Our database Edgar Online I-Metrix now has a tab "File in XBRL." If you click on it, the link goes to information from Edgar Online, including "Learn about XBRL."
As Louise reported last week, the SEC voted last week to issue a proposed rule, that if finalized this fall, will mean that SEC filings using XBRL will be phased in over the next three years. If the rule is finalized, the phase in will start in December 2008.
I watched a free information/training session via the web sponsored by XBRL-US today. When the slides and other information are emailed, I will share them with everyone.
