Facilitating Co-operation amongst European Public Administration employees through a Unitary European Network Architecture and the use of Interoperable Middleware Components

Objective

The EUPubic project will introduce information technology in order to facilitate inter- European collaboration amongst PA employees. Mature and leading edge information technology solutions in the form of middleware components and Web services will be employed and demonstrated based on a technical architecture referred to as UEN (Unitary European Network). Amongst the important items to be addressed is the conceptual compatibility and homogenization amongst the European PA's in the areas of interest of the user partners of the project. This will be attained through a PA architecture that will address standards as far as content of information is concerned, data integrity, and planning and documentation of processes and data modifications.

OBJECTIVES
The EU-PUBLI.COM project aims at implementing a ""secure Intranet"" that can interconnect at the application level the ISs of public administrations across several European countries. We call this network Unitary European Network (henceforth: UEN). Besides providing the essential interconnection services (e-mail, file transfer, etc.) to administrations by supplying them with basic interoperability tools, the project aims at defining an Unitary European Network Architecture as a whole, by bringing together the collection of distributed, autonomous systems of each administration into a common Cooperative Architecture. In turn, this will make it possible to develop new and reengineer the existing global European administrative processes by making more effective use of the information made available by each individual system.

DESCRIPTION OF WORK
The main pillars of work in the EU-PUBLI.COM project concern the following areas: A. PA employee focus - EU-PUBLI.COM final outcome will be better, faster, and cost effectively served PA employee needs - EU-PUBLI.COM will define a consistent method for organizing and categorizing relevant information, allowing for consistent presentation of this information through the Internet.B. Standardization and Interoperability - The main objective of the EU-PUBLI.COM project is the implementation of a ""secure Intranet"" that can interconnect in the application level the ISs of public administrations across several European countries. C. Development of middleware, distributed systems, multi-layered Web service architectures- Component Transaction Monitors offer both the bus allowing various objects to communicate in a transparent way and a standard component model; it is the middleware layer enforcing the important separation of concerns between the design of added-value, business-aware services and their actual deployment. A CTM defines the framework of services and interfaces on top of which it is effectively possible to develop and deploy software components.- Communication with a Web service shall be using Web protocols, in other words HTTP (& HTTPS) for invoking a particular service. The need for a concerted involvement to engineer interoperability into the enterprise architecture has come under attack recently by advocates of Internet standards such as Web services and XML (Extensive Markup Language); never before has a set of protocols created so much excitement to the industry. However simply providing integration capability to SOAP, WSDL, and UDDI - the three XML protocols that currently define Web services - is not able to facilitate capitalisation on the benefits of the EU-PUBLIC approach, thus ubiquitous XML integration with the UEN component architecture is providing a cost-efficient reality for those industry actors that will invest in them.

The architecture dev eloped in the project is multi-layered: 1. Back-End layer (on the server domain): where the fragmented and vertical legacy data and applications reside. 2. Object Schemas layer (basic components on the server application gateway): implementation of the conceptual model. This layer implements the new cooperative logic by integrating the back-end data to offer the OO schemas. 3. Client view layer this layer implements the "navigation" logic of a particular client organization, by performing seamless access to information collected from the OO schemas. 4. Client application (on the client domain).
