The 2009 version of the US GAAP XBRL Taxonomy was released by XBRL US about a week ago. That page has information helpful in the general use of the taxonomy:
- Home page of the taxonomy: http://xbrl.us/Pages/US-GAAP.aspx
- Viewing the taxonomy (the CI entry point which most companies will use): http://viewer.xbrl.us/yeti/resources/yeti-gwt/Yeti.jsp#tax~(id~6*v~31)!net~(a~78*l~25)!lang~(code~en-us)
- Preparer's guide: http://xbrl.us/Documents/PreparersGuide.pdf
For some reason, a pointer to the web version of the taxonomy (such as this for the PRIOR TAXONOMY http://xbrl.us/us-gaap/1.0/ WHICH POINTS TO THE PRIOR TAXONOMY or this one which points to the IFRS taxonomy http://xbrl.iasb.org/taxonomy/2009-04-01/) is NOT being made available.
Eventually, I am going to build some extension taxonomies which make working with the US GAAP Taxonomy easier. Not sure when I will get around to it.
