Catalogue Brokering Service

This is a testbed for the eSTAR Project's REST catalogue search service (a SOAP service is also available). The eSTAR service acts as a broker layer between the various available SOAP and REST services, allowing the end user to download catalogues from a single source. The service will also parse the catalogues from the 3rd party services, returning them in a variety of user specified formats.

SOAP Service Documentation

Complimenting the REST service is an RPC style SOAP service. The SOAP service will automatically query the CDS Sesame service to resolve target names before making a cone search query using the returned R.A. and Dec. on the requested catalogue. Errors will raise a SOAP Exception which will be returned to the client code.
