The digital curation lifecycle
Digital curation is the management andpreservation of digital data/information over thelong-term.
Digital curation involves maintaining, preservingand adding value to digital research data
throughout its lifecycle.

Japan Search
A platform that collaborates with digital archives
from various fields such as books, culturalproperties, and media arts, allowing for theunified search, viewing, and utilization of
metadata for the diverse content held by ourcountry.

Cultural Japan
Japan Search allows to search data
published by institutions mainly inJapan. It is still difficult to discover dataon Japanese culture that is held andpublished by institutions outside ofJapan.
↓Develop a system for collecting data on
Japanese culture published byinstitutions worldwide and enhancing
their discoverability

OmekaOmeka is a free and open-source content
management system for online digitalcollections: A rich array of modules related toDigital Humanities (DH), such as Linked Data,IIIF, Scripto, OAI-PMH, etc.
In the field of digital archives in Japan, theadoption of OSS has not progressed much. In
response to this challenge, we publish tutorial
articles on how to use OSS, such as Omeka.

Digital Preservation
Expanding the foundation for long-term digital
data preservation in Japan is essential forenhancing research data management.
Archivematica is a valuable tool for digital data
preservation but requires IT skills due to its
comprehensive features.
To mitigate these barriers, we developed anapplication that simplifies the process of digital
data transfer and AIP creation is necessary.

It is a common understanding among
paleography and Japanese
historiography that the position andsize of the Kao (Stylized Signature)are important information.
One of the challenges is that, notenough objective data has beenpresented for such a commonunderstanding.
This study analyzes the location andsize of Kao quantitatively. Data isexplored using numericalsummarization and visualization
through exploratory data analysis.

Digital Tale of Genji
By collecting and creating various
types of data relating to the Tale ofGenji, and linking them to the text
using IIIF, TEI, and AI technology, thissystem aims to provide anenvironment to assist Tale of Genji
research, as well as education andresearch activities using classicaldocuments.
