regquery: Queries the VO registry
regquery submits a query to the Virtual Observatory
registry
and returns the result as a table containing all the records which
match the condition specified. The resulting table can be written out
in any of the supported formats or otherwise processed in the usual ways.
Making use of this command requires an understanding of the
VOResource schema.
It is important to note that the results of this command give a very much flattened and incomplete view of the results of a full registry query. That is because the contents of an IVOA Registry (see the IVOA Resource Metadata and VOResource documents for more detail) are hierarchical and cannot be faithfully represented in a simple tabular structure. Other superior registry search clients exist; this command is just useful for viewing the results in a rather simplified way which can be represented as a table.
