The SAMI Data Archive: A Prototype of An Archive of the Future?

Astronomy data sets are not simply exploding in size – they are exploding in complexity too. Witness the data sets obtained from integral-field spectroscopy (IFS).  While the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) survey has exceeded measurements of 1,000 galaxies, surveys such … Continue reading
