Crop planning and production process ontology (C3P0) is a representation of agricultural knowledge for diversified crop production. It is composed of eight modules to take into account all the elements involved in crop production as well as the complexity for representing farming practices and constraints. Especially, the crop management module is sliced in three different layers to capture the generic information about crop itineraries, the planned production process and the tasks eventually really achieved been by various agents in the plots. To implement this ontology, we designed a new pipeline, presented here, integrating various existing tools to ease the ontology documentation, population and maintenance tasks.
