Who I am?

Andrea Bollini, 4Science - IIIF Annual Meeting 2017

http://www.4science.it/en/

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



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



Easy to use and maintain (cost effective)

Accurate description (metadata)

High web visibility (SEO)

Suitable for self-archiving or proxy archiving

Validation and approval workflow

Digital preservation (OAIS compliant & integrations)

Persistent Identifiers, Versioning

Interoperability (OAI-PMH, SWORD, REST, etc.)

DSpace: key characteristics



4Science IIIF Image Viewer Addon

IIIF Compliant

1. Presentation API

2. Image API

3. Search API

4. Authentication API (soon)

DSpace item with “see online option”


Offering an integrated

Universal Viewer

player


IIIF Image API

allows a smooth

interaction with the

image files



IIIF Presentation API

generated on the fly using

the metadata of the item

and the bitstreams



Bitstreams

metadata

Hierarchical

ToC

An example from a PDF

document offered as a

complex package of

page-image



Link images with their textual

transcription / OCR

Indexing standard format (hOCR) in a

webannotation server to supply IIIF Search API



Side by side – image vs text using an additional

OCR panel



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.)

Limit max allowed resolution for anonymous users, normal users,

special users

Link with ecommerce solution for print, HQ copies

Integration with collaborative transcription platform

Other features



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 Image Viewer):

- 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

http://www.4science.it/en/dspace-add-ons/

We have joined the Universal Viewer 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
