Configuring the Hub
The Hub provides a set of objects (views, facets, search screen, dashboard and so on) that support the metadata configuration of your tenant.
A collection of JSON files is used to define the Hub configuration and those are accessible only by Reltio personnel. But it is important to understand the Hub configuration concepts and how they relate to the Reltio platform's Information Model and the metadata configuration as discussed in this video.
Some aspects of the UI can be performed using the UI Modeler found within Reltio Console. See "Reltio Console" for more details.
