The Design and Development of Large-scale Catalogue Federation System(XMaS_VO)

The cross-identification of catalogues from different bands, especially from large survey projects, is the bottleneck for multi-wavelength astronomical research in multi-wavelength, especially for data mining and statistical study. We developed and realized a huge multi-wavelength catalogue federation system(XMaS_VO)independent of special databases. XMaS_VO provides catalogue upload and automation of creating databases as well as cross-identification. Since XMaS_VO has good generalization, users can create own databases, and conveniently transplant this system to the local server or their own computers, so that they may implement XMaS_VO by themselves or open such services to others. With the development and deployment of XMaS_VO, astronomers will easily obtain the multi-wavelength federation data they need, therefore more effectively process and analyze large-scale data avoiding the limits of huge volume of data.
