Transformations

Handle fact transformations.

What are fact transformation rules? In iXBRL filers are allowed to tag textual values like "one million" or "17th of January 2022". In XBRL those facts would be represented in a normalized manner (1000000, 2022-01-17). To normalize the text values, the iXBRL specification provides for so-called transformation rules. The transformation rule "zerodash" for example tells us that the tagged char "-" has a normalized value of 0.

The transformation rules are collected in a so-called transformation rule registry. As of writing SEC Edgar supports the following registries:
