[rushirajnenuji]

Hi all, this came to my attention this week, so filing a ticket in here.

The official announcement from DataCite.

Key points from the announcement: deadline: January 1, 2025 update procedure: link

There is also a webinar hosted by DataCite on March 13, 2024. sign up link

To get stats on IDs with Schema 3 versions for a specific repository (e.d.cdl.cdl) is as follows:

curl --location 'https://api.datacite.org/dois?client-id=cdl.cdl&schema-version=3'

The meta tag in the response has useful some stats:

        "providers": [
            {
                "id": "naqr",
                "title": "California Digital Library",
                "count": 3567
            }
        ],
        "clients": [
            {
                "id": "cdl.cdl",
                "title": "California Digital Library",
                "count": 3567
            }
        ],
        "affiliations": [],
        "prefixes": [
            {
                "id": "10.15144",
                "title": "10.15144",
                "count": 3510
            },
            {
                "id": "10.7293",
                "title": "10.7293",
                "count": 44
            },
            {
                "id": "10.5060",
                "title": "10.5060",
                "count": 13
            }
        ],
        "certificates": [],
        "licenses": [
            {
                "id": "cc-by-sa-4.0",
                "title": "CC-BY-SA-4.0",
                "count": 3083
            }
        ],
        "schemaVersions": [
            {
                "id": "3",
                "title": "Schema 3",
                "count": 3567
            }
        ],
        ...

However, it would be useful to get these stats fro our database as well to be thorough.
