This research report presents an overview of some basic ideas regarding the conceptualisation of a resource description language for business process modelling. This language is an extension to an existing process modelling language — MEMO-OrgML. The basic conceptualisation comprises basic resource types and their mutual relations. It aims to satisfy the needs of different user types and abstractions. The language will be applicable by domain experts and offer domain specific resources and resource types for various domains by offering adequate abstraction on resources. A specialised resource modelling language fosters the reuse of common concepts and assures the integrity of a business process model. The current version of this report has to be regarded as a first draft regarding general concepts of a resource modelling language, requirements and —most of all— open research questions.
