History and current status

• Goobi was developed as workflow tool for the federated digitization project RusDML.– During this project it was used in a distributed model: Scanning took

place in Goettingen, metadata was gathered in Berlin and Moscow.

• It’s used under production conditions by the GDZ since 2006.

• SUB Goettingen and SLUB Dresden got an 18 month grant from the German Research Foundation (DFG) for further development.

• We are currently working on release 1.5. The main Goal for 1.5 is to be able to produce a software that is capable to fulfil the recommendations of the German Science Foundation (DFG) regarding digitization projects.
