Dimension Modeling Working Group (DWG)

The Financial Accounting Standard Board (FASB) established the Dimension Modeling Working Group (DWG) to receive input on dimensional modeling and to build consensus for dimensional modeling issues related to the Taxonomy which will result in design principles to inform Taxonomy modeling choices going forward.

TOPICS THAT HAVE BEEN INITIALLY IDENTIFIED FOR DISCUSSION PURPOSES INCLUDE:

  • Appropriately define a concept using primary elements and dimensions
  • Document line item (primary element) versus dimension choices
  • Document appropriate uses of dimensions
  • Defining a decision tree for hierarchical and distinct domains
  • Identify the proper level of abstraction
  • Explore mechanisms to constrain use
