The purpose of the investigation project described here was to develop an intangible heritage inventorying methodology suitable for Portugal and in accordance with the provisions of the UNESCO 2003 Convention, the Operational Directives and the recommendations of experts. Within the project, the inventorying methodology and the instruments developed were tested on a sample of people involved with specific elements of ICH from the five Convention domains, and with an ICH element from the domain of traditional craftwork – the production of inlaid ceramics in Nisa, a small Portuguese village in North Alentejo.
