The purpose of the presentation was to introduce some basic digital preservation concepts, such as choosing file formats, file naming best practices, and the basics of preservation metadata. Also discussed were tools and models for managing digital materials. The slides of the talk are available. “File extensions tell computers how to read, open and render files. If a file extension is wrong or missing, your computer will be confused. Digital Preservation is about not confusing your computer.”
