Data Modeling in Gallia

This documents present the data model expected for manipulation with Gallia. WIP

Relates to json.md

Guidelines

• No empty objects (use Option if may be missing)
• No empty arrays (see next point)
• Only one way to express null/missing; consider forbidding even empty string [res]?
• No 2D (or more) arrays, use dedicated tensor objects if needed
• Types:
  • TODO: add types (See BasicType.scala)
  • Flags: use optional boolean + one value for now
  • Binary data: use _Binary (introduced in 0.4.0)
• Keys:
  • Keys for a given object level must be distinct
  • Keep keys simple: alphanumerical + underscore
  • Keys to convey semantics as much as possible (relates to semantics task
  • No "maps", favor including key in an object, so schemas can be defined against data; basically keys should not be arbitrary
