Requirements traceability and change management in multiperspective software artifacts is a major challenge due to the heterogeneity of the artifacts themselves. Our previous attempt in resolving such problem results in a multiperspective requirements traceability framework, namely MUPRET. The key idea of MUPRET is to use ontology, socalled requirements ontology, as a common representation of mutual understanding of semantics of words in the requirements sentences. By doing so, the traceability relationships can be automatically generated when a match is found in the requirements ontologies. Although the MUPRET was originally proposed for the textual requirements, this paper presents the extension of MUPRET to coverdifferent representations of software artifacts, together with an illustrative example of the extended applications.
