Repository should aspire to make contents accessible and usable over the medium term

A repository should be for content which is required and expected to be useful over a significant period. It may host more transient content, but by and large the point of a repository is persistence. While suggesting a repository should be a "full OAIS" has not proved acceptable to this group so far, investment in a repository and this need for persistence suggest that repository managers should aim to make their content both accessible and usable over the medium (rather than short) term. For the purposes of this exercise, let's suggest factors of around 3: short term 3 years, medium term around 10 years, long term around 30 years plus. Ten years is a reasonable period to aspire to; it justifies investment, but is unlikely to cover too many major content migrations.

 

To achieve this, I think repository management should assess their repository and its policies. Using OAIS at a high level as a yard stick would be appropriate. Full compliance would not be required, but thought to each major concept and element would be good practice.

 

This "idea" is to replace the "full OAIS" approach with something more realistic and achievable.
