@ -14,14 +14,17 @@ Architecture
Here we describe the rationale behind the architecture :
* Clients perform both CRUD and Query operations against the service both via using the client library or by directly interacting with the service REST interface.
* They interact with the service producing the custom metadata document (stored in a Document Store DB) and registering related Filesets (stored in gCube StorageHub).
* Clients sends steps (pre configured in the collection UCD) requests to the service, which in turn delegate Lifecycle operations to configured implementations.
* Clients may also directly consume materialized projects in ad hoc engines (e.g. SDI or DBMS). For this purpose, the service exposes information needed by the client in order to properly consume the project collection.
In the figure below we further illustrate the various components involved in the typical execution of Projects' lifecycle

Plugin Development support
==========================
In order to facilitate the development of plugins, the following solutions may be of use to the developer :
* extension of an already provided LifecycleManager in order to override default behaviour (e.g. as per *Concessioni* UCD, see suite module concessioni-lifecycle)
* extension of *org.gcube.application.cms.plugins.implementations.AbstractPlugin* class in order to leverage on common behaiovur (e.g. configuration management, error handling)
* extension of *org.gcube.application.cms.caches.AbstractScopedMap* or *org.gcube.application.cms.caches.TimedMap* for easy implementation of caches (respectively by context and global)
* leverage on module *cms-test-commons* for exploitation of context management, basic plugin testing (both static and in a gCube context)
