Define minimum required properties

[jlblcc]

We need to define the minimum required properties for a valid ADIwg mdJSON file.

Note: ADIwg required/recommended/optional fields are a separate issue (although I imagine ADIwg required will equate to the schema minimums).

Currently, the json-schema requires:

• schema{ } > version{ }
• schema{ } > contact[1]
• schema{ } > metadata{ } > resourceInfo{ }
  • schema{ } > metadata{ } > resourceInfo{ } > citation{ }
  • schema{ } > metadata{ } > resourceInfo{ } > abstract
  • schema{ } > metadata{ } > resourceInfo{ } > status
  • schema{ } > metadata{ } > resourceInfo{ } > language[ ]
  • schema{ } > metadata{ } > resourceInfo{ } > pointOfContact[1]

[jlblcc]

We should review this.
