The seminar presents the Government-Enterprise Ecosystem Gateway (G-EEG) - a communication/ coordination framework through which multi-organizational processes and applications can dynamically build, apply and evolve complex communication structures, enabling asynchronous exchange of messages in various application contexts. Particular application context is Electronic Government, specifically the delivery of Electronic Public Services through technology-enabled collaborations between private- and public-sector organizations.

G-EEG comprises three components:

1. G-EEG-CORE - a core run-time framework providing basic communication services on top of a plain messaging middleware,
2. G-EEG-EXTEND - a repository of horizontal (process-independent) and vertical (process-dependent) extensions, along with a mechanism to dynamically enable such extensions on top of G-EEG-CORE, and
3. G-EEG-DEVELOP - a development framework to rigorously specify, design, compose and verify messaging extensions.

The seminar presents the motivation for G-EEG and explains conceptual and formal models underpinning G-EEG-CORE and G-EEG-EXTEND, defined in terms of RSL - The RAISE Specification Language. The seminar also demonstrates an example implementation of G-EEG, part of e-Macao Software Infrastructure for Electronic Government.
