Re: [Dspace-tech] Development goals
Dear Michele (copy to the community), May be I am basically wrong seing DSpace as a community of practice making a tool to promote the dissemination of the good Open Repositories practices. If I understand correctly your plans, DSpace is primarly a community of developpers where users requirements are tackled inside individual institutions and mostly technical problems are shared outside. I am sorry that my dream is different but I will play the real game ! I will follow the Claudia Juergen's advice: Small contributions are beautiful. To be constructive and pragmatic, my main technical challenge remains: adding thesaurus based query expansion to DSpace to be able to mimic PubMed searches exhaustivity and precision in DSpace (we now have 75 thousands documents in our internal repository. MeSH is 30 thousands subjects headings). I will keep focused on this. Have a nice day! Christophe Michele Kimpton a écrit : Dear Christophe and DSpace community, One of the main projects the Foundation ( not federation, and I point this out as they are completely different) has taken on is to put together a team from the community and get funding for DSpace 2.0. The work to be done will involve core architectural changes- under the hood, so to speak- that will be somewhat transparent to many end users. However, these changes will have large implications down the road, in a good way, for the community at large. One of the complaints is to be able to easily change the UI, or create multiple UI's, Web 2.0 interactions,ect., is due to the fact the code is not modular ( as Tim points out). One of the main goals of 2.0 is to make it more modular so organizations can plug and play, meaning choose the interface(s) they prefer. It also allows many more developers to participate in the process- as their contributions can be rolled into the releases much more easily, given the code will not have complex interdependencies with the rest of the core code ( we hope). If we are successful in putting together a modular architecture- than we can have multiple UI's, asset stores, workflows ect. As there are no dedicated developers within the community or the Foundation working full time on DSpace- it is important to empower the community to be able to contribute code that fits their organizational needs- and therefore we must put an architecture in place that supports this process. We hope to start the work for DSpace 2.0 this winter. Once 2.0 is in place we can start a process where users can assess user needs and feature requests(developers can do this now on source forge) but realize the work to develop those features will still need to be done within the community, and maybe the community will be willing to pay for development time to make it happen collaboratively, but that remains to be seen. I plan on hiring a Technology Director within the Foundation to help lead this process(2.0 and beyond). We have secured some of the funding and developer time to do the work required. I hope to secure the remaining funding needed over the next few months. If anyone in the community would like to help me in this process( getting funding, donating developer time, volunteering I welcome your help. sincerely, Michele DSpace Foundation Director On Nov 15, 2007, at 3:09 AM, Christophe Dupriez wrote: Hi Tim, (copy to Michele, Dorothea and the Tech list) Thanks for your views and congratulations for your work with IDEALS.

Re: [Dspace-tech] Batch Import and Namespaces
Hi Don,
thanks for You reply. Sorry for my late response, but the XML-import
seems to me at first as a more official way to do it then using the
csv-package. And so I tried it as first. Now I see both ways have their
advantages and disadvantages (not surprisingly), and I took up Your
thread and looked into ItemImport.java. I succeeded! The changes I made
are below. To add the 'schema'-attribute to every dcvalue tag if
needed the 'fls.php' needs also some little changes. They are also noted
below. The disadvantage of this method is that every imported metadata
value gets a default language qualification. And in most cases it makes
no sense (eg. dates, index numbers or names) or it is wrong (from a
keyword list). The metadata generated by DSpace don't have these
qualifiers (it is set to '-').
Best Regards
Robert

fls.php:
function create_tag($schema, $identifier, $qualifier, $value){
$schemaAttrib = ;
if ($schema != 'dc') {
$schemaAttrib = schema=\$schema\;
}
$dc_tag = dcvalue$schemaAttrib element=\$identifier\
qualifier=\$qualifier\$value/dcvalue;
return $dc_tag;
}
# and the call it with the additional first parameter (two times):
#create_tag($dc[0],$dc[1],$dc[2], ...)
ItemImport.java:
/*
Node schemaAttr = metadata.item(0).getAttributes().getNamedItem( schema);
if (schemaAttr == null)
{
schema = MetadataSchema.DC_SCHEMA;

