Abstract. Traditional industries anticipate supporting cross-organizational cooperation as applied in the semantic Web and Web services environments. However, the international standards used in organisations are often developed prior to or independent from the novel technologies. We demonstrate a solution, namely to perform controlled semantic transformations enabling both technologies. A study in the semantic relationship between an international standard, ISO 15926 Part 2, and a semantic Web technology, OWL DL is reported. Three alternative semantic transformation approaches are identified where two are further elaborated. Accordingly, two Transformation Protocols are developed in order to transform ISO 15926 components to OWL. Further, two Inverse Transformation Protocols are developed. The transformations are analysed and the alternative transformation protocols are evaluated.
