In an annual report the financial health of a company is presented as either text or numeric values.
· Numeric Presentation: In business reporting, there are certain data points which are best reported if quanitified hence numerical values are used to report this. These can be best depicted using tables.
The data represented under single data head could be explained using simple hierarchy. Eg Total Profit present in balance sheet etc. However, for certain data points, it is necessary to use more than 1 data head to make sense out of it. For eg:
For such data representation, a complex hierarchical structure is needed wherein 2 data heads are to be understood to interpret the data reported. Eg. In notes where the key financial concepts like revenue, assets are categorized for different geographies/products etc. Certain type of repetitive disclosure like details of all subsidiaries, directors etc. also fall in this category.
The Repetitive Tabular Data
Let us take an example of reporting for details of directors of the company. Now, not only the number of Directors for Company A will be different from number of Directors for Company B, but also the information about a Director is best understood by looking at related data like Director’s Name, Education, Experience, Skill set etc.
While designing an XBRL taxonomy to cater to such requirements, it is necessary to select a data model which can allow caputring of multiple occurances and also is generic. One of the alternatives available to handle the above scenario of reporting multiple occurrences of grouped data is through use of ‘Tuples’. In this example, ‘Name’ , ‘Qualification’ etc. elements will be present in the tuple. The preparer can use these to tag specific data sets for their reporting.
· Textual Presentation: However, sometimes the information can’t be quantified, hence free-flow text is needed to make sense out of data. These are large chunk of texts used to report the health of a company, usually termed as Nota Integrativa.

Tuples: A global phenomenon
XBRL Global Ledger (GL) taxonomy extensively uses Tuples. The GL taxonomy is designed to capture the transaction details which would then roll-up to any report. Since the very nature of transactions makes the record unpredictable, Tuples fit best in this scenario.
To conclude I can say that when it comes to dynamic records in XBRL taxonomy, Tuples is a great tool to serve the purpose.
