       stilts-regquery - Queries the VO registry


       stilts regquery [query=<value>] [regurl=<url-value>] [soapout=<out-file>] [ocmd=<cmds>]
                       [omode=out|meta|stats|count|cgi|discard|topcat|samp|tosql|gui] [out=<out-
                       table>] [ofmt=<out-format>]


       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.


              Text  of  an ADQL WHERE clause targeted at the VOResource 1.0 schema defining which
              resource records you wish to retrieve from the registry. Some examples are:

                * @xsi:type like '%Organisation%'

                * capability/@standardID  =  'ivo://'   and   title   like

                * curation/publisher like 'CDS%' and title like '%galax%'

              A  full  description of ADQL syntax and of the VOResource schema is well beyond the
              scope of this documentation, but in general  you  want  to  use  <field-name>  like
              '<value>'  where  '%'  is  a  wildcard  character. Logical operators and and or and
              parentheses can be used to group and combine expressions. To work out  the  various
              <field-name>s you need to look at the VOResource 1.0 schema; you can find some more
              discussion in the documentation of the NVO IVOARegistry package.

              Some known suitable registry endpoints at time of writing are




              If  set to a non-null value, this gives the destination for the text of the request
              and response SOAP messages. The special value "-" indicates standard output.

              Specifies processing  to  be  performed  on  the  output  table,  after  all  other
              processing  has  taken  place.  The  value  of this parameter is one or more of the
              filter commands described in SUN/256. If more than  one  is  given,  they  must  be
              separated  by  semicolon  characters (";"). This parameter can be repeated multiple
              times on the same command line to build up a list of processing steps. The sequence
              of commands given in this way defines the processing pipeline which is performed on
              the table.

              Commands may alteratively be supplied in an external file, by using the indirection
              character  '@'. Thus a value of "@filename" causes the file filename to be read for
              a list of filter commands to execute. The commands in the file may be separated  by
              newline characters and/or semicolons, and lines which are blank or which start with
              a '#' character are ignored.

              The mode in which the result table will be output. The default mode is  out,  which
              means  that  the  result  will  be  written as a new table to disk or elsewhere, as
              determined by the out and ofmt parameters. However, there are other  possibilities,
              which correspond to uses to which a table can be put other than outputting it, such
              as displaying metadata, calculating statistics, or populating a  table  in  an  SQL
              database.  For  some  values of this parameter, additional parameters (<mode-args>)
              are required to determine the exact behaviour.

              Possible values are

                * out

                * meta

                * stats

                * count

                * cgi

                * discard

                * topcat

                * samp

                * tosql

                * gui
               Use the help=omode flag or see SUN/256 for more information.

              The location of the output table. This is usually a filename to write to. If it  is
              equal  to  the  special value "-" (the default) the output table will be written to
              standard output.

              This parameter must only be given if omode has its default value of "out".

              Specifies the format in which the output table will be written (one of the ones  in
              SUN/256 - matching is case-insensitive and you can use just the first few letters).
              If it has the special value "(auto)" (the default), then the output  filename  will
              be examined to try to guess what sort of file is required usually by looking at the
              extension. If it's not obvious from the filename what output format is intended, an
              error will result.

              This parameter must only be given if omode has its default value of "out".
