Paper Abstract

The Japanese Virtual Observatory (JVO) project has been conducted by the National Astronomical Observatory of Japan (NAOJ). JVO aims at providing easy access to federated astronomical databases (especially SUBARU, Nobeyama and ALMA) and data analysis environment using the Grid technology. We defined JVOQL (JVO Query Language) for efficient retrieval of astronomical data from a federated database. We then constructed the first version of the JVO prototype in order to study technical feasibility including functionality of JVOQL, remote operations using Globus toolkit. The prototype consists of several components as follows: JVO portal to accept users' requests described in JVOQL, JVO Controller to parse them into individual query requests, and distributed database servers containing Suprime-Cam data of the Subaru telescope and 2MASS data. We confirmed that this prototype actually worked to access to a federated database. We construct the second version of the JVO prototype system to improve usability, which includes new user interfaces, efficient remote operations, and introduction of analysis tools. In the course of this, Grid service and XML database is employed. In this presentation we describe its design and structure of the new JVO prototype system.
