+portNumber=7412
+
+# Protocol to use; Valid options "ssh", "rlogin", "telnet"
+protocol=rlogin
+</pre><p>File: org/apache/polygene/manual/travel/OrbitzService.properties</p></div><div class="section" title="Changing Configuration in runtime"><div class="titlepage"><div><div><h4 class="title"><a id="_changing_configuration_in_runtime"></a>Changing Configuration in runtime</h4></div></div></div><p>Unlike most frameworks, the Configuration in Polygene™ is an active Entity, and once the properties file has been read once
+at the first(!) startup, it no longer serves any purpose. The Configuration will always be retrieved from the
+EntityStore. Changes to the properties file are not taken into consideration if the Configuration entity is found in the
+entity store.</p><p>But that also means that applications should not cache the configuration values, and instead read them from the
+Configuration instance every time needed, and do a refresh() method call when it is safe to update the Configuration
+Entity with new values.</p></div></div><div xmlns="" xmlns:exsl="http://exslt.org/common" class="footer"><p>
