DSpace Add-Ons

The following are descriptions of a range of DSpace add-ons available to install which provide additional functionality to the software.

The commenting feature brings informal communication capabilities to the DSpace environment. A threaded forum, or comments stream, can be attached to any web-page, community, collection, submitted item or e-person within DSpace. The add-on allows comments to be inserted by both anonymous users and authenticated ones while functionality for reviewing/moderating comments is also provided.

An example (in Portuguese) of comments appearing below a collection.

Compatible with DSpace 1.1 and 1.2 possibility of updating for DSpace 1.5.x

Controlled Vocabulary/Ontology

This add-on applies a subject classification system of the institutions choice to their DSpace instance. Once implemented the user chooses from the predefined taxonomy of keywords to describe items of information that are being submitted to the repository and that same taxonomy is used to find and access items held in the repository.

An example (in Portuguese) of a subject classification system in use.

Dublin Core Meta Toolkit

The Dublin Core Meta Toolkit gives DSpace administrators the ability to convert large amounts of information from their desktop database programs into DSpace compatible Dublin Core metadata. The toolkit provides a number of out-of-the-box database structures to ease data collection as well as enabling users to create custom converters for existing databases. The Toolkit is ideal for converting formats from Microsoft Access, MySQL and comma delimited value (CSV).

Compatible with DSpace 1.5.1


Content submitted to a repository may be restricted by laws, policies, or contractual obligations that require the submitter not to publish or enable public access to the content for a period of time.This add-on allows DSpace administrators to build in functionality to handle embargoed items in the workflow. It allows for the metadata of the embargoed item to be indexed and viewed, but the full text of the item cannot be retrieved while the embargo is in force.

Compatible with DSpace 1.4.x, 1.5.x and 1.6

Format validator and virus check

This add-on provides 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.

Compatible with DSpace 1.4.x and 1.5.x


This DSpace content-based recommendation feature automatically shows links to articles within the repository that a user is likely to be interested in by mapping items related to the document currently being visualized by the user. Similar to functionality seen on Amazon this feature can greatly improve user experience.

Compatible with DSpace 1.1 and 1.2 possibility of updating for DSpace 1.5.x

Request Copy

This add-on creates a semi-automated mechanism whereby would-be users can request and authors can email an individual copy of a full-text deposited within the repository whose full-text access privileges are set to restricted.

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.

The link is provided on all non-OA items and activates a form where the user requester must enter his/her email address and name, and may add a comment, and press a 'Request-a-copy' button. An email is sent to the depositor and the email message contains a token. Using that token, the author may reply, by just clicking in one of the two buttons available: 'Send Copy', 'Don't send copy'.

Compatible with DSpace 1.4.x and 1.5.x

Semantic Search for DSpace
Semantic Search allows intelligent search of DSpace content, using Semantic Web technologies and performs knowledge discovery on DSpace metadata. Semantic Search uses the science of meaning in language, to produce highly relevant search results.

Compatible with DSpace 1.4.2 possibility of updating for DSpace 1.5.x

This add-on allows gathering, processing and presenting usage, content and administrative statistics from the repository. The system is based on components that can easily be configured, changed or extended, to respond to different information needs.

Compatible with DSpace 1.4.x and 1.5.x (JSPUI)

The add-on allows a tombstone to be added when an item is withdrawn from the repository. The user selects from 3 reasons for withdrawing the item: 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.

Compatible with DSpace 1.4.x and 1.5.x
