lineage 2.0

[stansmith907]

"resourceLineage" object was renamed from "dataQuality" in mdJson 1.0. The name change fits since dataQuality was separated from lineage in -1 and now is described by ISO 19157. We did not implement any of the ISO 19157 quantitative data quality elements in mdJson 1.0 and as yet have no plans to do so in mdJson 2.0.

Changes:

1. "scope" is a new object ("scope" in ISO) of type MD_Scope. Definition: "type of resource and/or extent to which the lineage information applies." See issue scope 2.0 #100.
2. "citation" is a new array of type CI_Citation ("additionalDocumentation" in ISO). Definition: "EXAMPLE: A publication that describes the whole process to generate this resource."
3. "source" is an array of type LI_Source. Definition: "information about the source data used in creating the data specified by the scope."
   1. *processStep" is an array of type LI_ProcessStep. Definition: "information about events in the life of a resource specified by the scope".
4. At least one "statement", "source", or "processStep" is required for a valid "resourceLineage" record.
