A sharing platform is a digital platform that facilitates access to underutilized goods by renting or lending them to others. Users become less dependent on ownership which improves efficiency, sustainability, and the sense of community. The Sharing Economy (SE) is considered a complex domain because value co-creation can occur between multiple types of platform users. Developing platform software that offers the right functionality for the intended digital platform is therefore challenging. To address this complexity, an ontology can be utilized, which is an explicit specification of a conceptualization that provides a controlled vocabulary and shared meaning regarding a domain. The use of a sharing platform ontology allows for more effective communication and knowledge sharing amongst stakeholders in platform development and eventually drives the platform software development process. However, currently, it is not known how to develop such an ontology. In previous research, we developed the Digital Platform Ontology (DPO) and an extension of the DPO for describing platform business model choices. The DPO describes the digital platform domain in terms of digital platform types, including sharing platforms. However, a method to use the DPO and its business model extension for developing an organization-specific ontology that describes the functionality and business model of a specific existing or intended sharing platform was lacking. In this paper, we develop such a method using the Design Science Research Methodology (DSRM) and demonstrate it using a proof-of-concept based on the BlaBlaCar and Couchsurfing platforms.

Digital Transformations (DT) play an increasingly important role in academia and business, yet their significant Environmental Footprint (EF) is often overlooked, sidelining their potential for Environmental Sustainability (ES). This paper bridges this gap by integrating ES into the discourse of DT, proposing Green Enterprise Architecture (GREAN) as a method for sustainable transformation. Utilizing a Design Science Research approach, we developed an artefact outlining a comprehensive strategy for embedding ES in DT across various layers of an organization. The tool’s need was validated via a systematic literature review (SLR), highlighting the significant research gap in Green Enterprise Architecture. The artefact provides concrete Courses of Action (CoAs) for incorporating ES into the organizational strategy, business, data, application, and technology layers and proposes relevant capabilities to address this. The paper further presents an ES-aware business capability modelling, an innovative business modelling approach that integrates environmental sustainability principles by using (in a novel way) the presentation and analysis methods that capability mapping offers. The proposed artefact serves as a starting point for environmentally sustainable DTs. Future research directions include in-depth exploration of each enterprise layer for ES, real-world validation of our proposed tools and concepts, and the expansion of these into a full framework.

Process maps provide a high-level overview of an organization?s business processes. While used for many years in different shapes and forms, there is little shared understanding of the concept and its relationship to business process architecture. In this paper, we position the concept of process map within the domain of architecture description. By ?architecting? the concept of business process map, we identify and clarify diverging views of this concept as found in the literature and set requirements for describing process maps. A meta-model for a process mapping language is produced as a result. The proposed meta-model allows investigating the suitability of EA modelling languages as a basis for defining a domain-specific language for process mapping along with the creation of a better understanding of business process architecture in relation to enterprise architecture, which can be beneficial for both BPM and EA professionals.
