Software engineering standards often utilize different underpinning metamodels and ontologies, which sometimes differ between standards. For better adoption by industry, harmonization of these standards by use of a domain ontology has been advocated. In this paper we apply this approach in a proof of concept project. We recommend the creation of a single underpinning abstract domain ontology, created from existing ISO/IEC standards including ISO/IEC 24744 and 24765 and supplemented by any other sources authorized by SC7 as being appropriate and useful. Such an adoption of a single ontology will permit the re-engineering of existing International Standards such as 12207, 15288 and 33061 as refinements from this domain ontology so that these variously focussed standards can all inter-operate.
