7 VOTable Access

VOTable is an XML-based format for storage and transmission of tabular data, endorsed by the International Virtual Observatory Alliance, who make available the schema (http://www.ivoa.net/xml/VOTable/v1.1) and documentation (http://www.ivoa.net/Documents/latest/VOT.html). The current version of STIL provides full support for versions 1.0, 1.1, 1.2 and 1.3 of the format.

As with the other handlers tabular data can be read from and written to VOTable documents using the generic facilities described in Section 3. However if you know you're going to be dealing with VOTables the VOTable-specific parts of the library can be used on their own; this may be more convenient and it also allows access to some features specific to VOTables.

The VOTable functionality is provided in the package uk.ac.starlink.votable. It has the following features:

Most of these are described in subsequent sections.
