Its main purpose is to +allow a query for data using logical concepts (e.g. "galaxies", "observation +logs") rather than a specific list of resources. This should limit the +number of resources that need to be queried when querying all data services +and return more relevant results. This is done by using the <I><topic></I> +argument as a keyword search value for the Registry, the resulting resource +list +is then used as input for the VODATA task to query only those resources +returned by the Registry query at the position listed by the <I><object>fP +or <ra> <dec></I> position. As an example, the topic 'AGN' may be used +to query only those resources that claim to have something to do with AGN +as opposed to the many hundreds or thousands more that may not contain data +for that field at all but would be queried anyway using the more generalized +approach of <I>VODATA</I>. +<P> + +The actual effectiveness or suitability of this approach will depend greatly +on the keywords (i.e. <I>topic</I>) chosen and the aims of a specific query. +<P> + +For a complete list of options and a description of the task behavior, see +the <I>VODATA</I> and <I>VOREGISTRY</I> man page. +<P> +<A NAME="lbAF"> </A> +<H2>RETURN STATUS</H2> + +On exit the <B>votopic</B> task will return a zero indicating success, or a +one indicating an error. +<P> +<A NAME="lbAG"> </A> +<H2>EXAMPLES</H2> + +<DL COMPACT> +<DT>1) Query for catalog data of A2712 from Resources related to gravitational lensing:<DD> +<P> +<PRE> + % votopic -t catalog lens A2712 +</PRE> + +<DT>This query is against only 142 services (data found for 128), a similar query against ALL catalog services would require more than 8000 services to be queried.
