Summary on Grant Application Form |
|
Our fundamental assumptions are that a realistic global computation paradigm must incorporate heterogeneity, object orientation and persistence. The ODMGs object definition language (ODL) is a superset of OMGs interface definition language (IDL). IDL achieves inter working between distributed components written in disparate programming languages. ODL unifies this with stored data.Within this framework we shall show how to compose distributed applications using events, through our Publish, register, notify event paradigm. We will develop an event classification hierarchy so that registration of interest with a super-class can be extended to new subclasses within a domain and to unknown subclasses in other domains; thus achieving schema evolution and federation of event systems.We shall design and implement event brokerage gateway services They will discover services which notify events, register and de-register interest as appropriate, assist in event filtering and transport, extend access control as specified by policy. Implementation will be as layer upon layer above dominant platforms such as COBRA, Active X, and JavaBeans. We shall support authoring of applications in a rule based (event-condition-action) declarative language, which includes composite events.
