Eco Grid Auth Design

This is version 2. It is not the current version, and thus it cannot be edited.
[Back to current version] [Restore this version]

In order to allow access to private or protected EarthGrid data (via Kepler, for instance) some of the services have been modified.

New search and retrieval methods

EcoGridQuery

authQuery
authGet

These methods take an additional credential parameter. The credential should be returned by a successful call to the EcoGridAuthLevelOneService login method.

Modified Registry Entry records

Currently there is not a good way to associate services that are in the Registry as related to each other. For example, there is no way to explicitly say that "authenticationService123" should be used to authenticate before querying "queryService345". It would be nice to group services that are deployed on the same node as a cluster. A proposed change to the EcogridRegEntryType (xsd):

add 'clusterName' element to each registry entry. It would then be the responsibility of any consuming app (Kepler) to group those for use with a shared authentication service (just another service that is part of the cluster).
