Is your feature request related to a problem? Please describe.
Currently the API revisions and changes (of the structure and the data) don't maintain well such as not to be disrupted with major feature change.

Describe the solution you'd like
To provide a more robust API language and data structure for later processing and presentation (visualisation or otherwise), we should provide the data in a node/graph network structure.

Also our FieldTables may offer themselves better to a Graph Database.

Describe alternatives you've considered
A good start would be https://graphql.org/ before moving to a graph DB for even better query abilities on large survey data.
