The LINCKS system also maintains an edit history. This history represents the relation `is used to create'. The relation is a partial order and can relate versions of different objects.
Currently the edit history is maintained by using the SYSTEM:Parent links in the versions. The linkitem in SYSTEM:Parent points to the version which was used to create this version. This link is automatically updated by a CPO_COPYOBJ() command or upon the creation of a new transient version.
