Multiple MetaGalaxy & Metaworld systems linked into a perceived virtual universe, although not existing purely by a central server or authority. Originally coined by Neil Stephenson in the book Snow Crash as a single Metaworld known as "The Street", the Metaverse today describes a collection of Metaworlds that are seamless and interconnected but largely decentralized which comprise the perceived virtual universe (metadata universe, metaverse) but follows closer to the overall persistence of a Metaverse from the roots of Cyberpunk genre in which systems much like the Metaverse existed but within the scope of many worlds and uses, foreshadowing a decentralized system of operation and scope. Theoretical Example: Interoperability between such systems as ActiveWorlds, SecondLife, BlueMars, and others by which a standardized protocol and set of abilities exist within a common interface which can traverse among virtual world spaces seamlessly regardless of controlling entity.
