Hi Massimiliano,

as written in the DSpace Documentation DSpace uses an asynchronous approach to 
register DOIs. Whenever DSpace wants to reserver/register a DOI, it just writes 
in the DOI table what should be done. The doi-organiser does the real work (by 
sending one or multiple requests to datacite, containing the metadata and the 
information if a doi should be reserved, registered, ...). So to send your 
registration request to DataCite, you have to run the doi-organiser as 
described here: 
https://wiki.duraspace.org/display/DSDOC4x/DOI+Digital+Object+Identifier#DOIDigitalObjectIdentifier-%27cron%27jobforasynchronousreservation/registration
To test it, you can start these commands manually on the command line. For 
regular use I would suggest a cronjob.

It's up to you to decide how often the doi-organiser should be triggered by the 
cronjob. The decision you have to make is how much time is acceptable for you 
between the moment DSpace adds a DOI to the metadata of an item and the moment 
the DOI is functional (registered). I would make this decision depending on the 
number of submissions you have per day. On smaller repositories it should be 
acceptable to run the doi-organsier perhaps twice a doi. But if you want to, 
you can run it more often, f.e. every 15 minutes...

The reason we did it this way, is to ensure that DSpace is still working even 
if DataCite should have some down time...

Did this helps you? What happens if you run [dspace]/bin/dspace doi-organiser 
-u?

Regards,
  Pascal

Hi Pascal,
  I have executed dspace doi-organiser in the wrong directory.
When I execute bin/dspace doi-organiser -l?
The system answer is:

There are no DOIs queued for reservation.

There are no DOIs queued for registration.

DOIs queued for update:
    doi:10.xxxx,10.5072/unisa-1 (belongs to item with handle 123456789/479)
    doi:10.xxxxx,10.5072/un-2 (belongs to item with handle 123456789/480)
    doi:10.xxxxx,10.5072/unisa-3 (belongs to item with handle 123456789/481)
    doi:10.xxxx,10.5072/unisa-4 (belongs to item with handle 123456789/482)
    doi: 10.5072/unisa-5 (belongs to item with handle 123456789/485)
    doi: 10.5072/unisa-6 (belongs to item with handle 123456789/486)

There are no DOIs queued for deletion.
When I go in the Datacite site, I can't see any of this item.
Thanks
Kind regards
Massimiliano

Oggetto: RE: [Dspace-tech] DOI DATACITE

Hi Massimiliano,

did you entered into a contract with a DOI registration agency? Did they 
provide you a username, a password and a (test-)prefix? Are you sure, they want 
you to use the DataCite API directly?

If you followed the instructions in the documentation, DSpace should mint DOIs 
whenever new items gets published into the repository. With "publish" I mean 
that the item is part of your repository, can be found using the normal search, 
and is not waiting for the user to finish the submission or for an 
administrator to accept it. The DOI is stored as metadata value of the item in 
the field dc.identifier.uri. So If you take a look on the published item you 
should find it there. As the documentation describes DSpace uses an 
asynchronous mechanism to register DOIs. Using the command line interface 
(https://wiki.duraspace.org/display/DSDOC4x/DOI+Digital+Object+Identifier#DOIDigitalObjectIdentifier-CommandLineInterface)
 you can list all DOIs waiting for reservation and/or registration. So, do you 
already have published an item after you configured DSpace to use DOIs? What 
happens if you executes [dspace-install]/bin/dspace doi-organiser -l?

Regards,
  Pascal

Subject: [Dspace-tech] DOI DATACITE

Hi All,

     We have installed in a test server DSPACE 4.0, we have configured it for 
the use of DOI from DATACITE.
We followed the guide line at 
https://wiki.duraspace.org/display/DSDOC4x/DOI+Digital+Object+Identifier
But now I wonder how we can test if.
Could someone give an help?
Thanks
Best regards
