Construction of the Chinese Data-node System for Virtual Solar Observatory

With the multi-waveband observation of the solar and "data avalanche" faced in astronomy and the application of information technologies such as Web Services, the Virtual Solar Observatory(VSO) comes into being. Based on the Web Services, the VSO is an effective tool to resolve the query and download of complicated and abundant solar data. After introducing the implement technology of the VSO to Astronomical field, Spacial physics and Geophysics in China, taking Huairou Solar Observing Staion(HSOS) as an example, a data provider was designed and realized and integrated with the VSO, and this provides a useful instance for other data source about how to integrate with the VSO.
