Item History

Note: There is a newer version of this specification see VEC 2.0.1

Item History

In a development process items (parts or documents) are often refined incrementally, so one ItemVersion originates from another. The class ItemHistoryEntry enables the description of predecessor / successor relationships between ItemVersions. The description of both linear and branching relationships is possible. The relationship can be classified in order to distinguish between two cases:

  1. The successor ItemVersion is an instance of the same item (type = "Sequence")
  2. The successor ItemVersion is an instance of a new but somehow similar item (type = "derivation").
