FP6 ECOSPACE “eProfessional Collaboration Space” (https://cordis.europa.eu/project/id/035208). ECOSPACE targets the conception and development of a Collaborative Working Environment supporting seamless collaboration among knowledge workers, especially eProfessionals. ECOSPACE has 4 main objectives: i) The definition of innovative work paradigms through the analysis of eProfessionals and their related organisation. ii) The design and development of an open standards service-oriented architecture for complementary and alike systems. iii) A collaboration middleware and services to enable seamless and instant collaboration among knowledge workers in group forming networks, beyond organisational boundaries. iv) The creation of new tools that simplify the complexity of collaboration in dynamic work environments and which enable users for creative and knowledge intensive tasks. ECOSPACE is deploying a systemic approach built on matrix based organisation with horizontal technology push activities and vertical application pull activities. Vertical validating applications apply a Living Lab approach within 4 application areas. They act as breeding grounds for innovation; they prepare the broad acceptance of the results, and create open business opportunities for new generic or sector-specific products and services.
