The increasing capabilities and quality of information technology has thrown integration endeavour to a top priority (total integration trend). However, the lack of time to mature consensus and the market dynamics, has led to technological dependencies (vendor lock-in). Over the past few years, a variety of new concepts, paradigms, methodologies and technologies have contributed to unique information technology (IT) solutions. One main research question is how to establish an open development landscape for the emergent complex integrated IT system of systems under vendor agnostic models (openness). The Collaborative Enterprise Development Environment (CEDE) is a research effort towards a unified development culture (based on conformity certifications). The strategy is complementary to existing standardizations processes and is based on promoting an open (unified) collaborative development environment.

This paper discusses a collaborative framework for the legal certification of toll enforcement on motorways operated by Brisa Auto-Estradas de Portugal, based on the Advanced License Plate Recognition (ALPR) system/service. The developed ALPR service produces a composite JPEG picture documenting an irregular situation. An enforcement transaction is generated at Brisa’s toll infrastructure and later delivered to the toll clearing company Via Verde Portugal (VVP). This company processes the generated composite picture, matching it with the client data base and, if necessaty, pursuing legal action. The enforcement picture might also be delivered to other organizations, such as the official entity for car registration management, in Portugal the General Direction of Traffic (DGV). Certification is based on Public Key Infrastructure (PKI) and legal digital certificates. Its purpose is to guarantee the validation of an ALPR generated picture as genuine, at a court of law; any change will be detected by a validation service. The paper discusses the adopted strategy, considering not only technical but also organizational issues, since the trust required for the management of enforcement pictures along the involved networked organizations requires a set of procedures to be followed in order to ensure the required legal confidence (trust).

Teaching Web Services concepts, standards and technologies is a difficult and a long process if we have not chosen the right tools [1]. Nowadays there are several open source tools and platforms, but some of them are not suitable to teach.This poster describes our experience by using Microsoft .NET platform and Visual Studio .NET with Web Services Enhancements (WSE) to teach basic Web Services concepts and related technologies.
