Astronomy Visualization Metadata (AVM) is a standard for tagging digital astronomical images stored in formats such as JPEG, GIF, PNG and TIFF.
AVM could be considered analogous to the FITS headers associated with raw astronomical data files.
[3] Software packages such as PinpointWCS,[4] FITS Liberator[5] and Microsoft WorldWide Telescope have implemented the standard.
AVM was conceived by Robert Hurt, Lars Lindberg Christensen, and Adrienne Gauthier.
The Astronomy Visualization Metadata standard defines a taxonomy for astronomical objects.
