High-Level Constructs in the READY Event Notification System (1998)  by Robert E. Gruber, Balachander Krishnamurthy, Euthimios Panagos

From the Introduciton:

There
is growing interest in the use of general-purpose event notification
services as “middleware” for gluing together independently-developed
distributed applications. This approach was first discussed by Oki
et.al.in 1993 [14], where an early version of the (now) TIBCO
Information Bus [20] was described. Since then, many other commercial
products have been developed that accept events from event suppliers
(publishers) and deliver them to event consumers (subscribers). 
Publish-subscribe mechanisms have also been retro-fitted to existing
middleware products, including persistent message queue products and TP
monitors. There is also standards work in this area, including the
CORBAEvent Service [15] and more recently the CORBANotification Service
[16], a feature-enriched version of the Event Service.

Despite all
of these products and the standardization efforts, and despite the fact
that event-driven computation is not a new idea, there has been
relatively little work on high level constructs for event services. The
most basic event service has four kinds of entities (supplier,
consumer, event, event service) and three basic functions (supply an
event to the service, register interest in a kind of event, unregister
interest). Existing commercial event services do not provide event
models that are much richer than this most basic service. For example,
there are typically no constructs that enable operations over multiple
entities.
This paper describes high-level constructs (operating over
multiple events, multiple consumers, etc.) provided by READY, an event
notification system being developed at AT&T Labs [7]. – goto
