Hyperlinks in virtual worlds
Hyperlinks are, at present, a novel feature in virtual world platforms, aside from hyperlinks in the in-built chat clients between users' avatars. In the latter 2000s, however, a number of architectures were created for various decentralized virtual world platforms in order to facilitate easier travel of avatars between two or more separately-hosted grids or servers.
Space">SpaceX">Space-linking in OpenCobalt
Open Cobalt uses a method of hyperlinking, known as "space-linking", which resembles a window frame or portal and, when revolved, shows a 360-degree real-time view of one region to a user in another region; such portals can also be walked through by users. Space-linking is an alternative to teleportation, a more common means of traversing between regions or spaces, and is also a primary means of travelling between whole grids.Like MediaWiki's redlinks, such portals are also used to link to uncreated spaces or regions in order to indicate the need to create newer spaces.
