Abstract

Motivation

Reference models are conceptual models which focus commonalities of organizations, within or across industries and/or application domains (Thomas, 2005) . Reference models hold several promises, like capitalizing on already encoded domain expertise instead of developing a domain model from scratch. As a result, reference models remain a topic of active interest for both practice and academia, as reflected in relatively recent industry reference models like the NISTIR 7628 for smart grid cybersecurity (NIST Smart Grid Cybersecurity Panel, 2010).

However, the creation of reference models comes with several challenges.

As pointed out in de Kinderen & Kaczmarek-Heß (2019) these challenges partly can be traced to the language architecture underlying reference models. In particular these language architectures often do not treat abstraction as a first class citizen. As a result, to model reference models with multiple levels of abstraction, which is typical for industry reference models like the NISTIR 7628, requires (i) workarounds, and (ii) in general comes with a set of inherent limitations which inhibit capitalizing on the full potential of reference modeling.

Objective

The purpose of this master thesis is to make a systematic comparison between conventional meta modeling approaches and multi-level modeling approaches for the purposes of reference modeling. To this end, based upon a motivated selection of a conventional and multi-leveling approach of choice for a well-documented reference model you draw a systematic comparison – specifically as this pertains the specificities of reference models.

As a point of departure, initially the focus will be on NISTIR 7628, which is a well-established reference model for smart grid cybersecurity. However, in discussion with the supervisor, another reference model can also be selected.
