Overview Omeka S uses RDF (Resource Description Framework) to describe information about resources (items, item sets, media, etc.). Therefore, it is necessary to import vocabularies, which are collections of RDF classes and properties. This article explains how to import existing vocabularies. The official manual is available at: omeka.org Specifically, we will use the following as examples: the National Diet Library Dublin Core Metadata Description (DC-NDL) provided by the National Diet Library, Schema.org, and the Japan Search Utilization Schema. ...

You can view the IIIF Collection that aggregates the IIIF manifests gathered by Cultural Japan at the following link: https://www.kanzaki.com/works/2016/pub/image-annotator?u=https://app.cultural.jp/iiif-collection/collection.json Please check the terms of use for each source database when using the individual IIIF manifests. This collection includes IIIF manifests dynamically generated by Cultural Japan. In the collection list above, these can be identified by the label “Dynamically Generated.” The dynamic generation uses AWS Lambda, querying the Japan Search RDF Store and the Cultural Japan RDF Store for each request to generate JSON data. The condition for creating these dynamically generated IIIF manifests is that the items must have high-resolution images (jps:accessInfo/schema:associatedMedia). ...

We created a repository demonstrating how to use Mirador 3 with Vue. We hope it serves as a useful reference for application development with Vue. github.com This repository was created with reference to the following: github.com As a simpler alternative, you can also use the UMD (Universal Module Definition) build. If you simply want to use Mirador 3, we recommend the following approach: github.com The site above states (as demonstrated in the repository introduced here): ...

I hope this feature contributes to improving the sustainability and usability of digital archive systems. Background The Omeka S IIIF Server module generates IIIF manifest files from metadata registered in Omeka S. It is primarily developed by Daniel-KM, who has developed various Omeka modules. ...

Overview I implemented a IIIF representation of “Okoshi-ezu” (raised picture maps). The target materials are the Okoshi-ezu contained in the “Dai Nihon Kaishi Compilation Materials” held at the University of Tokyo Komaba Library. https://utda.github.io/kaishi/ Please watch the following video for an overview. “Okoshi-ezu” IIIF Implementation The Application The following is the Tokyo National Museum’s description of “Okoshi-ezu”: “Okoshi-ezu” are foldable simplified models that reproduce the three-dimensional structure of buildings by pasting wall and ceiling diagrams onto a flat plan drawing. They were particularly used as a drawing technique suited for reproducing tea rooms, which have complex three-dimensional structures within small spaces. (From the Tokyo National Museum - Japanese Art (Honkan) Japanese Natural History Series: Okoshi-ezu) ...

Overview I created a “IIIF Application Using Transmitted Light Images.” It focuses on the “Shelley Correspondence” held at the University of Tokyo General Library. utda.github.io The Application This application uses IIIF’s “Choice of Alternative Resources” to provide an environment for comparing original images with transmitted light images. Four comparison methods are provided, using “IMAGE COMPARISON WITH A SLIDER,” “MIRADOR,” “IIIF CURATION VIEWER,” and “IMAGE ANNOTATOR.” IMAGE COMPARISON WITH A SLIDER This uses the image comparison viewer developed by Digirati. You can compare images by moving the slider in the center of the screen. ...
