g - The blending of Web2.0 components (used for visualization of policy components in government modeling and public debate services) with semantic structures (i.e., migration policies ontologies and taxonomies) is envisaged to be the next generation of services. - The employment of business process management (BPM) [22] techniques for the composition of complex e-government services spanning multiple elementary services that are dispersed both geographically and adminis- tratively fall in the scope of the next generation of composite business Web Services (complex fully fledged SOA environments). The development and integration of an ontology framework and related tax- onomies toward establishing a common understanding of terms and a sharable Participatory Immigration Policy-Making vocabulary of information associated with migration policies will support complex aggregation of data, including conflicting demands, positive and nega- tive opinions, similar expressions, and both open and structured reasoning. The integration of algorithms, patterns, and methodologies for policy deci- sion making and monitoring composes a higher level of intelligence for policy makers, surpassing in effectiveness existing traditional monitoring and har- monization methods. Integrating and properly orchestrating a number of advanced technologies and open-source software components, ImmigrationPolicy2.0 constitutes an innovative revolutionary Migration Information System, able to strengthen operational pan- European cooperation in fight against illegal immigration and the harmonization of policies, taking advantage of the interactive participation both of citizens and immigration stakeholders.
