Open data initiatives from governments or local authorities are recent, but they have rapidly resulted in the development of services or mobiles applications, often dedicated to tourism. This paper defines the open data phenomenon and explores the different implications for the tourism industry, considered as a sectoral system of innovation and production. This approach allows to grasp the different dimensions of the impacts of open data - institutions, knowledge bases and technologies, organizations and interactions, demand - their co-evolutions and resulting evolutions of the boundaries and dynamics of the tourism industry.
