Abstract: A system and method for managing the creation and production of computer generated works permits two or more users to create a work by a collaborative process. The work, or a component of a work, to be created and/or produced is organised into a project structure which includes a plurality of scene structures, each of which can include a plurality of element structures which are used to construct the scenes. A project manager device operates to manage the accessing and modification of elements structures and scenes in the project by the users and manages the relationships between elements structures. The project manager device performs read reference locking of element structures and scenes to ensure that users are always using an appropriate version of the elements and/or scenes and that updates to elements and scenes are correctly propagated to other elements and to users.
