VOTable
The VOTable Working Group is in charge of the VOTable format, which is an XML standard for the interchange of data represented as a set of tables. In this context, a table is an unordered set of rows, each of a uniform format, as specified in the table metadata. Each row in a table is a sequence of table cells, and each of these contains either a primitive data type, or an array of such primitives. VOTable is derived from the Astrores format, itself modelled on the FITS Table format; VOTable was designed to be closer to the FITS Binary Table format.
