Abstract

The federation of data from distributed locations, different archives and different wavelengths can lead to new discoveries. Moreover, it is an important part of functions of the Virtual Observatory. We review the technical challenges involved in this issue, and develop a system which majors in providing a robust framework to efficiently extract the data from different sources into a science-grade data for the convenient use of astronomers. The system consists of several tasks wrapped together into an integrated framework. The tasks include: the automated creation of database, the rapid query of catalogs, cross-match query and the visualization of the queried results. Especially for cross-matching service, many choices are provided for users, such as one-to-one entry, one-to-many entry, one-to-none entry, none-to-one entry. Meanwhile, the probability of cross-matching is given. In addition, users may select the attributes and the range of attributes according to their requirements. We will further improve the system in various respects according to the standards of the IVOA.
