XBRL-based structured digital financial reporting - Blog: Digital Financial Reporting (using XBRL)

Periodically I take a look at SEC XBRL financial filings in order to better understand those filings. I have a number of resources which I use. The filings which I am analyzing are 10-K, 10-K/A, 10-Q, and 10-Q/A filings made between November 1, 2011 and February 29, 2012 per the SEC RSS feed archive. The total number of filings which I obtained was 4416.

Here are some of these resources which you might find helpful in order to explore and better understand SEC XBRLfinancial filings:

Excel spreadsheet with all 4416 filings. Basic Excel spreadsheet with all the filings, information relating to core financial report semantics, and other information.
Excel-based taxonomy explorer. Excel spreadsheet with macros which allows you to load filer taxonomy into an Excel spreadsheet, view the taxonomy within a tree view control, explore various lists of filers (prototype).
HTML flat list of filings. Flat list of filings, links to the filing on the SEC web site and to the filer taxonomy rendered as a flat HTML web page.
Viewer format. A table of contents which goes down the page, you can view either the SEC interactive data view or the filer taxonomy as a flat HTML page.
Computer readable XML file (RDF format). Computer readable XML file which can be used to read the filings, the relations infosets which contains taxonomy information.
