5. Alamire project Alamire =
International Centre for the Study of Music in the Low Countries
Digitize medieval music manuscripts at high resolution ( million pixels) for research
Integrated Database for Early Music (IDEM) project requirements:
Data model and query options
Collaboration with other researchers
Long term preservation of content
High resolution viewer!

6. This influenced the selection of tools
Alamire project
Proposal prepared in collaboration with LIBIS (Flemish Hercules infrastructure call, September 2013)
Kick-off summer 2014, launch of IDEM summer 2015
Project funding:
Main budget preserved for storage & long term preservation
Limited resources for database, website, and viewer
Currently no budget for post-project maintenance
This influenced the selection of tools

7. CollectiveAccess, Omeka, Rosetta, IIIF Mirador viewer
Decision to:
Reuse a combination of existing tools in a flexible way
Use open source where possible to limit the license costs
Share development costs with projects with similar interests

Limitations and what they can expect
Open source doesn’t means free

8. Visualization requirements
Giving access to high resolution images in a novel way
Quick, without loss of quality (JPEG2000)
Easy navigation within manuscript
Full screen, tool bars should take up limited space
Extensive zooming options in a single and fluid movement, focused on selected area
Compare folio’s from different manuscripts in a single view
Illegal download protection, watermarks
...

9. Selection of IIIF Mirador viewer
Virtual Vellum prototype image viewer suggested by Alamire
Developed by University of Sheffield
Issues: no updates since 2008, Java development
Suggestion by LIBIS to use IIIF/Mirador instead
Some remarks on demo version tested by Alamire (v ,
Mayor:
Endless pop-ups

The IIIF (International Image Interoperability Framework) is a collaboration between world leading digital libraries and heritage collections in an attempt to create a common framework enabling the digital collections to exist in a single environment.
Basic princiCommunity driven, defined API’s, Plug & Play software

15. The IIPImage server is a feature-rich high performance imaging server engineered to be stable, fast and lightweight. It is designed for streaming extremely high resolution images and is capable of handling advanced image features such as 16 and 32 bit depths, floating point data, CIELAB colorimetric images and scientific imagery such as multispectral or hyperspectral images.
Mirador:
Mirador is an open source image, Javascript and HTML5 viewer that delivers high resolution images in a workspace that enables comparison of multiple images from multiple repositories, available as manifest.json files, gathered in the index.html file
Fully supports IIIF Presentation API
Uses the Image API syntax to get images of the IIPServer.
IGeLU Tools for Digital Humanities

16. Image API
This specification concerns image requests by a client, but not management of the images by the server. It covers how to respond to the requests given in a particular URI syntax
Example url
Applications
Digital image repositories and distributed content networks.
Image focused web applications, such as pan/zoom viewers, book readers, etc.
Client applications using image content for analysis or comparison.
IGeLU Tools for Digital Humanities

17. IIPImage Server
Fully supports delivery of images via URLs as specified in the IIIF Image API
Open source fast cgi server (written in C++-) runs under apache
Supports JPEG2000 , pyramid TIFFs.
IGeLU Tools for Digital Humanities

18. Presentation API Objectives and scope
Provide the information necessary to allow a rich, online viewing environment for primarily image-based objects to be presented to a human user, likely in conjunction with the IIIF ImageAPI
Use of JSON-LD format or JavaScript Object Notation for Linked Data
A lightweight Linked Data format. It is easy for humans to read and write.
IGeLU Tools for Digital Humanities

19. Primary Resource Types
Basic JSON LD syntax elements, in hierarchical order:
Manifest
The overall description of the structure and properties of the digital representation of an object.
Sequence
The order of the views of a physical object.
Canvas
A virtual container that represents a page or view and has content resources associated with it or with parts of it.
Content
Content resources such as images or texts that are associated with a canvas.

20. Viewer plugin for Rosetta
A java VPP jar plugin, which
Creates the manifest files per entity dynamically.
Afterwards creates an html file which collects all the entity manifest files of one entity type,

35. Future plans with IIIF & Mirador
Implementation of access rights control
Implement IIPImage server more widely to create manifestation and watermarks on the fly instead during ingest
Simultaneous view of image, transcriptions and annotations (by getting metadata out of Rosetta web service)
Adding multispectral view support to Mirador (e.g. IIPMooViewer)
