Why Consider a Dimension Only Approach For XBRL GL – Part 2 –

Views: 113

Goal

The current XBRL GL uses the element and the SRCD module (The Summary Reporting Contextual Data (SRCD) module) to define correspondences in order to aggregate detailed data into FR. In order to interpret this definition, it had to be processed by special software.
It was verified that even in XBRL GL defined by the taxonomy of XBRL in a format that does not use tuples, it is possible to define the correspondence with FR using the formula link base of XBRL and aggregate detailed data.

XBRL GL and SRCD formula linkbase with typed dimensions

Conversion source XBRL GL taxonomy (glTaxsonomy.xsd)

Conversion source XBRL GL instance (glTargetInstance.xml)

Conversion destination FR taxonomy (FRTaxonomy.xsd)


Formula linkbase definition for conversion
