cedures, processes and data formats. Hence, Migration Information Systems demand the creation of a dependency between business and information technologies in order for organizations to be able to efficiently main- tain and further support their migration awareness activities. They should allow the abstraction of proprietary applications through the use of adapters, brokers, and Service Delivery Platforms orchestration engines. Thus, the resulting integration architecture will be more robust and extensible, especially with the advent of the open Web Services frame- work and its ability to fully abstract proprietary technology. Research and Standards: The development of synchronous Migration Information Systems is an emerging market and needs close collaboration with relevant stan- dardization bodies and SO they will not only ensure best of breed technologies with a strong focus on European needs, but also that these requirements are translated into globally accepted industry standards. However, private companies are typi- cally compelled by the realities of profit making, while the public sector's organiza- tions do not have such profit-oriented motivations. Essentially, such implementations should adopt peak technologies and worldwide-accepted and mature standards in order to build Enterprise Application Integration (EAI) and technology frame- works, providing advanced added-value electronic migration awareness services according to Software-as-a-Service (SaaS) model. This approach ensures that new technologies come with sustainability insurance for potential investors and com- mercial exploitation. Interoperability at all levels: Achieving interoperability at technological (semanti- cally defined content, interoperable systems and applications), legal (migration- related directives, decisions), and organizational (migration stakeholders) level, among many distributed and heterogeneous enterprise systems, is a difficult task, requiring easily identifiable and publishable services, as well as interfaces for the e
