I've red somewhere that the origin of this name is Slavic, of course, and for the first time is shown on the teritory of Czech Republic and Slovakia during 18th century. This name is very popular in all former Yugoslav republics. Meaning: the one that have been given (from God) to his parents. Other script: Дарко (Macedonia, Serbia&Montenegro and Bulgaria)
Darko is not a nickname for Dalibor. Borko or Boro might be nicknames but Darko has a whole different etymology. I don't know how anyone would get Darko from Dalibor.

Feminine version Darka, as part of Božidarka (meaning: the gift from god). Comes from Dorotea (Greek).

The name "Darko" in the name entry is referred as Slovene, Serbian or Croatian. This name is also wide spread in Macedonia and is also considered to be a Macedonian name. There is no reason not to mention this fact. Since this name is spread all over former Yugoslavia (and in this form it exists only in these countries), maybe you could make a reference about this.