Don Gourley schrieb:
Robert,
The problem is that a bug in ItemImport prevents you from mixing
different schemas in the same dublin_core.xml file. The loadDublinCore
method gets the schema from the first dcvalue tag and reuses it
for every metadata element. But it is a pretty easy Java fix to
move 'schema = schemaAttr.getNodeValue();' from outside the loop
that traverses the dcNodes list to inside that loop so it is
retrieved for each metadata element if you need to mix schemas.
(Sorry, I don't have a patch because we use a more substantially
rewritten ItemImport for other customizations.)

[Dspace-tech] Differences between the data model and the trunk
Hi all, I'm writing to underline some differences between the data model shown in the dspace site ( http://www.dspace.org/index.php?option=com_contenttask=viewid=149#data_model ) and the actual code present in the /trunk ( http://dspace-sandbox.googlecode.com/svn/mirror/dspace/trunk/ ). There are differences in the associations between objects of the model: some one-to-many associations in the model are replaced in the code by many-to-many ones. I found 3 examples: - In the model, a Collection can be owned by only one Community, whereas in the code a Collection can be owned by many Community. - In the model, a Bundle can be owned by only one Item, and in the code it can be owned by more then one Item - In the model, a Bitstream can be owned by only one Bundle, and in the code by more then one. In the database schema, all the associations are many-to-many, there are no restrictions. I also looked at Jim's DAO-prototype ( http://dspace-sandbox.googlecode.com/svn/branches/dao-prototype/ ), and he reflects the database schema, using only many-to-many associations. I'm working on a prototype to introduce Hibernate, and i'd base my work on Jim's choice, but i'd like to have some opinions about it, what should we do? update the data model associations? follow the model and update the code in /trunk? what kind of associations should be kept and what dropped? My mentor Andrea will write his opinions replying to this email, to let everyone know them. We both are interested in having other opinions to choose the best way to go ahead.

Re: [Dspace-tech] Viruses and DSpace
Has any thought been given to how Dspace might handle the remote ( hopefully ) possibility of a file containing a virus being deposited into a repository? It seems like jhove might be the kind of tool that could check for this. I believe there is some work going on to incorporate jhove into Dspace, how is that coming along? It's not part of of 1.5, but what about for the following release? The BitstreamFormat renovation (see http://wiki.dspace.org/index.php/BitstreamFormat_Renovation ) doesn't address this directly, but will make it much easier to integrate tools because file formats will be identified more effectively and precisely. Once the format is known you can add a mechanism like the mediafilters, perhaps integrated with workflow, to run specific checks depending on the format type. JHOVE version 1 is just a format validator and technical-metadata extractor, it isn't subtle enough to look for viruses. There _are_ tools in the email filtering domain which detect malicious MS Office files; I've heard of them but don't remember specifics. You could start by looking around the SpamAssassin software and ClamAV (see http://www.clamav.net/ ) However, be aware that any virus-checking software needs constant updating since you're essentially in an arms race. -- Larry (a recovering postmaster) - This SF.net email is sponsored by: Microsoft Defy all challenges.

No. I think your right on in this regard, but just not one tool, many tools that work collaboratively. Yet, also to be a good participant in a larger community of existing tools and platforms.

