Updating AIP if overwriting is practically impossible #22

Review comment: Updating AIP conforming e-ark specification: How about a case where AIPs exist in a tape library, but overwriting is practically impossible, since that action reduces the lifecycle of the tapes? Usually changes are saved as physically separate incrementals in this situation.

This is possible by defining an update policy of AIP versions. A new version of the AIP can be held in a life system which contains updated metadata and additional representations. A rule-based merging of the AIP of the life system with the AIP on tape would make this possible.
