Cost/benefit data collection and modelling

The data holders in the consortium encompass a wide variety of repositories and cost drivers. Many of the cost models which have been published are based on a library model with a limited number of parameters collected. Another model collected a very large number of cost parameters. This limited the ability to produce an explicit model of cost dependencies (because there were many more parameters collected for each repository than there were repositories providing data and therefore the number of degrees of freedom was too limited), nevertheless they used a technique of finding similarities for any new proposed repository. Even so, limited attention was paid to do anything other than bit preservation and access; the requirements for preserving the usability of the information were not part of the costings.

APARSEN will collect cost structural data among Network partners to develop a summary report on the effect of the various parameters to be able to model Digital Preservation costs, predictions and repository data.
