What is a Rolemap?

A Rolemap in the context of PDF refers to a fundamental concept in Tagged PDF.

It involves mapping various structure types between namespaces, enabling a clear understanding of their intended roles across different PDF processors.

For instance, a custom structure type like "Foo" can be role-mapped to a paragraph in the standard structure namespace, indicating its semantic alignment as a paragraph.

This mechanism supports the effective use of custom structure types within PDF, contributing to the logical structure and tagged aspects of PDF documents (ISO 32000, clauses 14.7 and 14.8).
