Integrating the MACHO dataset with the virtual observatory

Abstract

A Virtual Observatory (VO) provides enhanced distributed access to online astronomical datasets, and frequently incorporates data processing and visualisation facilities. Almost all critical aspects of datagrid research and technology are encountered when developing a Virtual Observatory. Issues include interoperability of datasets 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. Show more
