“JAIRO Cloud” has been provided as the shared repository service in
Japan since 2012 by National Institute of Informatics. In April 2019,
the number of institutional repositories in Japanese universities based
on JAIRO Cloud is exceeded 558, which covers 70% of the number of
institutional repositories in Japan. Nowadays, it has become to be
widely recognized as the institutional repository infrastructure in Japan.
JAIRO Cloud is built using a repository software "WEKO" developed from
scratch by National Institute of Informatics. First version of WEKO is
released in 2008. WEKO has been developed as a content management module
and is characterized by its ease of use and ease of customization. It
has been being developed while reflecting actual user voices of JAIRO Cloud.
On other hand,With the rise of the open science movement in recent
years, the content handled by repository software is becoming more
diverse and bigger than before. As a result, WEKO has been required
scalability and extensibility for supporting diversity of research data.
However, WEKO built on traditional WEB architectures, had difficulty
supporting the requirement. We needed to develop a new generation of
WEKO. Therefore, we compared major open source repository software such
as DSpace, EPrints and Fedora and chose Invenio version 3 for our
purpose and started development of new version of WEKO(hereinafter
In this presentation, we will briefly introduce our background, and
introduce the functions, features, problems, and future plans of WEKO3
