Metadata Lab (Knowledge Sharing Infrastructure Research Group)
Machine-translated · View original
A lab that uses metadata to manage and preserve information resources on the internet.
AboutAbout the lab
Attaching metadata that stays understandable 100 years from now.
The Metadata Lab works on research using metadata in order to distribute and manage the wide variety of information resources on the internet.
Metadata is "data about data," and the lab's website explains it by comparing it to the label on a can.
The lab aims to attach metadata to digital content so that its contents remain understandable one year, ten years, and 100 years from now, making access and management easy.
The lab welcomes students who are interested in the idea of "getting hands-on and making something!" Students who want to be assigned to the lab must have an interview with a faculty member.

The lab studies technologies and methods for attaching metadata to information resources on the internet to support their distribution and management. Its themes cover digital archives, manga, Linked Open Data, and metadata schemas.
*Illustrative imageDigital archives
To preserve and provide content over the long term, the lab studies the design and management of metadata, support for discovering preserved content, and linking of multiple archives. Its targets include archives related to the Great East Japan Earthquake and intangible cultural heritage.
*Illustrative imageManga metadata
The lab builds metadata that describes the content of manga, structures such as panels and characters, and relationships between manga and with other materials, in order to support digital activities related to manga. It also studies how to create metadata efficiently.
*Illustrative imageUsing Linked Open Data
The lab studies attempts to make metadata from various people and organizations usable in combination on the Web. It works on discovering metadata that can be linked, supporting the construction of systems that use it, and linking metadata for manga, anime, and game works.
*Illustrative imageSupport for creating metadata schemas
To create schemas, which are the blueprints for metadata, efficiently, the lab works on supporting the creation of new schemas by citing and adapting existing ones. It is also involved in developing a registry in which schemas can be stored and searched.
