Are we using colon as a separator for fqn? For gcp resources it is something like "projects/{project}/...", will the DC integration replace colon with expected character? How will it know when to replace it?

[avirmani]

is there a way to find out if thats the case anywhere?

They start with pluginName followed by ":". For example GCS is gs://{bucket name}{path} and BQ is bigquery:myProject.myDataset.myTable.

is it possible to add a new field for FQN rather than use the dataset id? This would be safer, but I'm not sure if it would allow us to meet all the requirements for this project.

@snehalakshmisha do you think we can do this?
