Glossary of Digitization Terms


Introduction


When beginning your Digitization (DiGI) project, there might be a lot of new terms and words related to the work you have been tasked to do. As you start and become more comfortable with the devices in your project and workflow, these terms will be continue to appear and be frequently used by your team and yourself.

This page features a general glossary of terms that you will likely come across throughout your DiGI project and also the archiving and preservation fields in general. It will be helpful to familiarize yourself with these words and concepts for the future.

This vocabulary is also applicable outside of digitization, so you will also find that you may have a better understanding of musical equipment, general computing, and IT after acquainting yourself more with these words.

This is a living list of definitions and descriptions. If you encounter terms that are unlisted here, or think that more descriptions should be added, please contact the DiGI Team or comment below on this page to have them included in this growing glossary.

Arrangement

Arrangement strategy, order

The organization of processed materials in a collection and archive usually by provenance (see Common Archiving Terms on Provenance) or sequence of acquisition/original creation

Arrangements also do not have to be based off these principles, but can be organized to facilitate searchability of users or designed using Indigenous principles and groupings

Archive

Language archive, data archive, repository

A storage space and system that possess a variety of language materials, organized in collections; archives are long-term storage strategies generally for primary documents and other original resources

Analogue
