In sample profile landing page, we need to add a block of JSON-LD. JSON-LD REST API will create json-ld block of text according IGSN.

Tested successfully with IESER0010. I was able to download the JSON-LD file (See attached; converted to txt as GitHub will not support JSON files).

Will let user download private/restricted IGSNs. Example, IESER000V.

Fixed. I also fixed a bug that the registrant was repeated twice.

Test successful. Private IGSN now returns a message that the sample is private. See below.
