In the Middle ages,a farmer had to tie the sheaves of cut wheat (or similar crop) at harvest time in his field. He carried twine to do this. The average length of twine used was approx 13 and 1/2 inches. Hope you find this enlightening. The answer to “How long is a piece of string” is this.

Do you know about WDDX? It was specifically built as a serialize() that is interchangeable between programming languages.
