Introduction 1.1. Digital Platform Eco-system The concept of a digital platform is described in order to comprehend the digital platform eco-system. According to [7], a platform can be utilized as a foundation for the development of supplementary products, technologies, or services. A digital platform empowers the customer and producer to trade value through information technology [2], [7]. Depending on the number of participating roles, such as producer and consumer, these digital platforms are referred to Abstract: Due to the numerous components in various domains that need to be identified in digital ecosystems, the design of digital platforms spans a variety of areas that complicate the development process. Misalignment between the various domains, such as business-IT, may result from the intricacy and decisions made. We found that the primary cause of the complexity is the ignorance of those who develop digital platforms. In order to convey knowledge about the motivation, business, application, and data domains, we developed a reference model. We developed Enterprise Architecture (EA) patterns in each area using the ArchiMate language after identifying pertinent digital platform principles with the help of literature. These trends outline the decisions that must be made while developing a digital platform for service exchange. We also concentrate on the application domain on how business and IT are in sync. We developed a visualization tool that allows natural language to generate perspectives using the reference model in order to get around the problem of ArchiMate's lack of popularity. In order to verify the reference model's generalizability, we examined an existing digital platform and conducted a case study at Steel and Tube, a firm that aims to develop a digital platform to offer a casting on- demand service.
