Exploring collaborative digital heritage communities: A quantitative assessment of Wiki Loves Monuments in Italy

The debate on the digital transition of cultural heritage has often focused on the op-portunities , challenges faced by cultural institutions, but in recent years a growing at-tention has been devoted to understanding the role of grassroots and collaborative initia-tives in contributing to this process. In this article, we study the Wiki Loves Monuments (WLM) contest in Italy, one of the largest and most widespread collaborative projects con-tributing in documenting cultural heritage through open access tools. Using quantitative and qualitative evidence collected from ten editions of the initiative, the paper investigates the contribution of collaborative digital communities in the production and sharing of knowledge about cultural heritage on the Internet. In particular, our findings point out to systematic differences in the rate of documenting monuments across regions , types of municipalities, as well as peculiar patterns of the WLM community in the modes of con-tribution and re-use of images in Wikimedia projects. The analysis adds insights into the opportunities and challenges that collaborative projects through open access and re-use of digital content can offer for the enhancement of cultural heritage.
