DSpace is the world-leading open-source repository platform with more than 2200 installations. DSpace allows easy management of digital assets, with web UIs to upload, describe and access content. 4Science added IIIF capabilities to DSpace, through a dedicated add-on, so that images and image collections can be accessed and shared with a IIIF viewer. Out-of-box, an enhanced version of the Universal Viewer client is integrated, providing smooth access to the images archived in DSpace. The add-on can embed any IIIF Image API servers such as Digilib, IIPImage, etc. and implements the IIIF Image API, IIIF Presentation API, IIIF Search API. The DSpace DRM policies defined for the single image or collection (open access, embargo, reserved access) are enforced in the IIIF player. DSpace has also be enriched with other relevant modules such as a PDF viewer, OCR, audio/video streaming.

3. Many projects struggle creating IIIF Manifest with
manual or semi-automatic process…difficult to update,
improve, maintain; lack of additional features: LTP,
authNZ
Some specialized software can help but they work only
on digitalized content or images making them another
data silos…
IRs are already in place, no additional costs to adopt
them also for images collections
Why use the Institutional Repository

4. DSpace
Open source solution (BSD 3-Clause license)
Community driven
- Committers group (Technology)
- Steering committee (Strategy)
Under the umbrella of the Duraspace Foundation
The most used repository platform in the World (more
2200 known installations)
DSpace-CRIS is an extension of DSpace available with
the same license featured for Research Management

14. Access to the original file is controlled by DSpace
Can use any IIIF compliant image server (tested with Digilib,
Cantaloupe, IIPImage) – security enforced by DSpace
Preprocessing of NEF, CR2 raw formats or PDF file to use with
the image server – using DSpace curation tasks
Integration with OCR Engine (Tesseract, Abby, etc.)

special users
Link with ecommerce solution for print, HQ copies
Integration with collaborative transcription platform

15. An innovative Open Business Model
#makeITopen http://www.4science.it/en/dspace-add-ons/
Our Addons is proposed to partner Institutions for a small contribution
to cover our investment in R&D.
Once the target is reached the addons will be released as open source
for the whole community
All in a transparent way (example for the IIIF ImageViewer):
- Single contribution to access and use the code €5,000
- Adopters listed on the website
- €150K to release (BSD-3) the current code and the planned roadmap

16. We have joined the UniversalViewer conversation on GitHub
proposing a new panel to visualize text side-by-side with the
image (OCR Panel: PR#424)
We are using the DBMDZ IIIF Presentation JAVA API library
contributing back our findings (better support for 2.1)
We are advocating pro-IIIF
- in the Repository communities proposing it as a suitable technology for
knowledge sharing and reuse. It is our recommendation for the NGR COAR
TG
- in the CRIS /VRE community proposing it as the standard to deal with
research images
How we collaborate with the IIIF community
