USC-1 Establish a system of control

An institution establishes its arrangement policy and customizes the application to implement it.

Scenario A:

1. Institution establishes the highest level of arrangement it will employ.

• E.g. Fonds, series, record group established as highest level.

2. Institution establishes the number of levels of arrangement it will employ.

• E.g. no sub-fonds, no more than three series levels (series, sub- and sub-sub-series).

3. Administrator edits the default "Levels of description" taxonomy shipped with ICA-AtoM, so that drop-down lists show only levels and terms allowed by policy.

Scenario B:

Institution changes policy and for a transitional period retains old data values in the application (pending conversion) but allows users to use only new values.

• E.g. application contains descriptions registered as "Record group" but term no longer allowed for new descriptions.

As of version 0.6, ICA-AtoM cannot accommodate this scenario. A term cannot be deleted from a taxonomy if other records are already registered to it. In a future release, it will be possible to make taxonomy terms "inactive" so that data integrity is protected, while drop-down list for on-going data entry show only the preferred terms.
