Should the author's id be "id" or "@id", for adding an ORCID ID?

[nsunami]

Hi! I noticed that in the README example, it's recommended to put an ORCID ID to the "id" property:

example-datasets/README.md

Line 55 in b0b7ef0

"id": "0000-0002-1825-0097" // this is an ORCID ID, e.g.

But then, in the SAFI dataset example, the author's ORCID is in the "@id" property:

example-datasets/safi-survey/dataset_description.json

Line 11 in b0b7ef0

"@id": "https://orcid.org/0000-0002-8936-0365"

Questions:

1. Which way is recommended?
2. Should the ORCID ID include the complete URL? Or should it only include the ORCID ID numbers?
