The following is the use case of my process.
@MohanaPriyaNarapareddy hi! It's funny, @amberleahey @johnhuck @jggautier and I were just talking last week about #2146 and how the name of the root dataverse appears as the publisher in the citation.
http://guides.dataverse.org/en/4.14/installation/config.html#branding-your-installation currently says this:
"The name of your root dataverse is the brand of your installation of Dataverse and appears in various places such as notifications and support links..."
One of the "various places" is the citation! 馃槃 This should be documented.
Here's a screenshot from #2146 that shows that in DVN 3 the citation used to include the name of the parent dataverse ("Massachusetts Archives, Boston MA") but that now in Dataverse 4 the name of the root dataverse ("Harvard Dataverse") is shown:

@pdurbin The Root that @MohanaPriyaNarapareddy is referencing is the value that populates in the Datacite metadata. Take a look at this JSON document:
https://api.datacite.org/dois/application/vnd.datacite.datacite+json/10.7937/k9/tcia.2018.15quzvnb
This is the metadata for one of the DOIs that we imported (we are migrating from an in-house solution to Dataverse). When this was published via Dataverse it changed/set the publisher to Root. We'd like it to be The Cancer Imaging Archive
Would it be possible to change the branding of your Dataverse from "Root" to "The Cancer Imaging Archive"?
Sure. I don't care for Root But would changing the branding also reflect in the documents that are sent to Datacite?
After adjusting the name of your root dataverse (changing to from "Root" to "The Cancer Imaging Archive" or whatever), you can re-sent the metadata to DataCite using this API endpoint: http://guides.dataverse.org/en/4.14/admin/dataverses-datasets.html#send-dataset-metadata-to-pid-provider
It should work anyway. I haven't actually tested it myself. 馃槃 This feature was added as part of #5060 in Dataverse 4.10.
In addition to re-sending metadata to DataCite using the API endpoint that @pdurbin pointed out, after the installation branding is changed, when new datasets are published or new versions of existing datasets are published, the metadata that Dataverse sends to DataCite will include the new installation name in DataCite's "producer" element.
Hi @MohanaPriyaNarapareddy and all - I'm going to close this out as it seems from above conversation that there's a solution and no code changes are needed. Thanks for the good discussion and please repopen this if I'm wrong. :)
@MohanaPriyaNarapareddy - if you have a Dataverse installation that's not on the map at dataverse.org and you'd like it added, please feel free to reach out to us at [email protected]!
@djbrooke Thank you. And yes, as soon as the installation goes live, we will ping support
