P2B: Image Management
Mirador: A Cross-Repository Image Comparison and Annotation Platform
Stanford University, United States of America
The Mirador viewer embodies the promise of Open Repositories from which content may be accessed on the web by any system, rather than only by the repository's own user-facing client. In an ecosystem of truly open repositories, which host open access content and are built on common infrastructure and common APIs, Mirador enables new forms of scholarship and publication by bringing disparate content together in a single image viewing platform. As cultural heritage organizations move towards openly sharing content of all types from their repositories, web applications like Mirador can easily enable comparison, analysis and innovation across repository boundaries.
Crowdsourcing of image metadata: Say what you see
1University of Edinburgh, United Kingdom; 2Dartmouth College, United States of America
Digitised archival, museum, gallery and library content often lack metadata on the subjects within the image as the only metadata is for the source object. For example, the name of the author of the digitised book is known, but not that the image shows a bird. Crowdsourcing games allow this missing data to be captured through mass-participation with users describing what they can see. The integration of user-generated tags aids discovery of cultural heritage collections through the enhanced search terms provided.
Tiltfactor Laboratory at Dartmouth College has developed Metadata Games http://www.metadatagames.org as an online platform for gathering user-generated tags on photo, audio, and video collections. In tandem, the University of Edinburgh has developed its own crowdsourcing game to improve discoverability of its collections.
This presentation will discuss our experiences with crowdsourcing games including challenges encountered and workflows for integrating user-generated/folksonomic tags with authoritative data to aid discovery. Preliminary data will be presented illustrating the extent that user-generated tags enhance search at one’s institution and increase traffic to online collections.
Finally, there will be information on how you can use metadata games to enhance the discoverability of your institution's collections.
Authenticated Access to Distributed Image Repositories
1Stanford University; 2Princeon University; 3Cornell University; 4Yale University
An increasing percentage of the world's cultural heritage is online and available in the form of digital images, served from open repositories hosted by memory, research and commercial organizations. However, access to the digital surrogates may be complicated by a number of factors: there may be paywalls that serve to sustain the host institution, copyright concerns, curatorial arrangements with donors, or other constraints that necessitate restrictions on access to high quality images. Images are also often the carrier for scientific and research information, particularly in the medical and biological domains. In many of these cases the images cannot be openly available because of personal privacy.
The International Image Interoperability Framework (IIIF) has made great strides in bringing the world's image repositories together around a common technical framework. Now with its membership boasting nine national libraries, many top tier research institutions, national and international cultural heritage aggregators, plus commercial companies and other projects, use cases such as those above have raised authentication and authorization to the top of the “must-have” list of features to ensure continued rapid adoption. This presentation will focus on description of the IIIF authentication use cases and challenges, and then outline and demonstrate the proposed solution.
