C++ parser for VOTable

This page describes the effort to build a C++ parser for the VOTable XML format as part of the VOI (Virtual Observatory India) project. This project has been undertaken by the Inter-University Centre for Astronomy and Astrophysics and Persistent Systems, Pune.Please send comments and questions to <voindia@vo.iucaa.ernet.in>.

The alpha version of the C++ parser will be available at this site on May 31st,2002.

Salient Implementation Features

• The parser is implemented as a wrapper over XALAN-C++, an XSLT processor and provides for an API based interface to access VOTable files.
• Since XALAN-C++ is a robust implementation of  is a robust implementation of the W3C Recommendations for XSL Transformations (XSLT) and the XML Path Language (XPath), XPath queries can be used to access the VOTable data. As a result future enhancements to the parser can be incorporated quickly and efficiently.

Object Model

Current Scope

• Support only for reading of tables
• Support only for pure-XML TABLEDATA and not for BINARY or FITS data streams
