DSpace users are continually adding new functionality to the DSpace platform to suit their organization's needs. Some organizations/developers are willing to share their work with the larger DSpace community. The list below identifies projects that provide additional functionality to DSpace. Some of these projects are completed, other projects may become available at some point in the future for others to use. If you are working one a DSpace project that could become an addon/extension used by others, please add your project here.

Commenting

The Commenting add-on consists in a set of classes, servlets and custom tags that bring informal communication capabilities to the DSpace environment. The informal communication is assured by a threaded forum that can be attached to any DSpace resource: web-page, community, collection, submitted item or e-person. The add-on allows comments to be inserted by anonymous users as well as by authenticated ones. Functionality for reviewing comments is also provided with the add-on.

Lightweight JHOVE format validator and virus check

This patch uses JHOVE to provide rough-and-ready format checking by identifying that the file/bitstream extension matches formats verifiable by JHOVE. (Currently DSpace accepts a deposit's file extension as gospel, so a user could tack a ?.txt' extension onto a GIF and DSpace would assign the incorrect format to the file based on that incorrect extension.) It also checks the file for the presence of viruses.

CAS Single Sign-on Solution

Technical University of Denmark, http://www.cvt.dk/ Center for Knowledge Technology and http://www.nordija.com/

Enhanced DSpace with the following features:

  • Single sign-on support through CAS
  • Web service support to enable user import.

The patch (1167362) created Marts 21st 2005 consist of the following:

  • Media:files.tar.gz - includes the new files to the project.
  • Media:doc.tar.gz - contains some documentation about the two new features.
  • Media:cvt.dk.patch - the patch file.

Note that Axis requires a new version of Xerces so the existing lib/xerces.jar has to be deleted. See dspace-Patches-1167362. See CvtContribution (http://wiki.dspace.org/index.php/CvtContribution) for more information.

 

DAO+Prototype

James Rutherford

It has often struck me that DSpace would benefit from the use of Data Access Objects (DAO). If nothing else, it would make porting to alternative database platforms far easier; all we would need to do is provide alternative implementations for the DAO interfaces that worked for a given database. To this end, I have broken up some of the core classes in org.dspace.content to use DAOs. As part of the same effort, I have done some work on making the Context less data-layer dependent (by having it hold a org.dspace.storage.dao.GlobalDAO rather than a java.sql.Connection, etc). I've also introduced a proxy for the Item that is a bit smarter about when it retrieves content from the data layer, and an ArchiveManager class that takes care of some core "archive operations" (so that other core classes don't need to). The process to integration (if at all) would go as follows:

  • Incorporate the new DAO classes into the codebase
  • Refactor org.dspace.content.Item (etc) to use the DAO implementations of the data access methods internally
  • Mark relevant methods in org.dspace.content.Item as @Deprecated
  • Using the compile-time deprecation warnings as a guide, refactor the rest of the code to use the DAOs explicitly rather than hiding the functionality behind existing methods.

Without further ado, here is how I have refactored org.dspace.content.Item to use DAOs. A few important things to note:

  • "old" code has been used where possible to avoid re-implementing the wheel
  • I've never liked org.dspace.content.ItemIterator so I've switched to using a "real" Iterator from a List<Item>.

For examples of both of these principles, see the implementation of getItems() below. It is a fairly straightforward wrapper for the current Item.findAll(), except that it returns a List<Item> rather than an ItemIterator.

Delegated Admin

Delegation of permissions. DSpace currently only supports minimal distributed management at a Collection level, in the form of Collection Administrators. However, at this point in time, there is no such thing as a Community Administrator to allow for distributed management of individual Communities. The closest anyone has gotten to implement this feature is in the now out-of-date patch: Authorization System: Delegate Admins (SF#13736513) by Andrea Bollini. Tim Donohue is working on an updated version of the Delegated Admins patch that works for the DSpace 1.5.x XMLUI (it will not work for JSPUI), but I'm sure that could be added relatively easily.

SMILE DOME Integration

Extending metadata schema support in DSpace through DF/Semantic Web technologies. SIMILE seeks to enhance inter-operability among digital assets, schemata/vocabularies/ontologies, metadata, and services. A key challenge is that the collections which must inter-operate are often distributed across individual, community, and institutional stores. We seek to be able to provide end-user services by drawing upon the assets, schemata/vocabularies/ontologies, and metadata held in such stores. (SMILE related) Richard Rodgers, DSpace Semantic Web RDF data from DSpace, drop down browse, base on RDF.

Statistics

Originally from University of Rochester, modified by Mark Wood at Indiana University-Purdue University Indianapolis.

Implemented for DSpace 1.1 and shows real-time total download counts at the Repository, Collection, Community and Bitstream Levels. Also shows real-time monthly download count at all of the above except the Bitstream level.

The version at IUPUI has been modified to collect viewing events through a generic plugin interface, which means that the collection side requires only building and some slight configuration changes in dspace.conf. We have an added XMLUI Aspect to add the aggregated data to the developing page, again integrated with stock DSpace solely through configuration. It needs work on the Theme to actually expose those data on the finished page, which requires a moderate amount of XSL-T work to integrate it with any local Theme customizations. JSPUI still requires patching or overlaying. We do not yet have an XMLUI version of the administrative controls. There is an SQL script to create a few new database tables, but no modifications to the existing tables.

Toxicological Information System (TOXIS)

Belgium Poison Center

Christophe Dupriez - dupriez@squadratic.com

Integration of 5 DSpace instances/ incorporating Pubmed publishing - This project involves a large set of modifications involving 5 instances of DSpace. The current implementation is based on DSpace 1.4.2 and has been modified for speed for use in emergency situations, importation from PubMed and other sources and enhanced links management. The five instances will be used for different internal repositories that will be cross-linked. Other planned inclusions are a JSPWiki and faceted searching. Other unique modifications include auto-complete and/or use of menus to select values, tracking of the number of uses of a particular concept for diplay in links and query of authority lists.

It consists of 6 services that support the process of collection and dissemination of material in the repository by web services. These are:

  • SRW Based Search (OCLC Implementation, Ralph LeVan)
  • Upload Service
  • Download Service
  • Package Service
  • Ingest Service
  • Session Setup Service
