Re: [Dspace-tech] REST Based Integrations with Moodle / LMS / CMS / LTI

[emilio lorenzo]

Hi Peter

we have a live integration between Moodle and Dspace,  see 
http://www.arvo.es/en/dspace-products/107-modulo-de-integracion-con-moodle 
The integration was made in 2013 extending an unofficial REST (to allow 
CRUD operations)  and extending an small Moodle module already avaliable 
somewhere  The module allows to deposit learning materials from 
Moodle to Dspace and also for searching-retrieving from dspace.
Of course we had to extend the (Hedtek code?, i must check this) REST 
with some additional endpoints. Later we checked it against the new REST 
interface available in V5, and we did not miss any important 
functionality...


Best regards

Emilio

Hi All,

I was wondering if anyone is aware of any integrations between DSpace 
and other systems out there. I've heard from various groups wanting to 
integrate their CMS (Wordpress, Joomla, Drupal), or LMS (Canvas, 
Sakai, Moodle, BlackBoard, D2L) with DSpace, to re-use content 
archived in DSpace and publish it in a course, or in a guide, or on 
their website. Or even to search their DSpace from their site. I've 
seen various plugins or modules for various platforms, but I'm not 
aware if current/official DSpace is off-the-shelf compatible with 
other systems. While the "unofficial" REST API's for DSpace have been 
used for integrations past, present, and future they haven't been 
included in the official release of DSpace, posing an additional 
hurdle to a campus that has DSpace + some other system.


I'd be curious if anyone has first hand experience, or is aware of a 
list of missing endpoints for the current API (workflow, users, etc) 
that is limiting their ability to successfully integrate.

[Dspace-tech] Sobre instalación de Dspace 5.1 en W7

[Yelena Islen San Juan]

Buenas tardes:

Estoy instalando la versión 5.1 de dspace para Windows, siempre lo había 
instalado en Linux, por lo que no estoy familiarizada en Windows. Al final de 
la instalación me sale lo siguiente, pero no se crean las tablas en la base de 
datos y en el directorio C://dspace no se crean las carpetas correspondientes.  
 Espero atentamente su respuesta.

[Dspace-tech] Embargo Question

[Matt Sherman]

Hi all,

I worked with my first embargoed item today, and I think when it was
embargoed at the metadata record level as well as the bitstream level.
I really only need it embargoed at the bitstream level not to violate
the publisher's copyright terms.  Does anyone know if it is possible
to edit the embargo settings in the administrator UI?  Or does this
need to be done in the command line?  I have not seen anything and a
Google search is not giving me helpful results so I thought I would
ask the group.  Thanks for any insight.

 so the individual media filters don't have to account for this permission
 feature.

 I did figure out what the issue was though. You have to use the
 condensed name of the media filter task (without spaces,
 ImageMagickPdfThumbnailFilter), and not the expanded name (ImageMagick PDF
 Thumbnail) in filter.org.dspace.app.mediafilter.publicPermission

Re: [Dspace-tech] Generate publicly accessible thumbnails of restricted content

[Alan Orth]

Hilton,

Your 4.x docs seem to suggest publicPermission is available in DSpace 4.x,
but it's not. I was very happy when I read your docs, until I grepped the
4.3 source tree for `publicPermission` and got no hits. :)

Seems it's a DSpace 5.0+ feature:

Alan

Re: [Dspace-tech] Database Migration from Dspace 1.4.1 /postgresql-8.2.3 to Dspace 5.1/Oracle 11gR2.

[Tim Donohue]

Hello Vineet,

You may be better off asking on Oracle mailing lists how to migrate from 
PostgreSQL to Oracle, as that seems like the hardest part of this 
migration. I'm unaware of any tools that make this easy, but there seems 
to be some discussions about migrating from PostgreSQL in the Oracle 
Community Directory:

https://community.oracle.com/search.jspa?q=migrate+from+postgresql&customTheme=

Unfortunately, DSpace has no easy way to help you with such a database 
migration. But, if you were willing to upgrade to DSpace 5.1 + 
PostgreSQL FIRST, then you could use DSpace's export tools to simply 
export all its content, and then re-import it into a new copy of DSpace 
5.1 + Oracle.

That process of exporting content from DSpace 5.1 + PostgreSQL & 
reimporting into DSpace 5.1 + Oracle would look like this:
1) First upgrade from DSpace 1.4.1 to DSpace 5.1 (keeping the database 
on PostgreSQL during this upgrade)
2) Export all the content as AIPs from DSpace 5.1 + PostgreSQL. See this 
command: 
https://wiki.duraspace.org/display/DSDOC5x/AIP+Backup+and+Restore#AIPBackupandRestore-ExportingEntireSite
3) Install a fresh (empty) version of DSpace 5.1 + Oracle.
4) Finally, *Import* all the AIPs (which were exported in step #2) into 
the DSpace 5.1 + Oracle instance. See this command: 
https://wiki.duraspace.org/display/DSDOC5x/AIP+Backup+and+Restore#AIPBackupandRestore-RestoringEntireSite

Good luck,

Tim

Re: [Dspace-tech] Saving a submission throws an exception

[Jozef Misutka]

I will try to answer our own question with details and a little bit of
guessing.


