A review of digital object architecture and handle system: Development, current applications and prospective

With the continuously growing of data, humanity has engaged in a digital age. The importance of data is accentuated, and the future world will presumably be a world of digital objects. That circumstance makes people start thinking of a means to manage and identify efficiently all those data. The digital object architecture (DOA) is a comprehensive architecture for managing digital objects with a persistent identifier assigned by the Handle system. They are more and more applied in several sectors to manage data. Their utilization faces some limitations. This paper will provide a brief overview and explore their real-world application. We will also analyze those architectures’ challenges and suggest ideas for future research to overcome those challenges. To the best of our knowledge, this will be the first review that elucidates the Digital Object Architecture and Handle System. The analysis reveals that most of the research focused on three areas: the IoT (Internet of Things) and IIoT (Industrial Internet of Things), educational domain and research, and multimedia content. There are also a few papers on the application in other sectors like logistics and supply chain, authorization, and authentication systems. The study also shows recent interest in the association of DOA and, handle systems with blockchain
