sbJSON: contacts[]>orcId
i. Logic: where contactType = “individual” and “orcId” element exists
ii. contacts block

1. identifier: orcId
2. namespace: “ORCID”
3. version: (not supported)
4. description: “Open Researcher and Contributor Id”
5. authority{}: (not supported)

sbJSON: contacts[]>organization

i. Logic: where contactType = “organization” and “organization” block element exists = true
ii. contacts block

1. identifier: directoryId
2. namespace: displayText
3. version: (not supported)
4. description: displayText
