A metaverse, by definition is a virtual world. Think of a metaverse in the general sense of IAM to be a blank database (or in the case of Novell IAM products a Blank eDirectory), however after you fill it with data its like an authority, in the sense that the data that is in the Metaverse is (after rules have been run on it) the data which is authoritive for other systems, after all you rules are run you would then sync back Certain attributes with your Active Directories, LDAP Directories or your SQL Server.
