14.5.5.1 Information Object Dependency Relationships
The information object dependency
relationship connects two information
objects. If preservation action is car-
ried out on one object the impact on
another object with a dependency. For
example if a piece of software is identified
to be at preservation riskand deconstructed
to a structural

descriptions, the software user manual will
be flagged upby the dependency relationship
and maybe removed on the basis that this
information is now irrelevant.

14.6 Preservation Strategy Topics
Once the Information flow diagram has been created an archive must identify
suitable preservation strategies in the following areas.
14.6.1 Strategies in Response to a Supply Impediment
Where there is an impediment to the supply of a required information object,
a strategy must be developed. One may be able to overcome the impediment
immediately or alternatively develop a mechanism that effectively references the
external information object in tandemwith a mechanism for monitoring the situation
(preservation orchestration).
The international workshop on MST radar is held about every 2-3 years, and
is a major event gathering together experts from all over the world, engaged in
research and development of radar techniques to study the mesosphere, stratosphere
and troposphere (MST). It is attended by young scientists, research students and
new entrants to the field to facilitate close interactions with the experts on all tech-
nical and scientific aspects of MST radar techniques. It is this aspect which makes
the proceedings an ideal resource to support future users who are new to the field.
Permanent access to these proceedings is at risk with supply impeded by the dis-
tribution and failure to deposit proceedings in a single accessible institution. The
MST 10 proceedings are available for download from the internet and from the
British Library. Proceedings 3, 5-10 are also available from the British Library,
meeting 4 is only available from the Library of Congress. Unfortunately the
proceedings from meetings 1 and 2 have not been deposited in either institution.
A number of strategies present themselves. Copies of proceedings 1, 2 and 4
could be obtained from the still active community, digitised and incorporated into
the AIP. The proceedings which are currently held by the British Library can
