This Olfactory wiki-thon is part of the Open Sourcing Smell Culture weekend. It is a year-long collaborative program between the Institute for Art and Olfaction, Pochpac and Mediamatic that explores alternative attribution and sharing strategies for the perfume industry. The program will take the shape of workshops and working groups, and will culminate in 2019 with the publication of a set of recommendations for open source methodologies in scent creation, perfumery, and related practices.
