The approach suggested in this article gives authors the possibility to
make reliable statements on the availability of published information.
The e-portfolio software basically provides publishers with a kind of
commitment option. This option is a guarantee given be the publisher
that published information is not deleted until a certain period of
time has expired. The metadata of a content object gives information on
the author, the copyright owner, the publication date as well as how
long the information will be available at the respective internet
address which, essentially, needs to stay the same.
Two factors determine whether the concept will work properly: The
assigned guarantee needs to be clearly visible. Moreover, the relation
between the guarantee and the information needs to be obvious. In
addition users need to show confidence in the guarantee. Crucial
factors for confidence are the credibility of the organisation or
institution responsible as well as a logical, transparent method
according to which the guarantee of existence is set.
If credibility and method are accepted by the users, the precondition
for reliable availability of information, as mentioned above, is
fulfilled. In combination with a precise linking mechanism, it becomes
possible to include information reliably into a developing learning
environment, which subsequently turns the e-portfolio into a
sustainably usable knowledge ressource.
