Extend that schema with the option to either provide a single Project or an array of Projects

[pbrenton]

This should not be a part of the project schema (PMM) itself, but it should be part of the 'wrapper' model surrounding the 3 sub-models.

I have included this concept in my JSON schema representation in the form of the object named 'programOrCampaign' which contains an array of projects as follows:

a 'programOrCampaign' contains an array of 'projects'

• a 'project' contains:
• • an array of pmmCoreTerms; and
• • an array of pmmExtensionTerms; and (optionally)
• • an 'activitySet'
• an 'activitySet' contains:
• • a 'datasetMetadataSchema' which contains
• • • an array of 'dmmCoreTerms'; and
• • • an array of 'dmmExtensionTerms'
• • a set of 'observationalData'
