Multiple Endpoints


As requested in ticket The Top-BDII needs the URL of each service endpoint's GRIS in order to retrieve information about the endpoint. The GRIS URL for each endpoint is to be stored in GOCDB.

To achieve this we propose adding support for multiple <Endpoint> elements per service (the Endpoint element in turn wraps a <URL>). For example, one Endpoint could define the actual service URL, a second could define the GRIS URL, whilst a third could define an Endpoint URL for the admin portal of that service and so on.

Given that a Service would be able to define multiple endpoints, a mechanism is required to distinguish between those different endpoint types and their intended purpose using a known interface name:

  1. As per GLUE2, Define a new <InterfaceName> tag as a child of <Endpoint>. For example, the Endpoint could define the service's GRIS URL with a <InterfaceName> value of "RIS" for Resource Information Service). Preferred.

Adding multiple Endpoints per service is a more GLUE2 centric approach. Additional elements/attributes can be added to the GOCDB Endpoint if required. We may change the 'InterfaceName' element with a more suitable alternative or use a sub-type or attribute (still to decide). For more GOCDB/GLUE2 comparisons see GOCDB/Release4/Development/GLUE2Compatibility.


When adding or editing a service we propose that a user can add multiple child Endpoint objects.

The GOCDB-PI output will be extended to show multiple <Enpoint> elements (each nesting the child <URL> and e.g. the <InterfaceName>). Using this mechanism the Top-BDII can retrieve a filtered list of endpoints that have a URL with the requied classification (e.g. "RIS").
