: Documenting and maintaining an enterprise-wide service-oriented architecture (SOA) causes a substantial management effort which should be addressed by intelligent, scalable solutions. A particular challenge is that business experts, developers and software architects take different perspectives on a SOA, which leads towards a scattering of architectural information throughout various formats and sources. Ontobrowse Semantic Wiki specifically addresses these issues by providing an ontology-based integration and documentation platform for architectural information. In this paper, we first identify the main issues arising from documentation and maintenance by introducing the case of an enterprise SOA in an insurance company. Then we give a detailed description of the Ontobrowse approach and its implementation. At last, we explain how ontologies, artifact mappings and architectural rules are created to support the Enterprise SOA case.
