We use the XML-editor oXygen for all forthcoming works of Ibn Nubātah. Dr. Christian Lück is adapting it to make it suitable for the edition of Ibn Nubātah's Diwan online, that the other team members work on.
While he was working with ALEA, Prof. Dr. Hakan Özkan published tutorials on how to use oXygen for the edition of Arabic texts. They are available here.
The finished product will be made accessable here.
