1. A system to view and manipulate artifacts at a temporal reference point, comprising: one or more artifact drafts associated with each of a plurality of artifacts, each of said one or more artifact drafts representing a state of the associated artifact at a point in time and one or more commands in a command stack that transformed said each artifact draft's parent into said each artifact draft; a plurality of traceability links and traceability vertices representing connections between said one or more artifact drafts of the plurality of artifacts, wherein a traceability link includes an edge between an artifact draft of an artifact in the plurality of artifacts and an artifact draft of another artifact in the plurality of artifacts, said artifact draft of an artifact in the plurality of artifacts and the artifact draft of another artifact in the plurality of artifacts forming the traceability vertices; a processor; and a module operable to execute on the processor and navigate through said one or more artifacts of the plurality of artifacts from a reference temporal point via the plurality of traceability links.
