Transcript of XBRL GL Data Definition File (DDF) Providing “XBRL GL-Colored Glasses” to Common Text Formats.
Why DDF?
• Helping more people benefit from XBRL GL– XBRL GL is more than an export format– It is a model and framework for describing data– DDF lets us extend the model to non-XBRL information
• Formalizing the description of text files– There are times when describing a text file will help
• Understand the text file• Facilitate the conversion of the text file to XBRL GL• Permit the more standardized transfer of simple text files• Facilitate validation of text files
• V1 Focus: “CSV” (delimited) and Fixed-Length ASCII• V2 - : Binary formats (Excel, Oracle …), XML formats
Scenario 1
• XYZ Company’s ERP system can create delimited files
• XYZ Company wishes to provide the exported file to a third party who can receive XBRL GL
• XYZ Company provides their delimited file plus a DDF file to an intermediary, who can now convert the file to XBRL GL
Scenario 2
• Auditor wishes smallest possible extract from 1 TB company database– CSV = 100 MB– XBRL GL = 400 MB
• Auditor also wants to know what the file represents
• DDF file accompanies CSV, adds negligible size, defines content for automated testing
Scenario 3
• Audit Data Standard– Providing interoperability between• Tab-delimited format, and• XBRL GL
Scenario 4
• A wide variety of software products can turn formatted (“printed to disk”) reports into data– Statistical
• SAS
– Audit• ACL• Caseware
• Generic– Monarch– Altova FlexText
• Why not make it simple to convert information from non-accounting applications?
• Turns non-accounting software into accounting software!
DDF Uses XBRL GL To Define Data in Other Formats
• Information about batch of information• Mappings from text file “fields” to XBRL GL• Mappings from text file content to XBRL GL
enumerations, where appropriate
Delimited vs Fixed Length ASCII
Common: Is there a header row?What format is used for dates?
Delmited (a.k.a CSV):What delimiter is used between facts?What enclosure is used for text, if any?Selection by order
Fixed length ASCII:Is there a fixed record length worth checking?Selection by starting position and length
CSV vs Fixed-Length ASCII1, “Bob”, “Dec. 1, 2099”, “Burled Walnut”, 500
1 2 3 4 5
The number 500 is the fifth item in this record.

The number 500 starts at the 72nd character and is 3 characters long

There is a header rowIt is a delimited file, with the pipe (|) delimeter
The first field is Customer_Account_ID
