Issue
Determine mapping to use when writing mdJSON to the required DCAT-US identifier field. The field is defined as:
Description:
A unique identifier for the dataset or API as maintained within an Agency catalog or database.Usage Notes:
This field allows third parties to maintain a consistent record for datasets even if title or URLs are updated. Agencies may integrate an existing system for maintaining unique identifiers. Each identifier must be unique across the agency’s catalog and remain fixed. It is highly recommended that a URI (preferably an HTTP URL) be used to provide a globally unique identifier. Identifier URLs should be designed and maintained to persist indefinitely regardless of whether the URL of the resource itself changes.
Initial proposal is to use the following rules:
- IF
resourceInfo.citation.identifier.namespace= "DOI"- SELECT
resourceInfo.citation.onlineResource.uri
ELSE
- if "DOI" within
resourceInfo.citation.onlineResource.uri- SELECT
resourceInfo.citation.onlineResource.uri