I am sorry that my dream is different but I will play the real game ! I will follow the Claudia Juergen's advice: Small contributions are beautiful. I think we need to be careful about these definitions. The DSpace Community is a reflection of what its members need and want in an organization of users, managers and developers around the DSpace platform. The most salient roadblock to increasing the transmission of community enhancements into the codebase is that DSpace was basically a monolithic platform with a centralized build process. A significant bottleneck existed (and may still exist until we have a SCM and Issue tracking system that is scalable in terms of Access control) in that the commiters managing the process of reviewing and getting changes into the codebase supplied by the community as patches. The developers who are commiters are so because they want to participate more intimately with the future direction of DSpace. The previous viewpoint that commiters were basically servants or gate-keepers to the contributor community is both ill-fitting and unrealistic because a large number of the commiters are actually emeritus in their behavior and not very active, leaving much of the work in the role of gate-keeper actually to the newly elected commiters. Thus the paradox and the bottleneck. The actual and ideal maintainers, shepherds or stewards of the community are not on the continuum of commiter vs. contributor, but actually on the continuum of active vs. inactive! We need a better process for shifting the dial to the active side. To be constructive and pragmatic, my main technical challenge remains: adding thesaurus based query expansion to DSpace to be able to mimic PubMed searches exhaustivity and precision in DSpace (we now have 75 thousands documents in our internal repository. MeSH is 30 thousands subjects headings). I will keep focused on this. You should be more aggressive in participating in the community on something like this, prod the community to get more participation, and be flexible about the final outcome. I think you'll find that there are other developers in the community with the same interest. It would behoove you and them to get out of the woodwork and have real transparent conversations together on the community lists (hint hint, nudge nudge, Richard Rodgers). Cheers, Mark ~ Mark R.

Re: [Dspace-tech] DSpace Installation Saga: Please Help!
Hello, I guess you get several helpful hints here, but they go slightly different ways to get results. I guess you have to pick just one way and go along with it. The most natural approach for me with my knowledge seems to be the one Kyle suggests. So far, you try to set up the whole thing at once, including postgres, tomcat, apache and mod_jk. For now, just forget about apache. If you can see your pages under tomcat directly you can try to integrate with apache via mod_jk later on. You can even forget about postgres for now, because you will see a dspace error message in your browser if dspace cant connect to the database. But that is certainly not your problem because you have proven that it works by running fresh_install successfully. You listed your version numbers in the first post and I wondered how you had been able to build dspace when you had only a JRE installed but as it worked you should have a javac in place. You might check this. If my understanding ist fine, the tomcat JSP container uses this javac to compile JSPs at runtime. This is, it wont work properly without a JDK installed. Prove me wrong. Did you compile dspace on the same machine? You probably have ant installed in a recent version? You can see the tomcat homepage which means that tomcat is running. It also recognizes the .war files and unpacks them which means that automatic deployment is working too. Surely, there is no permissions problem at this point. tomcat only reads the .war files, so they can be owned by anybody as long as everybody may read them. While tomcat unpacks these files, it has to be allowed to write to the /webapps dir which it obviously is. It is probably allowed to write to /work which it needs to run any .jsp. You might want to check this. The files tomcat writes to /webapps/dspace are then owned by tomcat which is fine. The only thing not discussed so far is the dspace install directory. You should check whether tomcat is able to write to /dspace-install/assetstore or /dspace-install/history and so on. DSpace is not running which means that you dont have a dspace.log which in turn means that you dont have detailed error messages. If I am wrong with my JRE vs. JDK idea, then the only thing where you can find a fault is in your dspace configuration files. The web.xml does not get changed during a default install, so I would just replace it with the default version if you edited that. Then check the first third of your dspace.cfg file which contains all the important path, database and email settings. The rest of this file deals with special datastores, different thumbnail display and cosmetic stuff. The last thing to look at besides dspace.cfg is the log4j configuration file for dspace. Check whether it makes sense to you. I hope you can find the culprit. Bye, Christian Am 16.11.2007 um 02:59 schrieb Drrty Byl: Thanks Graham.

Easiest thing would be to delete it and start again, but wondered first if there was another angle. Does the error even refer to the contents of element /rss/channel/description (which is empty even in feeds that don't throw errors) - or to something else?

