DataLink

This FAIRsharing record describes: The DataLink specification defines mechanisms for connecting metadata about discovered datasets to the data, related data products, and web services that can act upon the data. DataLink is a data access protocol in the IVOA architecture whose purpose is to provide a mechanism to link resources found via one service to resources provided by other services. 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.
