                    <h2>What is Apache Polygene™?</h2>
                    <p>
                        The short answer is that <strong>Apache Polygene™</strong> is a community based effort exploring Composite Oriented Programming for domain centric application development. This includes evolved concepts from <a href="https://en.wikipedia.org/wiki/Aspect-oriented_programming">Aspect Oriented Programming</a>, <a href="https://en.wikipedia.org/wiki/Dependency_injection">Dependency Injection</a> and <a href="https://en.wikipedia.org/wiki/Domain-driven_design">Domain Driven Design</a>.
                    </p>
                    <p>
                        <strong>Composite Oriented Programming</strong> allows developers to work with 'fragments', smaller than classes, and 'compose' fragments into larger 'composites' which acts like the regular objects. Apache Polygene™ also tackles the enforcement of application composition, i.e. composites are declared in modules, modules are contained in layers and access between layers are controlled/enforced.
                    </p>
                    <p>
                        <strong>Apache Polygene™ (Java Edition)</strong>, first Apache Polygene sub-project, is an implementation of Composite Oriented Programming, using the standard Java platform, without the use of any pre-processors or new language elements. Everything you know from Java still applies and you can leverage both your experience and toolkits to become more productive with Composite Oriented Programming today.
                    </p>
                    <p>
                        The Apache Polygene™ community welcomes any effort exploring Composite Oriented Programming for domain centric application development using any technology.

                    <p>Let's create an example application. Open a terminal/console and type;</p>
                    <code><pre>
polygene create-project restapp Order my.domain.order
./gradlew assemble jettyRun
                    </pre>

                    <p>Open <a href="http://localhost:8080/app/api/">http://localhost:8080/app/api/</a> in browser. You will get the REST API root endpoint, showing Customers and Orders.</p>
                    <p>We can navigate to Customers <a href="http://localhost:8080/app/api/customers/">http://localhost:8080/app/api/customers/</a></p>
                    <p>There are no Customers, but instructions how to create one.</p>
                    <p>Open a new terminal and let's create a Customer.</p>
                    <code><pre>
curl -u admin:secret -d name="Niclas Hedhman" http://localhost:8080/app/api/customers/create
                    </pre></code>
                    <p>We get back a confirmation that the Customer was created and the location of </p>

                    <p>
                        The simple Order domain model is found in <code>Order/model/src/main/java/my/domain/order/model/orders</code>
                        and we can see <code>Customer.java</code>, <code>Order.java</code> and <code>OrderItem.java</code>
