What it actually is
ODS documents older Danish with full citations, which is what you need once you start reading Blicher, Pontoppidan or anything printed before the war and hit words DDO no longer carries. Purely a reference for advanced readers and anyone curious about how the language moved. Entries are written in older Danish themselves, so it is unusable below a solid C1.
