/**
* Default implementation of the metadata resolver API. At present it will handle updating the content repository
* from new or changed information in the model and artifacts from the repository storage.
* <p/>
* This is a singleton component to allow an alternate implementation to be provided. It is intended to be the same
* system-wide for the whole content repository instead of on a per-managed-repository basis. Therefore, the session is
* passed in as an argument to obtain any necessary resources, rather than the class being instantiated within the
* session in the context of a single managed repository's resolution needs.
* <p/>
* Note that the caller is responsible for the session, such as closing and saving (which is implied by the resolver
* being obtained from within the session). The {@link RepositorySession#markDirty()} method is used as a hint to ensure
* that the session knows we've made changes at close. We cannot ensure the changes will be persisted if the caller
* chooses to revert first. This is preferable to storing the metadata immediately - a separate session would require
* having a bi-directional link with the session factory, and saving the existing session might save other changes
* unknowingly by the caller.
* <p/>
