ROOT (Entity Definition)

ROOT is an essential attribute type in the EAV model that defines core characteristics without which an entity loses its fundamental meaning.

Examples include hotel star rating, hormone type, and company address. In content structure, ROOT attributes go into the main H2 sections after UNIQUE attributes.

In competitive gap analysis, ROOT attributes appearing frequently across competitors are mandatory for complete coverage. Their absence signals a critical content gap with high priority. ROOT attributes build the core of Topical Coverage and go into the CORE section of the Topical Map.
