Despite the long bibliography sure there are many related publications that I missed during my research. This issue collects the most important gaps.
Charles Petzold (1999): Code: The Hidden Language of Computer Hardware and Software (recommended by Jeff Atwood. The book seems to be no scientific research but a good introduction)
Michael Blaha (2010): Patterns of Data Modeling. (somehow I missed this book. seems to be similar to the books by Hay and by Silverston).
Hui, Yuk (2012): What is a Digital Object? In: Metaphilosophy, (43), 380-395 (or his PhD on the same subject - I discovered his work just after finishing my PhD)