Our repository is based on DSpace 5.2-SNAPSHOT, we are using xmlui and
users submit items using submission workflow.
We are notified by mail about cocoon exceptions because we are using
exception generator similar to the following

public class EmailExceptionGenerator extends ExceptionGenerator {
   private static final Logger.own_logger log = (Logger.own_logger)
Logger.getLogger(EmailExceptionGenerator.class);

   @Override
   public void generate() throws IOException, SAXException,
ProcessingException {
  super.generate();
  if(this.parameters.getParameterAsBoolean("send_email", false)){
 Throwable t = ObjectModelHelper.getThrowable(objectModel);
 log.send_error(t);
  }
   }
}

As Ondrej pointed out, the exception in the original email can be
reproduced on a clean DSpace 5.2 by
1) starting a submission;
2) click on Save & Exit;
3) click on Save it, I'll work on it later;
4) checking cocoon logs.

Afterwards, cocoon log will contain an exception similar to

cocoon.handled  - Could not read
resource 
cocoon://DRI/3/handle/123456789/214/submit/8479132f42322b784f445968356a223307411f37.continue
at  -
resource://aspects/Statistics/sitemap.xmap:359:36
... cca 180 lines of stack trace ...
Caused by: java.lang.NullPointerException
   at
org.apache.cocoon.components.source.impl.SitemapSource.init(SitemapSource.java:292)
... cca 170 lines of stack trace  (happy debugging) ...


Simply said, DSpace uses cocoon and cocoon uses sitemaps and aspects
meaning you start in the main sitemap and traverse aspects that somehow
match e.g. by uri.
In the process, DSpace java or javascript can be called. DSpace uses DRI
schema document [1] and that document get be updated using the
functionality defined by aspects.

Looking at our exception, the prefix DRI/3 means that the 3-rd aspect
caused a problem. The exception is misleading in this case because the
culprit is not mentioned there (DRI/3 is *not* the Statistics aspect).

Turning cocoon debugging on [2] gives more details.

2015-05-19 08:51:56,705 DEBUG

PARAM: 'aspectName' VALUE: 'Submission and Workflow'


After some more debugging [3], we find this in the submission.js:
submitStepSaveOrRemove called while executing the aspect

 if (cocoon.request.get("submit_save")) { // Already saved... var
contextPath = cocoon.request.getContextPath(); cocoon.redirectTo(contextPath
+"/submissions",true); cocoon.exit(); }

The redirectTo sends redirection to the browser, which means you will
*never* see any exception after this point in your UI.
Cocoon exit is calling FOM_Cocoon.suicide().
Later, SitemapSource does not have this.pipelineDescription.
processingPipeline initialised properly from which comes the
NullPointerException.
With some amount of guessing [4],  the suicide method is the reason for all
of this (in general, suicide is not a solution).
There are more exceptions generated afterwards.

You can also try to Cancel Creating a collection which has the redirectTo +
exit and it will produce the same error. Note that although there are
several redirectTo only a few can be really reached (use [3]).

function startCreateCollection()
{
   var communityID = cocoon.request.get("communityID");

   assertAuthorized(Constants.COMMUNITY,communityID,Constants.ADD);

   doCreateCollection(communityID);

   // Root level community, cancel out to the global community list.
   cocoon.redirectTo(cocoon.request.getContextPath()+"/community-list",true);
   getDSContext().complete();
   cocoon.exit();
}

If I had time, I would experiment with a setup where the last aspect is the
one calling cocoon.exit.

Best,
Jozef




[1]  You can retrieve them appending ?XML to the url or using url
../DRI/... (they are not the same though)
[2] See https://jira.duraspace.org/browse/DS-239
[3] There are more ways how to debug interpreted javascript in cocoon but
one simple way is to add breakpoints to the underlying java e.g.,

cocoon.redirectTo(contextPath+"/submissions",true);

can be found in cocoon-flowscript-impl::FOM_Cocoon.jsFunction_redirectTo which
can be found in External Libraries (depends on your IDE).
[4] I am not a cocoon expert (luckily) and I have neither the time nor the
will to intimately debug a dead project so some guessing is involved.

Re: [Dspace-tech] eperson and groups

[helix84]

I don't think it's doable with the currently available CLI commands in
DSpace:
https://wiki.duraspace.org/display/DSDOC5x/Managing+User+Accounts

You could, however, use a CLI SQL client (psql) to manipulate membership in
the epersongroup2eperson table. You can find out the user and group IDs
from the eperson and epersongroup table, respectively.

Alternatively, assuming you're using password authentication and want to
put all users into a single group, you can use the login.specialgroup
option in [dspace]/config/modules/authentication-password.cfg. Please note
that special group membership is dynamic - it doesn't appear in the
epersongroup2eperson table, but you can check effective membership in the
profile of a logged in user.

~~helix84

[Dspace-tech] eperson and groups

[Vegard Korvald]

Hello,

I'm new to DSpace and would be very greatful if one of you could help me with 
an issue.

Is there a way to add an eperson into groups by using the command line tool or 
in any other way script it so that we dont have to do it manually? I know 
there's a solution with LDAP+AD, but unfortunately we can't use this method 
because we can't authenticate with LDAP.
