2. What is a Repository?
A Repository is an organisation responsible for conserving
digital material.
– “Conservation” implies a timescale beyond the
limits of current technology
– A repository is not a piece of technology
– ... but it is defined by the challenge of
technological change

3. What is Trust?
Trust is demonstrated organisational fitness for purpose.
– Established as part of relationship between
repository and stakeholders (funding agency,
depositors, users, parent institution etc.)‫‏‬
– A two-stage process: achieving fitness and
demonstrating it
– PLATTER handles the first of these (and
DRAMBORA is concerned with the second)‫‏‬

4. The Road To Trust
There are no widely-accepted standards for trust! What
exists are
– Checklist-based standards (such as nestor and TRAC)‫‏‬
– Flexible toolkits (i.e. DRAMBORA)‫‏‬
– Promising standardisation initiatives (e.g. The Birds of a
Feather Group)‫‏‬
So for any repository, Goal 0 is
– In consultation with stakeholders, establish criteria for trust
PLATTER is a tool to steer a path towards satisfying those criteria.
How do we make a planning tool when we don't what we're
planning for?

5. Scylla and Charybdis
Over-generality Over-specificity
– General-purpose – Inflexible
organisational – Unrealistic
planning tools expectations
– Only useful with – Failure to balance
prior knowledge of costs/benefits
repositories
– Lacking concrete
advice

6. Finding The Middle Way
The PLATTER approach:
– Define general guiding principles (for all
repositories)‫‏‬
– Use these as a basis for repository to set its own
goals
– Provide many examples for repositories to use,
modify, or reject according to their specific mandate
– Use the CRL/DCC/DPE/nestor Ten Core Principles
as a starting point

10. Repository Characterisation
Example
Q1.2 Commercial Status
The functioning of a repository is strongly
constrained by its business status, and specifically
whether it is has a responsibility to further the
financial aims of itself or its parent body .
Is the Repository for profit or non-profit?
