This deliverable comprises three Case Studies describing the preparation of 3D content by partners in the CARARE Project for provision to Europeana and its end-users. The deliverable is presented as a portfolio of documents comprising of this executive summary, the three case studies and four examples of 3D-PDFs. This approach allows each Case Study to be published separately on the CARARE project website in an easily readable format for members of the best practice network. Each Case Study consists of: An abstract and keywords A short introduction Description of the collections Description of the process Mapping Conclusions Acknowledgements References The Case Studies describe the content of the 3D models, the processes used and the challenges faced by each organisation in creating 3D documents suitable for online publication from the original 3D formats. All of the Case Studies make use of the extensive work carried out in Work Package 5 which has been documented in two principle public deliverables: D5.1 Functional specification of requirements for preparing 3D/VR for Europeana - Daniel Pletinckx (Visual Dimension bvba) and David Haskiya (EDLF) D5.4 3D/VR Training materials - Daniel Pletinckx (Visual Dimension bvba) and Paola Ronzino (STARC).
