 The IDE operates on its source code files in a versioned repository to manage evolution of the Lively code base.The same approach has been used to empower users with control over active web content in the form of a client-side Wiki.Because Lively includes facilities to edit the content in its worlds (scene graphs and other content), and to store that content as web pages, a WebDAV connection allows Lively to store new versions of its page content while it is being incrementally developed.
