Hi and thank you for your interest in templates API!
The main use case for templates is to allow applications and solutions to express their data model as a semantic layer on top of data in Cognite Data Fusion. Often solutions use different concepts than what exists in the source data directly. An example would be a solution for pumps, where the relevant sensors are addressable as properties of the pump objects in the application’s data model created with the templates API. The solution can then query pump data, with properties and belonging data points through a single graphql query.
The templates API is a preview capability, we are eagerly taking feedback and are curious on how we can improve it. Sending you a PM in case you are interested in a follow up.
The documentation, both on the API capabilities and on the guides are, as you have experienced, incomplete.
Best regards,
Jørgen Tennøe