Re: [Dspace-tech] OpenSearch support?
Mark H. Wood wrote: There's interest here in adding OpenSearch support to our DSpaces. I found some two-year-old pages suggesting the possiblity of such, but the author seems to have moved on. There's no mention of OpenSearch on the DSpace Wiki. Has this been done? That depends on what you mean by support... Writing an OpenSearch plugin for an individual DSpace should be really easy, since DSpace uses parameterized URLs for searches. See, eg: http://gizbuzz.co.uk/2007/making-your-own-opensearch-plugins/ Performing a simple / advanced search on your DSpace instance and inspecting the URLs should make it pretty obvious what you need to do. cheers, Jim -- James Rutherford | Hewlett-Packard Limited registered Office: Research Engineer | Cain Road, HP Labs | Bracknell, Bristol, UK | Berks +44 117 312 7066 | RG12 1HN.

Re: [Dspace-tech] how to create a non-interative submission step in manakin
Hi Tim,
Thanks for the information. I have tried to create a non-interative step by
following the instructions. It doesn't seem difficult. However, the DSpace
will hang there whenever I click the submission or submit to this
collection button.
Here is what I did. Can you point out where I'm doing wrong?
===
public class NonInteractiveStep extends AbstractProcessingStep
{
/** log4j logger */
private static Logger log = Logger.getLogger(NonInteractiveStep.class);
/**
* Do any processing of the information input by the user, and/or
perform
* step processing (if no user interaction required)
* P
* It is this method's job to save any data to the underlying database,
as
* necessary, and return error messages (if any) which can then be
processed
* by the appropriate user interface (JSP-UI or XML-UI)
* P
* NOTE: If this step is a non-interactive step (i.e. requires no UI),
then
* it should perform *all* of its processing in this method!
*
* @param context
*current DSpace context
* @param request
*current servlet request object
* @param response
*current servlet response object
* @param subInfo
*submission info object
* @return Status or error flag which will be processed by
* doPostProcessing() below! (if STATUS_COMPLETE or 0 is
returned,
* no errors occurred!)
*/
public int doProcessing(Context context, HttpServletRequest request,
HttpServletResponse response, SubmissionInfo subInfo)
throws ServletException, IOException, SQLException,
AuthorizeException
{
boolean multipleTitles = false;
boolean publishedBefore = true;
boolean multipleFiles = false;
// If step is complete, save the changes
subInfo.getSubmissionItem().setMultipleTitles(multipleTitles);
subInfo.getSubmissionItem().setPublishedBefore(publishedBefore);
subInfo.getSubmissionItem().setMultipleFiles(multipleFiles);
// commit all changes to DB
subInfo.getSubmissionItem().update();
context.commit();
return STATUS_COMPLETE; // no errors!
}
/**

method
* is used to build the progress bar.

* This method may just return 1 for most steps (since most steps
consist of

* step which spans across a number of HTML pages. For example, the

overrides
* this method to return the number of pages that are defined by its
* configuration file.
* P
* Steps which are non-interactive (i.e. they do not display an
interface to
* the user) should return a value of 1, so that they are only processed
* once!
*
* @param request
*The HTTP Request
* @param subInfo
*The current submission information object
*
* @return the number of pages in this step
*/
public int getNumberOfPages(HttpServletRequest request,
SubmissionInfo subInfo) throws ServletException
{
// always just one page of initial questions
return 1;
}
}
I simply modified the InitialQuestionsStep.java
Here is what I have in item-submission-XMLUI.xml file:
=
!-- This is a non-interactive step which has no UI --
step
heading/heading !--can specify heading, if you want it to appear
in Progress Bar--
processing-classorg.dspace.submit.step.NonInteractiveStep/processing-class

/step
!--Step 1 will be to gather initial information--

Ying,
Take a look at the docs/submission.html documentation with DSpace
1.5alpha.
Near the end of that documentation, there are tips on Creating a new
Submission Step. If you only implement the required items (#1 #4
in that list), you will end up with a
