Assessing the costs of preserving a digital data collection
in the long term is a challenging task. The lifecycle costs
consist of several cost factors. Some of them are difficult
to identify and to break down. In this paper we present
a cost model especially for small scale automated digital
preservation software system.
The cost model allows institutions with limited expertise in
data curation to assess the costs for preserving their digital
data in the long run. It provides a simple to use methodology
that considers the individual characteristics of different
settings. The cost model provided detailed formulas to
calculate the expenses. The model supports the detailed
calculation of the expenses for the near future and helps to
identify the cost trend in the medium and long run (e.g. 5,
10 or 20 years) of the archive. The model monetary assesses
the user´s work, the purchases of storage hardware and other
costs of preserving a digital collection.
In this paper the first version of the model is presented. It
includes a discussion about the cost items and presents the
calculation the costs. A case study shows the application of
the model for a small business setting.
