Hi @paul.vierkant

I have seen a few exciting changes in 4.5, but I am wondering, in terms of uptake of the new release, What’s the expected adoption rate?

I imagine platforms and repositories must allocate resources to implement the change. I am aware that some platforms still mostly use schema 3. Are there any dissemination plans to drive the uptake of schema 4.5? and has any repository or platform committed to implementing it already?

Hi @raxik76460, thanks for asking this! We can measure adoption of the new properties and controlled list values using our REST API. Of course, we know that it takes time for platforms and repositories to adopt new schema versions—and not all properties will apply in every case.

We have plans to promote metadata completeness in general. For example, even though the Subject property has been part of the schema since its inception, approximately 59% of DOIs have Subject metadata. We’d love to see this closer to 90% for new DOIs! Also, part of our dissemination plan is to continue working with our Service Providers to encourage adoption of new schema versions in repository platforms.

I should also note that at some point, we will stop supporting schema 3 (likely around the time we release schema 5, or shortly before/after).

Could you elaborate on the “stop supporting schema 3” comment? Do you mean that the metadata won’t be accessible and deposits won’t be possible?

I would also be interested to know which service providers (or other platforms) are committed to implementing the new version.

Thanks for sharing

Thanks for the reply @KellyStathis

That is true with other properties. Distribution in 4.5 is different, right? Most, if not all, DOIs would have a Direct Object that the landing page is referencing. Potentially metadata deposits in all past versions (major and minor) can share Distribution metadata.

Do these efforts include the transition of repositories that currently deposit metadata in 3.X to use DataCite’s approved service providers?

It would be interesting to learn more about how DataDite creates uptake of this change.
