I created a prototype npm package that displays a popup for selected text on a website. npm https://www.npmjs.com/package/@nakamura196/text-popup Source code https://github.com/nakamura196/text-popup Demo page https://nakamura196.github.io/text-popup/ The following article was used as a reference for development. https://zenn.dev/nino_cast/articles/98a0a87f58026f You can try it by adding the following two lines to your website. <script src="https://cdn.jsdelivr.net/npm/@nakamura196/text-popup/dist/main.min.js"></script> <script>textPopup();</script> I hope this is helpful as a reference for developing and publishing npm libraries.

Overview I had the opportunity to convert TEI/XML files to EPUB using Python, so here are my notes. While Oxygen XML Editor is one method for converting TEI/XML files to EPUB, this time I used the Python library “EbookLib.” I referenced the following article. https://dev.classmethod.jp/articles/try-create-epub-by-python-ebooklib/ In particular, this time the goal is to create a vertical-text EPUB from the TEI/XML files published in the “Koui Genji Monogatari Text Data Repository.” ...

Overview I made feature improvements to the Omeka S module “IIIF Viewers,” which configures IIIF manifest icons and multiple IIIF-compatible viewers. https://github.com/omeka-j/Omeka-S-module-IiifViewers Along with these improvements, version 1.1.0 has been released. https://github.com/omeka-j/Omeka-S-module-IiifViewers/releases/tag/1.1.0 For the release, the method described in the following article was used. The specific improvements are described below. Fixing IIIF Manifest Icon URLs As mentioned in the following article, there was a bug where the IIIF manifest icon could not be loaded into other viewers via drag and drop. This improvement fixes that bug. ...

Background IIIF (International Image Interoperability Framework) icons (specifically, IIIF manifest URLs) support loading via drag & drop in many IIIF-compatible viewers. However, I received feedback that the IIIF icons displayed by the following module did not support drag & drop. https://github.com/omeka-j/Omeka-S-module-IiifViewers I investigated the cause by referring to the following page, among others. https://zimeon.github.io/iiif-dragndrop/ As a result, I found that the following HTML markup is required. <a href="default_target?manifest=manifest_URI&canvas=canvas_URI"> <img src="iiif-dragndrop-100px.png" alt="IIIF Drag-n-drop"/> </a> Not conforming to the above pattern was the cause of the drag & drop issue in the aforementioned module. ...

I created a GitHub release script for Omeka S module development. For this development, I referenced the GitHub repository usage of Daniel-KM, who has developed numerous Omeka S modules. Specifically, GitHub repositories are created with the naming convention “Omeka-S-module-{module name}”. Example: https://github.com/Daniel-KM/Omeka-S-module-EasyInstall For releases, they are tagged with “{module name}-{version}” and a file named “{module name}-{version}.zip” is attached. Example: https://github.com/Daniel-KM/Omeka-S-module-EasyInstall/releases/tag/3.3.6 When this zip file is extracted, a folder named “{module name}” is created. This is necessary because Omeka S requires the module folder name to match the module name. ...

I had the opportunity to extract and process only text strings from XML files. For this need, I was able to achieve it with the following script. soup = BeautifulSoup(open(path,'r'), "xml") elements = soup.findChildren(text=True, recursive=True) The key point is passing text=True, which allows you to retrieve only text nodes. I hope this serves as a useful reference.

I created an API that returns a list of items containing a specified IIIF manifest in Cultural Japan. The API documentation is available at the following link. https://petstore.swagger.io/?url=https://api.cultural.jp/v3/api-docs Here is an example request. https://api.cultural.jp/v3/items/urls?manifest=https://iiif.harvardartmuseums.org/manifests/object/215190 For the API development, I used express-openapi and deployed it using AWS Lambda, referencing the following article. https://www.forcia.com/blog/002471.html I hope this serves as a useful reference for utilizing Cultural Japan.

I have created a script to batch download the modules I frequently use in Omeka S. I plan to update it gradually. I hope this serves as a helpful reference. # Module ## CustomOntology version=3.3.5.1 name=CustomOntology wget https://github.com/Daniel-KM/Omeka-S-module-$name/releases/download/$version/$name-$version.zip unzip $name-$version.zip rm $name-$version.zip ## IIIF Server version=3.6.6.7 name=IiifServer wget https://github.com/Daniel-KM/Omeka-S-module-$name/releases/download/$version/$name-$version.zip unzip $name-$version.zip rm $name-$version.zip ## Universal Viewer version=3.6.4.5 name=UniversalViewer wget https://github.com/Daniel-KM/Omeka-S-module-$name/releases/download/$version/$name-$version.zip unzip $name-$version.zip rm $name-$version.zip ## iiif viewers wget https://github.com/omeka-j/Omeka-S-module-IiifViewers/releases/download/1.1.0/IiifViewers-1.1.0.zip unzip IiifViewers-1.1.0.zip rm IiifViewers-1.1.0.zip ## easy admin wget https://github.com/Daniel-KM/Omeka-S-module-EasyAdmin/releases/download/3.3.7/EasyAdmin-3.3.7.zip unzip EasyAdmin-3.3.7.zip rm EasyAdmin-3.3.7.zip
