The web service capability supports a drill-down into the details of a specific dataset and provides a set of links to the dataset file(s) and related resources. This specification also includes a VOTable-specific method of providing descriptions of one or more services and their input(s), usually using parameter values from elsewhere in the VOTable document. Providers are able to describe services that are relevant to the records (usually datasets with identifiers) by including service descriptors in a result document. http://ivoa.net/documents/DataLink 1.0 links-1.0 An endpoint delivering data links in the format specificed by the Datalink 1.0 specification.
