On formal requirements modeling languages: RML revisited

Abstract

Research issues related to requirements modeling are introduced and discussed through a review of the requirements modeling language RML, its peers and its successors from the time it was first proposed at the Sixth International Conference on Software Engineering (ICSE-6) to the present - ten ICSEs later. We note that the central theme of "Capturing More World Knowledge" in the original RML proposal is becoming increasingly important in requirements engineering. The paper highlights key ideas and research issues that have driven RML and its peers, evaluates them retrospectively in the context of experience and more recent developments, and points out significant remaining problems and directions for requirements modeling research.<>
