Hello Massimiliano,
we are running DSpace 5.x with DataCite 4.1 (heavily relying on our own
metadata and thus not yet backported to DSpace).
Prior to this we had DataCite 3.1 with no problems.
You can test your crosswalk by crosswalking an item with:
[dspace]/bin/dspace dsrun
org.dspace.content.crosswalk.XSLTDisseminationCrosswalk DataCite
[YOUR-HANDLE] [path/to/output]
and then validating the resulting xml
That is allways advisable prior to changing the one in production.
The difference between 5.x and 6.x is that in 6.x some things like the
namespace was made configurable which was prior hardcoded in the
DataCiteConnector.
Hope this helps

Hi Massimiliano,
The main error message there seems to be this one:
While reserving the DOI doi:10.10xxx/un**-1194, we got a http status code
422 and the message "This element is not expected. expected is one of ( {
http://datacite.org/schema/kernel-3}identifier, {
http://datacite.org/schema/kernel-3}creators, {
http://datacite.org/schema/kernel-3}titles, {
http://datacite.org/schema/kernel-3}publisher, {

http://datacite.org/schema/kernel-3}dates, {
http://datacite.org/schema/kernel-3}language, {
http://datacite.org/schema/kernel-3}resourcetype ).
That error is saying that the DataCite API seems to be returning a 422
(Unprocessable Entity) Response with an error message that says "This
element is not expected" and a list of expected elements.
I'm going to admit, I'm not familiar myself with the DataCite service or
this DOI connector in DSpace. (It was written & tested by other developers
-- DSpace is a community-wide effort, and I'm unable to review every line
of code.) It's possible either the patch you applied didn't full "work"
for DSpace 5.6, or maybe there's another fix in DSpace 6.0 that I
overlooked that provides compatibility with DataCite schema 3.x
Does anyone else on this list have experience in using the DOI connector
with DataCite Schema 3.x in either DSpace 6.x or 5.x? I'm wondering if
someone else may have seen errors of this sort before, or perhaps can
confirm that DSpace 6.x works fine with DataCite Schema 3.x?

Dear Tim,

But the answer after

Hello Massimiliano,
Since you are running DSpace 5.6, you'd have two options to get to
DataCite v4.1 compatibility:
- Either you should upgrade to DSpace 6.3 (the latest version of
6.x), and then apply this patch
https://github.com/DSpace/DSpace/pull/2321
- Or, you would need to apply *two* patches to DSpace 5.x. First,
you'd have to apply the fixes to update to DataCite schema v3.1 :
https://github.com/DSpace/DSpace/pull/1197 (This is the fix that was
included as part of 6.0). Then you would need to apply this patch:
https://github.com/DSpace/DSpace/pull/2321
You also may want to simply see if upgrading to DSpace 6.3 would *solve*
the issues you are having. In your original email, it was unclear if you
absolutely *must* be running DataCite schema v4.1, or if possibly DataCite
schema v3.1 would work. So, honestly, my recommendation would be to first
start up a test server with DSpace 6.3 on it to see if compatibility with
DataCite schema 3.1 fixes the issues you are seeing. If so, you may not
even need to apply the patch to update to DataCite schema 4.1. I cannot
give advice myself on whether upgrading to DSpace 6.3 will solve the issue
or not -- that's likely something you'd need to either test out yourself,
or talk to the DataCite team about.

Dear Tim.
I'm running DSpace 5.6 I could install this patch on it?
I would like to try this patch, If you tell me that I could use it only
on DSpace 6.0 I'll try it first on a test server with DSpace 6.0.
If I can I'll try to help for this patch with some notes about it.
Thanks
Best regards

Massimiliano,
Just a follow-up to Mark's previous note. DSpace 6.x is using DataCite
Schema 3.1 (so if you are seeing Schema 2.2, I'm assuming you aren't using
the latest DSpace), see this update which was released in DSpace 6.0:
https://jira.duraspace.org/browse/DS-2924
As Mark notes, we have a pending update to DataCite Schema 4.1, which
likely won't be released until 6.4 (at the earliest). If you are already
running DSpace 6.x, this patch should be relatively easy to apply
immediately. If you are able to help test this patch, then we'd appreciate
it if you could add notes to the patch (in GitHub), as that will allow us
to more easily approve/merge the change in time for 6.4. Again, here's
where this patch is: https://github.com/DSpace/DSpace/pull/2321
If you have further questions, let us know on this list.
Tim

The DOI Datacite schema now is arrived to 4.1, we have on
DSpace version 2.2 and it could have some problem with the new managemant
software of DATACITE.
With a schema version 2.2 it cuold be impossible to do an update via
the "DOI DataCite Fabrica" system.
So I would like to know if it is possible to update this schema to
4.1.
There is a patch to upgrade to 4.0:
https://github.com/DSpace/DSpace/pull/2321 which has not yet been
merged.
