National Institute of Informatics - Digital Silk Road Project
Today we added two important functionalities into this site.
The first is high resolution image browsing using IIIF. IIIF (International Image Interoprability Framework) is a standard widely used for image access (delivery), whose advantage is in easier setup for high resolution image delivery using IIIF-compliant image servers and image browsing software. Since the opening of this website in 2004, this website has been restricting access to low resolution images with around 900 pixels, but we decided to provide high resolution images with around several thousand pixels in order to follow up the global trend of delivering higher resolution images. High resolution images allow users to see the detail of images, thereby will promote the usage of images for research. In addition, this site uses IIIF Curation Viewer, which has a new functionality such as curation, and we plan to expand our research by taking advantage of such new functionality. Please note that Fourth CODH Seminar: A New Trend on Image Delivery in Digital Archives - IIIF's Potential for Standardization and Sophistication of Image Access - summarizes background information about how IIIF adoption is expanding now.
The second is the assignment of DOI for permanent identifiers. DOI (Digital Object Identifier) is a system to identify uniquely the access path to the resource (material), and sharing of identifiers across various resources has advantage such as the standardization of citation and visualization of evaluation. For this purpose, we started Humanities Research Data Repository on JAIRO Cloud, a repository system operated by NII, and by registering metadata of 134 materials and obtaining their DOIs, we organized a system to support permanent access by DOIs. Please note that Third CODH Seminar: Usage of DOI for Humanities - Assignment of DOI for Scholarly Resources such as Research Data and Museum Collections - summarizes background information about the impact and challenges of DOI for humanities data.
We believe that the adoption of IIIF and DOI for image delivery will become the standard system for humanities research archives. We plan to extend this mechanism to other types of digital archives.
