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

75 * factory, and perhaps retrieve from the session. We should avoid creating one per request, however.
78 * TODO: Also need to accommodate availability of proxy module
79 * ... could be a different type since we need methods to modify the storage metadata, which would also allow more
80 * appropriate methods to pass in the already determined repository configuration, for example, instead of the ID
