For successful preservation operations, a preservation system
needs to be capable of monitoring compliance of preservation
operations to specifications, alignment of these operations
with the organisation's preservation objectives, and associated
risks and opportunities. This requires linking a number
of diverse information sources and specifying complex conditions.
For example, the content to be preserved needs to
be related to specifications of significant properties, to the
file formats used to represent that content, to the software
environments available to analyse, render and convert it and
the technical environments available to the designated user
communities that will consume this content.
This article analyses aspects of interest in a preservation
context that call for automated monitoring and investigates
the feasibility of drawing sufficient information from diverse
sources together and linking it in a meaningful way. We
define a number of preservation triggers that lead to preservation
planning activities and present the requirements and
a high-level design of a preservation watch system that is
currently being developed. We demonstrate the value of
such a monitoring approach on a number of scenarios and
