- Conceptual modelling is often argued to be a core technique in information systems development. An important aspect of conceptual modelling is the ontological and philosophical questions of how to conceive of object existence and identity. Despite significant interest in the topic, formal agreement on how object identity should be represented in modelling languages remains an open question. In the literature, the predominant view is that an object, or entity, is a modelling construct used to represent things. Contrary to this view, we draw on theories of language use and social ontology to understand object identity based on the notion that identity cannot be limited to the identity of physical things. The emphasis is on how language is used to create conceptual entities in a way that maintains fidelity to physical reality and ensures reliable identification of entities across domains. The theoretical implications of this work are primarily the new perspective of conceptual modelling that social ontology affords and the formal introduction and ontological grounding of institutional entities, which have so far been treated rather incidentally. Practical implications include a better foundation for designing and selecting identifiers and classes.

Software Modelling Languages : A Wish List

- Contemporary software engineering modelling tends to rely on general-purpose languages, such as the Unified Modeling Language. However, such languages are practice-based and seldom underpinned with a solid theory – be it mathematical, ontological or concomitant with language use. The future of software modelling deserves research to evaluate whether a language base that is compatible with these various elements as well as being philosophically coherent offers practical advantages to software developers.

Modularization constructs in method engineering : towards common ground?
- 2007

Konferensbidrag (refereegranskat)abstract
- Although the Method Engineering (ME) research community has reached considerable maturity, it has not yet been able to agree on the granularity and definition of the configurable parts of methods. This state of affairs is causing unnecessary confusion, especially with an ever increasing number of people contributing to ME research. There are several competing notions around, most significantly ‘method fragments’ and ‘method chunks’, but also ‘method components’ and ‘process components’ are used in some quarters and have also been widely published. Sometimes these terms are used interchangeably, but there appears to be important semantic and pragmatic differences. If the differences are unimportant, we should be able to come to an agreement on what construct to promote. Alternatively, the different constructs may serve different purposes and there is a need for them to coexist. If this is the case, it should be possible to pinpoint exactly how they are related and which are useful in what contexts. This panel is a step towards finding common ground in this area, which arguably is at the very core of ME.
