Zet Universe as Platform is agnostic to data models of its users, enabling customers to define own ontologies and plug them into the default Ontology provided by Zet Universe:
Both developers and end users can extend the default Ontology. Developers can do that by adding and registering definitions of their custom Kinds, Relationships, and Properties as part of their plugins, while end users can use the built-in Ontology Editor (to be provided in the later releases).
As a user, you can switch to Ontology Editor in the main window, to navigate through the hierarchy of the built-in and third-party Kinds, see their respective Properties and Relationships.
