Abstract: In one embodiment, a computer system performs a method for providing repository item information from one or more different perspectives using virtual repository items within a customizable presentation scheme. A computer system accesses a user-defined presentation scheme that describes a manner in which repository items are to be presented. The computer system generates virtual repository items for actual repository items based on the user-defined presentation scheme. The virtual repository items are generated for presentation along with their actual repository items. The computer system maps the virtual repository items to different virtualized sets of repository items according to the user-defined presentation scheme. The virtualized sets comprise at least one of actual repository items and virtual repository items. The computer system presents the virtualized sets of repository items in one or more different perspectives within the user-defined presentation scheme.
