The “OpenAgri Digital Farm Calendar” service aims to address the data capture needs of farms by providing for the manual recording of: farmers activities, farmers observations, parcels properties and the recording of the farm’s assets. A Web User Interface (UI) is provided which allows the users to visualize and navigate through the farm calendar of activities and to facilitate the management of the farm assets. In addition, all these operations and farm assets can be managed through a REST API, which provides these resources in a linked data format (i.e., using JSON-LD) and conforms to the OpenAgri Common Semantic Model (OCSM).
