Abstract: An object-oriented computer environment is managed by storing, in a plurality of repositories accessible during the life cycles of objects, information required to initiate object operations. The repositories can contain location information identifying the storage location of system objects or information indicating preferences for a preselected manner of performing object operations. In another preferred form, the repositories can be assigned to different levels of a hierarchy to control the distribution of stored information.
