Hello DuĊĦan,
I find this really fascinating. Unfortunately, it looks like the article doesn't explain the proposed format. Where is the domain in the new format? What does "DAY_HOUR" mean? What's the difference between "DAY_HOUR2", "DAY2_HOUR", and "DAY2_HOUR2"? What is the file naming scheme for the new format?
Being fascinated by file formats myself I also wonder. Why not make it binary?
Kind regards Thiemo
