Restrictions for the definition of guarantees of existence are needed
due to several, mainly economic, reasons. Different parameters are
relevant:
- maximum duration for a guarantee of existence
- available memory capacity (disk space)
The process of
deciding on the limits consists, for practical purposes, of two steps:
First, the system operators need to decide how long and to which extent
e-portfolios can and should be available. Only afterwards, owners of
e-portfolios can be provided with guaranteed ressources. Subsequently,
owners can set or extend guarantees of existence within the given
boundaries for content either published by themselves or by other
authors (provided those allow others to set and extend guarantees of
existence).
