The National Digital Stewardship Alliance has released the National Digital Stewardship Alliance Glossary.
Here's an excerpt from the announcement:
Glossaries are important. . . .
With that in mind, today we're announcing the release of a National Digital Stewardship Alliance glossary to support the work being done in the NDSA on the Levels of Preservation. The Levels of Preservation activity is working to provide basic digital preservation guidance on how an organization should prioritize its resource allocation. The NDSA glossary strives to provide a common language for NDSA members to communicate about the levels work and should also be useful as a general digital stewardship glossary.
