If the schemas provided in the HERE platform do not describe your data or support your use case adequately, you can create your own schema. To create a schema you must use one of the HERE platform SDKs. To access the SDK from the platform portal, click the Resources tab then click Download the SDK.
You must have the HERE Workspace plan to have access to the HERE platform SDK.
Use the SDK to create a schema and deploy it to the HERE platform artifact repository. For more information, see Create and Extend Schemas.
The schema should now be visible in the list of schemas available in the HERE platform portal. The schema also appears in a dropdown list of schemas when configuring a data layer.
Schemas are only visible to the user who created it. To share a schema with other users, see Share a Schema.
