The AVM scheme supports the cross-searching of collections of print-ready and screen-ready astronomical imagery rendered from telescopic observations (also known as ‘pretty pictures’). The scheme is compatible with the Adobe XMP specification, so the metadata can be embedded within common image formats such as JPEG, TIFF and PNG.
Such images can combine data acquired at different wavebands and from different observatories. While the primary intent is to cover data-derived astronomical images, there are broader uses as well. Specifically, the most general subset of this schema is also appropriate for describing artwork and illustrations of astronomical subject matter.
AVM is a proposed recommendation of the International Virtual Observatory Alliance and was last updated in 2011.
A set of metadata panels that can be added to Adobe Creative Suite 4 applications to allow AVM-compliant metadata to be entered directly into images.
The image gallery for the Spitzer Space Telescope employs AVM within its content management system, and all the images have AVM tags embedded within them.
