Detailed Description
MetadataCache manages a cache storage for a set path(), which contains a subdirectory for each registered Metadata item. The cache has a manifest file in its root directory, which lists the version and type of the cache, and all its items. The file is updated automatically when the metadata cache object is destructed, or it can be updated periodically by calling sync().
