The democratisation of the question of heritage, its integration into sustainable development projects, as well as the involvement of new participants, notably social ones, in the valuing and interpretation of local cultural heritage allows the emergence today of community-based expressions of heritage embedded within cultural diversity. Therefore local organisations become key players in this process of ‘heritagisation’ of cultural inheritance. Our proposal will be focused on Ksar Ait Ben Haddou, inscribed as World Heritage in 1987, and more specifically on the project for the oral tradition house carried out by the Ait Aissa Association for culture and development (http://www.associationaitaissa.com). The objective of this project, which lies at the heart of a global project for the development of this site, is to document and interpret the expression of intangible heritage of Ksar through combining fieldwork amongst the local population and their representatives with digital techniques for documentation and interpretation of this heritage. The fieldwork will be undertaken using ethnographic methods which will allow the collection of data which will enable documentation of still living expressions which make sense for the community. Digital techniques will be used in two ways: firstly in the documentation and archiving of selected expressions, and secondly in the living interpretation of this heritage.
