Digitisation of Records Procedures

Purpose

To describe the process to digitise physical source records with the intention of destroying them after digitisation and retaining the records in electronic form only.

Organisational scope

These procedures apply to all University of Otago staff, including persons contracted to the University either directly or in partnership with it.

The procedures apply to all records owned by the University, which fall under the coverage of the Public Records Act (PRA) 2005 and the Contract and Commercial Law Act (CCLA) 2017.

Definitions

Bit Depth

The number of bits (zeros or ones) used to describe the colour of each pixel. Bit depth can range from 1 bit up to 48 bits. Greater bit depth allows a greater range of colours or shades of grey to be represented by a pixel.

Compression

Compression involves a set of algorithms designed to reduce the size of an image for storage or transmission. Lossless is when no information is irretrievably lost. Objects where lossless compression was applied are identical to the original source after they are un-compressed, i.e. no bits (or information) are lost.

Digitisation

The process of converting hard copy, or other non-digital, records into a digital format.

Metadata

A set of data that describes and gives information about other data.

Quality Assurance

Checking the operation and output of digitisation processes against agreed benchmarks to ensure their authentic reproduction and functional equivalency to the physical source record.

Trusted System

An approved University system or repository that provides reliable data protection consistent with normal and prudent IT practice.

Unique or Rare Information

Information of importance to our national or cultural identity; of historical significance; and of cultural value to Māori and their identity.

Content

1. General provisions

1. Public records can be retained in electronic form only if the digital reproduction demonstrates:
   1. functional equivalency to the physical source record, and
   2. integrity and accessibility managed according to this procedure.
2. Functionally equivalent is when:
   1. the integrity is preserved by remaining complete and unaltered, and
   2. it is readily accessible and usable for as long as is legally and administratively required for subsequent reference.
3. The following records can be fully digitised, but the source records must be retained:
   1. unique or rare information (see the Definitions section for more information), and
   2. all information created prior to 1946.

2. Meeting the conditions to keep records in electronic form only after digitisation

1. The digitised reproductions are to be stored and managed in a trusted University system for the duration of their retention period.
2. The digital reproductions are to be locatable and retrievable through the use of adequate and searchable metadata
3. The Digitisation Checklist must be completed and forwarded to Information Management for retention.

3. Minimum technical specifications

The highest technical specifications that can realistically be supported should be used.

The minimum recommended specifications are:

4. Quality assurance

1. This is achieved through satisfactory completion of the Digitisation Checklist according to the requirements of this procedure.
2. If digitisation is outsourced, quality assurance procedures should be agreed with service providers prior to commencement.
