The Gator Program Interface

(Applications Programming Interface)

This tutorial describes how to use the Gator query engine to submit general queries to source catalogs archived at IRSA through HTTP program interfaces or through a web form.

The Catalog Query Server, CatQuery, describes how to build general catalog queries. In some cases, information on specific catalogs and their attributes is needed to construct the interface. This information is returned by two other servers: CatList returns the list of catalogs archived at IRSA. CatDD generates and displays a database data dictionary for a specific catalog; and data dictionary specifies the attributes of the columns in a catalog.
