METHODS FOR THE AUGMENTATION, EXPLORATION, AND MAINTENANCE OF PROJECT HIERARCHIES

摘要

A method is provided for graphically representing a portion of a directed acyclic graph as a hierarchical tree structure to facilitate user collaboration over a network, the method comprising obtaining a collaborative project shared among a plurality of users over a communication network, the project represented by a directed acyclic graph structure comprising a plurality of entities and a plurality of associations, the plurality of entities including one or more locus entities, each of the locus entities associated with a locus node from which ancestor entities in the directed acyclic graph of each locus entity are traversed as an inverted tree structure, each child node in the inverted tree indicating a respective entity related as a parent in the directed acyclic graph to the entity of its parent in the inverted tree; and expanding a subtree rooted at a leaf node of the inverted tree in response to user input.
