<div class="jive-rendered-content"><p>There is always scoping as we need to know how a property specified at the cluster or domain level applies to the server as in the example of system or jvn properties. There its straightforward; the more specific value overrides the more general.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>We have not talked about cluster or admin domain metadata, I mean a, so I view your example as just introducing that notion.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The various domain model elements map onto a ManagedComponent in a way that need to be clearly defined. Logically I stil think about it in terms of scopes that have to be applied to a piece of deployment metadata, and each layer adds the opportunity to specify a default that can be overriden by a more specific value.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So, looking at your little fragment, a clustered-service at at group (which I'm thinking of as admin-domain notion), is a specification of clustering aspects that hae to be applied to a bean or spec component. The resource element is a profile default saying that the profile that maps to the "</p><pre><code>Production</code>" group should include a "<code>Production DB" jca factory.<br/></code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>This is our initial major challenge to moving to the domain model. We need a mapping from domain metadata namespaces onto a ManagedComponent/ManagedProperty. There can be multiple domain metadata namespaces mapping onto a given ManagedComponent/ManagedProperty.</p></div>
