This documentation relates to release candidate version of the DataCite DOI plugin, available at 
DataCite DOI Manager Screen
The process for registering and minting DOIs is now managed via the DataCite DOI Manager screen, available via an eprint item’s Actions tab.
The DataCite DOI Manager is only available for items in the review queue or the live archive, and only to those users with editor or administrator permissions.
Each eprint record has its own DOI that can be registered with DataCite, derived from the repository’s DataCite prefix (e.g. 10.xxx), the repository’s name, and the eprint’s ID.
If this DOI has not yet been registered on DataCite, it will be listed as an Available DOI, and is available either to reserve or mint:
- Reserve: The DOI is created in DataCite as a Draft DOI. The DOI is not listed in the global handle system and is not publicly findable.
- Mint: The DOI is registered with the global handle system and listed as Findable in DataCite.
Items in the repository’s review queue may only have DOIs reserved. Not all of the mandatory metadata is required when reserving a DOI.
Clicking the Reserve DOI button will create a draft DOI in DataCite. This process happens instantly and the DataCite DOI Manager screen will update to show when the DOI was reserved as well as adding the DOI to the item’s DOI metadata field. Draft DOIs are not registered against the global handle system, i.e. they won’t redirect to the eprint. Once a reserved DOI has been created it can be updated with the item’s current metadata.
Minting a DOI adds it as a findable DOI in DataCite. There are two main approaches to minting a DOI:
- Using the Mint DOI button for an item in the live archive, which has all of the required metadata.
- Transferring an item with a reserved DOI and all of the required metadata, to the live archive, from the review queue.
The Mint DOI button will register the DOI with the global handle system, and the DOI will be registered as “Findable” in DataCite. This process may take a few minutes and is handled by the repository’s indexer. Upon successful completion the new DOI will be added to the eprint’s DOI metadata field.
Once a DOI has successfully been minted for an eprint, the option to Update Metadata becomes available, which will resend the eprint metadata for this DOI.
This should only be used for minor updates, e.g. correcting errors or adding additional files.
If an item which has previously had a DOI minted for it is either retired or removed from the repository, the DataCite record is updated to point to a tombstone page for the record. This consists of the basic citation metadata that was last registered with DataCite, i.e. the data available when either of the Mint DOI or Update Metadata buttons was last used.
When creating a new version of an eprint via the New version button in the Actions tab, any existing DOI value will be copied across to the new version of the eprint.
The DataCite DOI Manager will highlight when a Current DOI redirects to an earlier version of an eprint, and will present two options when the later version is in the live archive (i.e. has a page a DOI can successfully redirect to).
- Update Metadata & URL – this will update the current DataCite record to redirect to the new version of this eprint
- Reserve DOI and Mint DOI – the regular options available when the Available DOI for a record has not yet been reserved or registered on DataCite.
DOIs registered for eprints which are earlier or later versions of other eprints, will use DataCite’s “HasVersion” and “IsVersionOf” properties to link forwards and backwards as appropriate.
If an eprint already has a DOI associated with it, e.g. one that has previously been provided by a journal publication, then this will be listed as the Current DOI. The DataCite DOI Manager screen will indicate where this DOI redirects to, and will still present options for an Available DOI if the DOI for this record can still be minted on DataCite.
The DataCite DOI Manager will also run a search of the eprint’s title against DataCites findable records, to see if a DOI has been coined previously. If one of the records matches the eprint, the Claim DOI button will set the eprint’s DOI metadata field to the DOI already on DataCite.
All of the above features are also available for documents uploaded to a repository. DOIs must resolve to a landing page about the record they identify, and as such these features are only available for repositories with document landing pages enabled.
