Great stuff from Tom Bruce testifying before Congress.
"Such a point-in-time system -- one that makes it possible to know what the state of the law was at a particular time in the past, or what it will be at some point in the future when pending laws come into effect -- would be a very valuable tool".
Indeed. I would go further however. Without such a system you do not have a comprehensive audit trail that explains how your laws came to say what they do. Nobody would accept a P+L and a Balance Sheet without detailed transactions to back it up. Why do we accept it for something as critically important as law?
It is nice to see many of the concepts that underpin the LWB architecture coming more into main stream thinking about legislative IT.
