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.

Dublin Core Meta Toolkit
The Dublin Core Meta Toolkit transforms data collected via different methods into Dublin Core compatible meta data. The Toolkit is ideal for converting formats from Microsoft Access, MySQL and comma delimited value (CSV).

Lightweight Network Interface
A simple but comprehensive network interface that was developed as part of the CWSpace project. It was designed to be complete enough for most programmatic uses of the DSpace API, particularly submitting and extracting archived materials as packages or byte streams.
1.5.2

Larry Stone from MIT

Controlled Vocabulary/Ontology
Allows the user to choose from a predefined taxonomy of keywords to describe items of information that are being submitted to the repository. That same taxonomy is used to find and access items held in the repository.

University of Minho

Request Copy
The purpose of this feature is to increase both the content deposited in an IR and its immediate usability by providing a way to accommodate the (frequently unfounded) worries of authors and their institutions about copyright infringement during any publisher embargo periods on public self-archiving, by creating a semi-automated mechanism whereby would-be users can request and authors can email an individual copy of a full-text deposited with access set as A.

Semantic Search for DSpace
Semantic Search allows reasoning-based search and retrieval of DSpace content, using Semantic Web technologies. Using a technique known as semantic profiling it allows inference-based search and knowledge discovery that would otherwise be impossible.
1.6.x, 1.7.x
Code
Dr. Dimitrios Koutsomitropoulos from University of Patras

Statistics
An add-on to the DSpace platform that allows gathering, processing and presenting usage, content and administrative statistics. While the development was done to meet the specific needs of Reposit¢riUM at the University of Minho, the system is completely adjustable to other environments as its components can easily be configured, changed or extended, to respond to different information needs.
1.4.x, hook in 1.5.2, not yet compatable with Manakin

Web of Communications
Web of communications add-on draws an interconnected network of all the items and users in the repository, highlighting their interactions at the informal level of communication (e.g. comments, downloads, deposits, etc.).

University of Minho

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.

Tombstoning
When an item is withdrawn, the user selects from 3 reasons for placing the item in tombstone: 1. Removed from view by legal order; 2. Removed from view by the [authority doing removal]; 3. Removed from view at request of the author.

Open Peer Review

One important element missing from open access repositories is a quantitative assessment of the hosted research items that will facilitate the process of selecting the most relevant and distinguished content. Common currently available metrics, such as number of visits and downloads, do not reflect the quality of a research product, which can only be assessed directly by peers offering their expert opinion together with quantitative ratings based on specific criteria.

To address the aforementioned situation, the open peer review module, OPRM, can be installed to existing Dspace institutional or other repositories and offered as an overlay service. Digital research works hosted in these repositories could then be evaluated by an unlimited number of peers that would offer not only a qualitative assessment in the form of text, but also quantitative measures that will be used to build the work’s reputation. Importantly, this evaluation system will be open and transparent.

Bibapp

University of Wisconsin Madison and University of Illinois at Urbana-Champaign

The BibApp is a Campus Research Gateway and Expert Finder. BibApp matches researchers on your campus with their publication data and mines that data to see collaborations and to find experts in research areas. With BibApp, it's easy to see what publications can be placed on the Web for greater access and impact. BibApp can push those publications directly into an institutional or other repository.

SIMILE 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.
