Hi, 

Since the relationship have been created between types in the data model. I am wondering why it can’t be made at the backend by CDF but required user to make the relationship transformation manually ? Is it by design ? 

Thanks, 

Kind regards, Carrie

Hello!
It is by design. CDF allows users to create relationships between data elements using the Relationships resource type, as it provides flexibility in modeling data in graph structures that are meaningful for the organization. However, it is up to the user to define the relationships and create the necessary transformations to populate them. This allows for greater customization and control over the data modeling process without making a tangled web of relationships.

You do get some level of “relationship” between resources by having them linked to assets. This allows one to see which timeseries, sequences, files, or events are related to an asset, and this is created when one creates the items in CDF. I would also suggest checking out entity matching as it can help automate this linking.
