Details

Field information can be generated from a data frame by introspecting the data associated with it along with other properties about that column. The data frame is posted to the server endpoint where the data is analyzed and returned as a list of fields each with it's associated list of properties and values. This list can be edited and/or used to create a domain on the server.
