Hello Massimiliano,

if you change something in the source code you got to build and deploy
your application again.

Hope this helps

Dear Cluadia,
     I have changed  to Element identifier = new Element("identifier",

According to you I have to restart the system, after this change?
Thanks

Hello Massimiliano,

as Mark already pointed out there is the issue for 5.x for the schema
being hardcoded see:
https://jira.duraspace.org/browse/DS-4044
in

https://github.com/DSpace/DSpace/blob/dspace-5_x/dspace-api/src/main/java/org/dspace/identifier/doi/DataCiteConnector.java#L1039

Dear Claudia,
      The dc.identifier.uri is present in every item.
And till 2 weeks ago the doi's were mint with the schema 2.2.
Now our server doesn't mint any DOI, even with the new schema 3.
If I do  /dspace/bin/dspace doi-organiser -l  after inserting a new
item.
There isn't new doi.
Thanks
Best regards

Hello Massimiliano,

you need not add dc.identifier.uri (not doi). This is done prior to
actually registering a doi with datacite, depending on the status:


https://github.com/DSpace/DSpace/blob/dspace-5_x/dspace-api/src/main/java/org/dspace/identifier/DOIIdentifierProvider.java#L69
A newly ingested item will have the status 7:
UPDATE_BEFORE_REGISTRATION
After having run doi-organiser -u this will turn to 1: TO_BE_REGISTERED

The metadata dc.identifier.uri is set in this process


https://github.com/DSpace/DSpace/blob/dspace-5_x/dspace-api/src/main/java/org/dspace/identifier/DOIIdentifierProvider.java#L881
You can check items queued with:
[dspace]/bin/dspace doi-organiser -l

In the doi table you will see the status of the documents.
And check the logs whether something went wrong during registration and
you ended up with an inconsistent status.

Hope this helps

Claudia Jürgen

Dear Claudia,
     In this item there is no DOI but in the item submission form the
field
dc.identifier.doi is present.
And generally I leave this field blank, than after the submission and
doi
url appear on the item page after using
   /dspace/bin/dspace doi-organiser -u
Is this correct or I'm doing wrong?


Thanks

this seems  not to have dc.identifier.doi which is necessary for
registration or update

So try
[dspace]/bin/dspace dsrun
org.dspace.content.crosswalk.XSLTDisseminationCrosswalk DataCite
10556/2854 [path/to/output]

Hope this helps

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}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?

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.

- Tim

Dear Tim.

I would like to try this patch, If you tell me that I could use it

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.

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

With a schema version 2.2 it cuold be impossible to do an

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.
