Using web model feeds to version models which are defined in modeling languages

摘要

Versions of a model in UML or another modeling language can be published on web feeds, such as RSS or Atom web feeds. A model feed includes a sequence of incremental differences to a base version of a model; the base version can be an empty model or a snapshot of another model feed, for example. Stream charts show the relationship between model feeds. A selected sequence of incremental differences can be applied, in forward or reverse, to animate changes in a model. A developer working on a different computer than another developer can create new model versions which use some elements from a published feed and other elements introduced by the local developer. New model versions and semantic information about the sequence taken to reach them can be shared through web feeds.
