TAO - Transitioning Applications to Ontologies The goal of the TAO project is to define a low-cost route to transitioning legacy systems to the open semantic Service-Oriented Architectures (SOAs), which will enable semantic interoperability between heterogeneous data resources and distributed applications. IMPACT: This project will offer a low-cost migration path for legacy applications to knowledge technologies and will be accessible to both SMEs (which are cost sensitive) and large enterprises (with huge investments in complex and critical IS). The results will be validated in two high-profile case studies: a comprehensive open source platform (with thousands of users) and a dataintensive business process application (managing a multi-million aviation business).
