E-portfolio systems which should work efficiently in the long term need
to cover the complete content life cycle In many cases, the phase of
deleting content is considered either too late or too little.
An environment with guarantee of existence offers new perspectives for
intelligent deleting methods. Unused information can easier be
identified and deleted, linked information be held available. For
instance, owners of e-portfolios can retrieve all information objects
with expired guarantee of existence. A ranking which illustrates the
degree of interconnection and thus the relevance (see above), allows
users to delete unimportant content systematically. Based on this
principle, automatic deleting mechanisms could be developed in the
future.
