This Code of Best Practices aims to help digital heritage curators and creators make informed decisions around the lawful reuse of existing materials in immersive experiences or other experimental products. It is based on the views and statements collected through a series of workshops with creators and curators of immersive experiences from the UK and the Netherlands. While the legal considerations included in this document refer primarily to UK and Dutch copyright law, this Code is written in such a way that it aims to be relevant to other European jurisdictions too.
