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 diferent 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. Keywords ontology, agriculture, semantic resource, knowledge representation, crop itinerary 1. Introduction Agricultural production practices are changing and crop production are facing multiple vul- nerabilities: economic, regulatory, environmental and social (isolation, skills, overload, etc.). Moreover, the pressure created by distribution chains and the consumers’ demand for better and healthier vegetables, produced in local area, force farmers to improve crop management. Several scientifc studies [1, 2] have shown diversity –-both in time and space– of cultivated plants: • improves risks management with respect to weather and economic changing context; • delivers a natural defence system against diseases and pest attacks; • increases stability and resilience of agro-ecosystems.
