This paper discusses version control for hypermedia models with composite nodes that allow distinct representations of the same information segment to be treated as versions. Several problems arise from the possibility of a node being contained in different nested compositions, as well as being presented (edited) with different representations. The paper discusses these issues, relating partial solutions proposed in several hypermedia models and presenting the proposal defined in the Nested Context Model of the HyperProp system.
