When developing
systematics for the assigning of guarantees of existence several
basic questions need answering. First of all, a decision has to be
made who is able to set guarantees of existence.
The following
three possibilities seem reasonable:
- The
guarantee of existence is set by the author of the text during the
online publishing process.
- Each piece
of information within a pre-defined area (e.g. within a communication
platform) is automatically provided with a pre-defined guarantee of
existence. Either a period of time (e.g. until six months after
publication) or a specific date (e.g. 2005/07/01, end of project)
can be defined.
- A reader,
interested in the information, defines a certain point in time until
which the information should be available. He either sets a new
guarantee of existence or extends the one set by the author (or
another reader). In order to allow the publisher to maintain its
authority as an author to withdraw information, he or she has to be
able to refuse the extension of a guarantee of existence.
