If no numeric relations exist, then the information model of the component is a hierarchy. Basically, anything can be modelled as a hierarchy. It is the addition of additional relations, typically computations, which turns a hierarchy into some other metapattern.

This information model is commonly referred to a 'roll up', or the equation A + B = C. All concepts involved in this information model have the same set of characteristics and all must be numeric.

This information model is commonly referred to a 'roll forward' or 'movement analysis' or the equation: beginning balance + changes = ending balance. In this equation period [Axis] is as of two different points in time and the changes occur during the period between those two points in time.

For example, the salary information for the directors of an entity is a compound fact. The salary information is made up of salary, bonuses, director fees which roll up into total salary and this set of compound facts can be expressed for any number of directors, the director being the characteristic or axis of the compound fact.

An adjustment is similar to a roll forward in that it is a reconciliation, however rather than the period [Axis] changing; it is the Report Date [Axis] which changes: originally reported balance + adjustment = restated balance.

For example, a sales analysis which reconciles the concept sales for the reporting scenarios of actual and budgeted is a variance. The equation is: actual - budget = variance.

The type of computations can vary significantly, thus the challenging in modelling. For example, the computation of earnings per share is a complex computation.

For example, the narrative associated with a set of accounting policies expressed as a list or a table presentation format is a text block. As there is only one concept, there can be no relations within the information model. Mon, 4 Jul 2011 11:44:03 GMT http://www.xbrlsite.com/DigitalFinancialReporting/Metapatterns/2013-05-15/08-TextBlock/TextBlock-SampleInstance.xml http://www.xbrlsite.com/DigitalFinancialReporting/Metapatterns/2013-05-15/09-Grid/Grid-SampleInstance.xml A grid information model is a pseudo metapattern which uses the presentation characteristics of the columns and rows of a table to model information. Because the grid models presentation information and not business semantics, it cannot be considered a metapattern. However, the grid is included in this list because the US GAAP Taxonomy uses a grid information model to model the statement of changes in equity.
