"Our current system of galleries, collectors and even public museums is not designed for a commons in art." - Europeana is a EU-funded institution that works towards the "commoning" of artworks, artefacts and cultural heritage at a European level. They provide legal advice and work closely with cultural institutions to make their collections available online. They are probably one of the strongest alliesfor institutions that want to make their collections commons.
Also my PhD research (from University of Copenhagen and Victoria University Wellngton) is on the inscription of commons in artistic practice and I would like to create a reference group as I assemble examples (as well as analyse our own at www.lettingspace.org.nz) - if you would be interested in being part of this reference (with acknowledgment is given to the group) I would be keen to hear from you.
