Towards a Complete Metamodel for DEMO CM

The Design and Engineering Method for Organisations (DEMO) is the principal methodology in Enterprise Engineering (EE). The Design and Engineering Method for Organisations Specification Language (DEMOSL) states the rules, legends, and metamodel of DEMO. Therefore, any DEMO model must comply with this specification. Moreover, to enable automation of the DEMO model validation, we need a metamodel that can accurately represent DEMO models. In our research we are expanding the DEMOSL to be able to express all DEMO models and rules. This paper reports on the attempt to build this metamodel for four elements of the Construction Model (CM) using mathematical and semantic notation. The findings on the validation done on DEMOSL have been added to the build metamodel. We found the notations to be sufficient to describe and validate the DEMO (CM) models.
