Radio sources study with the virtual observatory tools

During a number of years (1980–1999), using different approaches on the basis of the Virtual Observatory means, the study of sources of the surveys was conducted on the largest Russian radio telescope RATAN-600. Their bulk identification is executedwith themaximumuse of data for different ranges of an electromagnetic spectrumavailable in open access. With the use of the Virtual Observatory program tools, the approach on automatic preparation and preliminary data processing is realized. The information system is developed for the resulting compilative catalogue preparation that was applied in the analysis of information on each source andmaking decision on its identification. Based on the experience gained while working with numerous heterogeneous resources, the author summarizes that the Virtual Observatory infrastructure provides convenient access to astronomical resources and significantly increases the efficiency of scientific research. However, there are still no advanced tools for further analysis, updating and publication of data collected by the researcher. A number of projects is being developed to implement the most linked data based on already existing Web technologies and that will transfer the Virtual Observatory services to a new level of knowledge exchange through annotation of catalogue entries and the implementation of links between them.
