Add Structural Metadata

[rodericcomyn]

dataClasses (array)

• label (string)
• description (string)

dataElements (array)

• label (string)
• description (string)
• dataType (string / enum?)
• sensitive (bool)

1. Suggest adding an optional count for each array
2. Suggest using name instead of label
3. Suggest using lowercase datatype as a string enum. Do we want the possibility of users to suggest their own data types and/or format constraints?
4. Do we want to have a word limit of decription?
5. Do we want to capture logicalName? e.g. eid may be the field name, but logically may represent "Event IDorEthnicity`
6. Do we want to keep them separate from the core schema? If separate at what point do major changes affect the core schema. Not a loaded question.
7. Do we want to capture lookup or data dictionary tables that may be open access?
8. Do we want to combine the profile elements as optional attributes or keep them separate to the structural metadata

It would be good to survey the standard landscape of that is used for such profiling data and either reuse them or extend them.
