Information on Service 'Validator for IVOA Identifiers'

[Use this service from your browser]

Further access options are discussed below

A validator for IVOA identifiers, checking conformity to version 2 of the specification.

The service returns results in a tabular format, where an identifier is valid if no row with msg_type="ERROR" is present.

As per DALI, the format of the table returned can be controlled through the RESPONSEFORMAT parameter; for machine consumption, the most useful values for that parameter are probably json and votable.

The code used here is available at http://svn.ari.uni-heidelberg.de/svn/gavo/hdinputs/ivoidval
