Abstract

We have developed a VO service toolkit to enable astronomical datasets
searchable and accessible through the VO standard interfaces.

Currently our toolkit supports the following VO interface standards:

- Simple Image Access Specification Version 1.0,
- Simple Spectrum Access Version 1.1,
- Table Access Protocol Version 1.0.

Using this toolkit, the following data resources have been made accessible with
the VO standard interfaces:

- Subaru Suprime-Cam archive (TAP/SIA)
- Subaru MOIRCS archive (TAP/SIA)
- Subaru HDS archive (TAP/SSA)
- Subaru Deep Survey (SDF, SXDS) (TAP/SIA)
- AKARI DR1 (TAP)
- IRSF LMC survey (TAP/SIA)
- Kiso UV-X Galaxies Catalog (TAP)
- Stellar Abundances for Galactic Archeology Database (TAP)
- etc...

TAP interface is used as a general access interface for any data type (catalog,
image, spectrum), and queries through the three different interfaces are
processed within the toolkit by a common query executor.

Our toolkit is developed based on Java, and is composed of the following
components:

- HTTP interface based on Apache tomcat,
- ADQL parser written in JavaCC,
- ADQL Translator into DBMS native SQL,
- VOTable generator that converts JDBC ResultSet into a VOTable,
- Table/Column metadata editor,
- Image cutout engine,
- etc...

In this paper, its detailed architecture of our toolkit is presented.
