Follow the steps below to create a new interface in Ontology Manager.
First, verify you are working within your Ontology of choice by checking the Ontologies dropdown menu located at the top of the left side panel.
Select Interfaces under the Resources section of the same left panel. From the Interfaces page, select New interface from the top right corner of the screen.
Alternately, you can select the New dropdown menu from the top right corner of the Ontology Manager navigation bar and select Interface.
Any object type that implements the interface must have these shared properties or provide a mapping from a local property to the interface shared property. If a shared property required for the interface does not exist, you must create it.
If you want this interface to link to another interface or object type, you can optionally add any interface link types to the interface.
If an interface link type is required for your modeling use case, any object type that implements the interface must add a new or existing link type that satisfies the interface link type constraints.
