When a table is saved to VOTable format, a document conforming to the
VOTable specification containing a single TABLE element within
a single RESOURCE element is written.
The version of the VOTable specification according to which the output
is written can be controlled using the
votable.version
system property.
There are a number of variants which determine the form in which
the table data (DATA element) is written:
-
votable-tabledata
- TABLEDATA element (pure XML)
-
votable-binary-inline
- BINARY element containing base64-encoded data within the document
-
votable-binary2-inline
- BINARY2 element containing base64-encoded data within the document.
Not available for VOTable version 1.2 or earlier.
-
votable-fits-href
- FITS element containing a reference to an external newly-written FITS
file (with a name derived from that of the VOTable document)
-
votable-binary2-href
- BINARY2 element containing a reference to an external newly-written
binary file (with a name derived from that of the VOTable document)
Not available for VOTable version 1.2 or earlier.
-
votable-binary-href
- BINARY element containing a reference to an external newly-written
binary file (with a name derived from that of the VOTable document)
-
votable-fits-inline
- FITS element containing base64-encoded data within the document
See the
VOTable specification
for more explanation of what these variants mean.
They can all be read by the
VOTable input handler.
