<div class="jive-rendered-content"><p>Here is an initial example of the domain.xml effort. The notion is  that the domain.xml is a static metadata model of an API for configuring  the server. This can be use for a rest client, command line client,  junit client, etc.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The relatively easy part is deciding what features we  want to support via the model. The issues to resolve are how to:</p><p>1. Map this metadata onto the admin API of the profileservice. In  general the domain.xml is a subset of the full metadata the service  supports. The ManagedComponent view of the deployment metadata is the  full featured configuration.</p><p>2. Provide a plug in to handle the  mapping of the domain.xml metadata onto the ManagedComponent associated  with the domain.xml element namespace. Currently the ManagedComponent is  a view that is generated after deployment.</p><p>3. Deal with the different mechanisms for producing the runtime  components from metadata. Some layers are using BeanMetaDataFactorys,  jboss-managed plugins, custom deployers to manipulate metadata. Pulling  in the domain.xml element override at the correct phase in the  deployment chain is an issue.</p><p>4. Dealing with rollbacks of the domain.xml if we allow direct  editing of the a domain.xml file. If the domain.xml is essentially a  subset of admin edits of the available ManagedComponents, a rollback  needs to write out a revised domain.xml that corresponds to the previous  subset view.</p><p style="min-height: 8pt;
