Open_Data_Description_Language
The Open Data Description Language (OpenDDL) is a generic text-based language that is designed to store arbitrary data in a concise human-readable format. It can be used as a means for easily exchanging information among many programs or simply as a method for storing a program's data in an editable format.
The exact syntax of OpenDDL is described on the website openddl.org as well as in an appendix of the Open Game Engine Exchange Specification.[1]
