The original plan was to allow each system to have customizable lists of metadata, which made constructing metadata really painful (the declaration list isn't stored on the metadata instance because that's pretty wasteful for 2,000 games). Now they're constructed by passing a MetaDataListType enum in the constructor. Declaration lists are now managed by const globals passed by reference through getMDDByType(MetaDataListType).
