# 5.1 Overview

This section describes Kanon and its technical underpinning in Primitive Indexing.

Primitive Indexing converts the crowdsourced ontologies into ***ontology primitives*** called **Kanon** (See Section 5.7. for more details). This process requires the following moving parts:

* *Synesis Metaverse* – the mental map of digital human knowledge
* *Synesis Relevance Index* – the list of the most frequently accessed ontology primitives
* *Synesis Relevance Index Score* – the measure of ontology primitives (Kanon) usage
* *Kanon Exchange* – the NFT data marketplace for Kanon
