This paper presents the design and development of a Cloud-based Digital Gallery Solution, for gallery administrators to manage and demonstrate rich exhibition information to visitors. Our solution consists of client side and server side. Both sides are discussed with their features and key components. Specifically, the iPad app is developed on the client side for gallery visitors. On the server side, exhibition data is stored and maintained on Dropbox, and Restful services are used for data retrieval. Besides, model-view-controller design pattern is adopted in the mobile app development for efficiency. Our system provides gallery administers a convenient tool to present rich exhibition information to visitors in a friendly way. Currently, this solution has been employed in John Ben Shepperd Public Leadership Institute at Odessa, TX.
