Integrating The MACHO Data-set with the Virtual Observatory.
Jonathan G. Smillie, Roberta Allsman, Stuart Hungerford, Jason Ozolins · 2005
A Virtual Observatory (VO) provides enhanced distributed access to online astronomical data-sets, and frequently incorporates data processing and visualisation facilities. Almost all critical aspects of data-grid research and technology are encountered when developing a Virtual Observatory. Issues include interoperability of data-sets and processing software, metadata format standardisation, and resolution of ontological issues. Members of the ANU Supercomputer Facility (ANUSF) are undertaking research and implementation projects in several key VO areas. In this paper we discuss the datasets and astronomy projects with which ANUSF is involved, and outline the VO projects we are undertaking based on these resources.
