PhotArk Design

Below you can find a high level design diagram of the PhotArk services. These services are assembled together using SCA and the Apache Tuscany runtime, and then exposed with different bindings to the client applications (e.g JSON-RPC for Web Interface and ATOM Feed binding for integration with other applications/readers)

Gallery Services is a facade that enables application to interact with the different types of albums of a gallery.

Album Services abstracts the operations available for the different types of albums. This should be extensible to allow users/developers to plug support for other types of albums.

Currently there are support for two types of repositories, a plain file system that allows PhotArk application to allow PhotArk to be deployed in constraining environments such as Google AppEngine, and a JCR based repository.
