I have been playing around with the Firefox XBRL Viewer add on. There are lots of documents one can fiddle with on this RSS feed.
But the most interesting XBRL instance I am seeing is the SEC Model that I created. You can get to that document here: http://xbrl.squarespace.com/storage/secmodel/2010-11-01/abc-20101231.xml.
While the viewer leaves a lot to be desired, it does provide very good clues what working with XBRL will be like some day.
One particularly good feature of this Firefox XBRL Viewer add on is the ability to jump between hypercubes. To try this using the SEC XBRL Model filing:
You can try the same thing for a number of other hypercubes which are connected to each other. That was one of the points of the SEC XBRL Model filing, to point out these sorts of connections.
The fact that you can navigate from one hypercube (referred to as [Table]s in the US GAAP Taxonomy) will help people creating taxonomies to construct better taxonomies (i.e. with these relations properly articulated). It will also help business users grasp the value of XBRL.
Experiment with some of the other XBRL instances in that RSS feed. Each document is there for a reason.
Imagine when:
If you have not fiddled around with the Firefox add on, I would encourage you to do so.
