  Virtual Astronomy Multimedia Project (VAMP)
  The Virtual Astronomy Multimedia Project (VAMP) will enable access to, and vastly multiply the use of, astronomy image resources. VAMP will enable innovative future exploitation of all kinds of outreach media by systematically linking resource archives worldwide. VAMP offers a threefold solution to the astronomical community. VAMP manages the Astronomy Visualization Metadata (AVM) standard for astronomical imagery.
