[Omeka S Module Introduction] Custom Vocab

Overview I introduce Custom Vocab, one of the Omeka S modules. https://omeka.org/s/modules/CustomVocab Below is my translation of the description from the official site. The Custom Vocab module allows you to create controlled vocabularies and add them to specific properties in resource templates. When using that template for items, properties are loaded as dropdown menus limited to the controlled vocabulary options, instead of text input boxes. For example, you can create an institution-specific list of locations corresponding to various collections on campus, or a controlled list of people or places related to holdings. This can reduce typos and name variations, and provide metadata references for more fields. ...

Dealing with AttributeError in ultralytics/yolov5

When using ultralytics/yolov5, the following error occurred. AttributeError: 'Detections' object has no attribute 'imgs' As mentioned in the following issue, this appears to be caused by an API change. https://github.com/robmarkcole/yolov5-flask/issues/23 As one example, the error was resolved by rewriting the program as follows. results = model(im) # inference # new def getImage(results): output_dir = "static" if os.path.exists(output_dir): shutil.rmtree(output_dir) results.save(save_dir=f"{output_dir}/") return Image.open(f"{output_dir}/image0.jpg") # old def oldGetImage(results): results.render() return Image.fromarray(results.imgs[0]) renderedImg = getImage(results) I hope this is helpful for those experiencing the same issue. ...

An Example of Manipulating JSON Files with Nuxt 3's server/api

This is an example of how to manipulate (import and use) JSON files with Nuxt 3’s server/api. The following article was used as a reference. https://github.com/nuxt/framework/discussions/775#discussioncomment-1470136 While there is much room for improvement in areas such as type definitions, the following approach was confirmed to work. // async/await を使用しています。 export default defineEventHandler(async (event) => { const items_: any = await import('~/assets/index.json') // .defaultをつける点に注意 const items_total: any[] = items_.default // 以下の参考リンクを参照してください。 const query = getQuery(event) const page: number = Number(query.page) || 1; const size: number = Number(query.size) || 20; const items: any[] = items_total.slice((page - 1) * size, page * size); return { "hits": { "total": { "value": items_total.length, }, "hits": items } } }); With the above, by using a query like /api/items?page=2&size=40, it was possible to return a portion of the imported JSON file (~/assets/index.json). Paths other than assets seem to work as well, but this has not been thoroughly verified. ...

Supporting Drag & Drop for IIIF Icons

Background IIIF (International Image Interoperability Framework) icons (specifically, IIIF manifest URLs) support loading via drag & drop in many IIIF-compatible viewers.

Creating a GitHub Release Script for Omeka S Module Development

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.

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. ...
