What I'm looking to do, is install a custom Attic (Classical) Greek and Koine (Common) Greek dictionary in OS X to use in the native dictionary app in OS X. In the past, I have installed French and German ones to use within the app. Firstly, I assume, I would have to find an open source dictionary (in an XML file?) to use. However, I don't want to reinvent the wheel if there is something out there. Anyone ever do something similar? Basically, the file I want to install is an xml of Strong's Concordance. It is already widely used on the internet and open source. Simply, I just do not know what folder to put it in nor if I should convert it to a .dict or other filetype.
