With the help of unified interfaces, individual systems' particularities can be hidden, thereby facilitating the exchange of data between heterogeneous applications. However, existing concepts mainly concentrate on technological issues and must be extended toward the semantic level to ensure that different applications have the same understanding of the business meaning of services. We propose a novel composite of several methodologies issued by the UN/CEFACT that bridges the semantic gap existing in current SOA deployments by introducing a loose coupling between the meaning of business data and its representation. This standards composite builds upon an evolutionary and collaborative approach and supports the modeling of both commonly comprehensible business documents and collaboration processes.enSOAUSOAUN/CEFACTEnterprise InteroperabilityClosing the Semantic Gap of SOAEnterprise Application Interoperabilityconference paper
