Why VOTable?
• The VOTable format is an XML representation of
the tabular data (data coming from applications
like BCI suite and NIH online screening center).
• XML format of tabular data can be used for
creating web services Infrastructure.
• Potentially can be used as a
replacement/supplement for CML tables.
• With the use of JAVA Parser API for VOTable,
one can build spread sheet or plotter
applications.

VOTable Tools
 JAVA Parser API: SAVOT (Simple Access to VOTable)
Website: http://cdsweb.ustrasbg.fr/cdsdevcorner/savot.html
 Supports VOTable version 1.0 and 1.1
 Use for reading, writing and modifying VOTable
document
 Provides programming interface to the VOTable data so
one can modify the data, create VOPlot, spread-sheet
like services.
 Visualization Tool for VOTable data – VOPlot

VOTable UseCase Example
• We have a file called “mrtd1.txt” which
includes smiles representation of chemical
compounds along with its properties.
• Next step is to convert this file into
VOTable document (votable.xml) so that it
can be useful for creating voplot
application.

Current and Future Development
• Currently developed VOTableService capable of
retrieving data from votable.xml.
• Enhance the VOTable Service which will be
capable of generating VOPlot from votable.xml
file.
• Write Java Client for the VOTableService which
will be capable of displaying all the data in
meaningful manner (spreadsheet or plot).
