XBRL Formula Specifications - Assertion and Formula Messages

Formula Specification 1.0 - 2009 - 2011 - Recommendation Status

XBRL Formula Messages vs Labels
http://www.xbrl.org/Specification/genericMessages/REC-2011-10-24/genericMessages-REC-2011-10-24.html

Generic labels document XBRL resources, whereas messages are meant to document events, situations or results in a process supported by XBRL.

Generic labels are limited to have only static strings or XTHML fragments. In contrast, messages can include XPath expression in its content in order to calculate, for instance, the deviation of the value of a derived fact from the aspect-matched input fact in a consistency assertion.

XBRL 2.1 - HMRC - requires element

http://www.xbrl.org/Specification/XBRL-RECOMMENDATION-2003-12-31+Corrected-Errata-2008-07-02.htm#_5.2.6.1

There is an arc role in the HMRC taxonomy requiring elements to be reported.

Using the requires-element are role an instance of an concept as a fact requires another to be reported.

Tuple structures can enforce reporting however what about items not involved tuples.

This seems like an existence check


For example, the data that is normally into a paper form could be represented electronically using XBRL instances. To represent the “required field” idea, the taxonomy author can create a definitionArc with the http://www.xbrl.org/2003/arcrole/requires-element arc role value. This arc would link the concepts representing the required fields and an element representing the concept of the form itself.

Edgar filing manual v19 released and fast 2012

Release of the FASB 2012 taxonomy & EFM v19.

EFM manual now versioned for FASB 2012, versioned EFM v19 (v18 has been removed)

http://www.sec.gov/spotlight/xbrl/interactive_data_test_suite.shtml

The interactive test suite still has the EFM v18 test cases, they do not seem to have yet published the
updated tests

This standard taxonomies have been updated, so the

has been updated. .

Will the community make xbrl data better?

Maybe this posting about map data will make us think whether xbrl data is free, and open but if you add value to xbrl then that is the commercial opportunity.

Having the community improve data and contribute sounds like a great idea also
