Path Marking: In order to facilitate professional dialogue and exchange of knowledge through access to a shared information base, it is essential to mark an information path (audit trail) that documents each facet of a particular decision process and the unique perspective of the decision maker (ie. cost effectiveness relative to other possible choices; resource protection; threats to other resources; implications for other resources). Through the process of marking an information retrieval path, the rationale behind the particular decision can be evaluated from the perspective of the decision maker, and results measured against recorded intentions and expectations. This can facilitate assessment and evaluation of individual decisions and result in a greater understanding of the implementation of policies or management tasks by all levels of participants in the preservation process.
