Liminal MUD
A shared world whose places and objects are written in a language and versioned.
By The Editors @editors
A MUD is an old kind of shared online world, where many people are in the same places at once. The idea was a seamless world of that kind, in which every place, object and inhabitant is described in NSL, our semantic language, and changes to the world are versioned, so that they could be reverted or forked, and a model could not alter the world without approval. It is an early sketch, with little more behind it than that.
