In the last 15 years, the creative scene in Douala (Cameroon) has been documented on Wikipedia – the widest online collaborative encyclopaedia – which has largely contributed to give access to the cultural richness of the city through articles, images and multimedia files and data. This article focuses specifically on Wikipedia content about contemporary public art in Douala produced in the frame of the project “Culture and Safety in Africa”[1] (2015-2018). The project aimed at improving and correcting the limited and biased information about African countries, with a specific emphasis on their local artistic and cultural practices. At the end of January 2018, the project produced and improved a total of 95 articles on Wikipedia in English (n. 46) and French (n. 49), 118 images uploaded on Wikimedia Commons, 24 entries on Wikidata and 3 new categories. Content was specifically related to: · Public artworks in Douala; · African and international contemporary artists working on urban practices in African cities; · Meaningful terminology needed to comprehend the African contemporary art scene; · Bibliographic references related to African cities; · Portraits of artists, and pictures related to their artworks and cultural events in Douala. This analysis focuses on the articles created and improved by the research and it quantitatively assesses their impact after three years from their first publication or update. Outcomes of the evaluation allows to observe: · a significant growth in the visualization of the articles by the community of readers demonstrating an increased interest in relation to topics covered by the project; · an increase in the number of changes to each article and the number of editors involved, showing the collaborative nature of Wikipedia; · an increased number of articles whose quality has been assessed independently by the Wikipedia community - according to Wikipedia article quality grading scheme - showing a higher engagement by the Wikipedia Community on the content produced. This article argues that Wikipedia can be a powerful tool to increase knowledge and visibility of African cultural heritage. The assessment of the documentation of public art produced on Wikipedia shed light on its potentialities in decolonizing cultural heritage, widening the accessibility of local production, and fostering international collaboration.
