Several people have asked for a demo of how collections external to MDID 3 will be searched. The video below shows an example using the NASA Image eXchange (NIX) collection.
After running a search on "Titan", result counts from Flickr, ARTstor and NIX are displayed. Opening up the NIX screen, any record can be selected and immediately added to a presentation or viewed in detail. Flickr will work in the same fashion. ARTstor images can only be displayed as thumbnails until they are imported into MDID 3 manually, and of course an ARTstor subscription is required.
