VOTable

Context

This library aims to provide a simple way to parse and view VOTables. The goal is to make the code reusable and as light as possible.

Usage in command-line interface

1. Reading a VOTable from an XML file

VOtableApp pathToVOTable

• pathToVOTable: The path to your VOTable, ie ~/dowloads/my_votable.xml.

This will display the VOTable stored in the specified XML file, through a minimalist window.

2. Reading a VOTable from an on-line service

VOtableApp targetURL type language query

This will display the VOTable resulting the service or registry request.

• targetURL: The URL of the service or registry to ask, ie http://voparis-tap.obspm.fr/__system__/tap/run/tap;
• language: The language of the query, ie ADQL;
• query: The query in the specified language in double quotes, ie. SELECT TOP 3 * FROM apis.epn_core"

The examples above send this query: http://voparis-tap.obspm.fr/__system__/tap/run/tap/sync?REQUEST=doQuery&LANG=ADQL&FORMAT=votable&QUERY=SELECT%20TOP%201%2A%20FROM%20apis%2Eepn%5Fcore

Usage from a Java library

Here is a start:

VOTableController myVOTableController = new VOTableController(REGISTRY_URL, "ADQL", QUERY);
