Digital Financial Reporting

I have written a simple software application in Microsoft Access that extracts the XBRL calculation relations (i.e. roll ups) of 5,734 10-K financial reports submitted to the SEC.  You can download the database and other tools if you want to analyze the roll up relations:

• Here is the database: This contains 807,924 roll up relations from the 5,734 reports.  It also has a list of the reporting entities.  The database also has the extraction code which should work if you have a Microsoft Access license.
• Documentation: This documentation helps you understand how to use the database.
• Excel extraction tool:  The database has ALL 5,734 reports.  This Excel tool can be used to extract XBRL calculation relations from one report at a time.  It can be modified to do more.

If you make any interesting modifications to the tools or discover any interesting patterns in the information, please be sure to let me know.
