This paper presents the use of the “Jibiki” generic dictionary online development platform in the case of the GDEF Estonian-French bilingual dictionary building project. This platform has been developed mainly by Mathieu Mangeot and Gilles Sérasset based on their research work in the domain. The platform is generic and thus can be used in (almost) any kind of dictionary development project from simple monolingual lexicons to complex multilingual pivot dictionaries as well as terminological resources. The platform is available online, thus it allows entry writers to work and collaborate from any part of the world. It consists in two main modules and data management tools. There is one module for elaborating complex queries on the data and one module for editing entries online. The editing modules generate automatically an interface from the XML structure of the entry.
