On 21 February 2020, meemoo, Wikimedia Belgium and the Royal Library of Belgium organised a special study day in Brussels in celebration of Public Domain Day. Pascal Ennaert (Vlaamse Kunstcollectie) introduced the activities of VKC as a service organisation supporting Flemish museums with image and data management, focussing on three layers: the content layer, exchange layer and reuse layer. He also introduced some important steps in managing and sharing data and images, a.o. the ‘information policy plan’, standardisation and enrichment of metadata, and a layered licensing model. However, opening up digital heritage collections is not only a technical challenge. With regard to Public Domain Day's theme, Pascal Ennaert pointed out the legal challenges he encountered while gathering digital surrogates from various heritage institutions around the world for their online exhibitions on the oeuvre of James Ensor and Pieter Bruegel the Elder, both of which are in the public domain. While gathering them from a collection of international heritage institutions, Ennaert was confronted with a whole spectrum of inconsistent rights statement practices ranging from unclear, contradictory to plain wrong. With this overview, he made it clear that copyright remains sometimes poorly understood and applied by heritage institutions and that the need for revenue-generation is making it hard for institutions to open up their digital collections in a way which is consistent with their legal status. Placed in a broader context, many Belgian museums aren’t doing so badly with regard to rights statement practices. The presentation ended with some examples of good practices in using works in the public domain.
