I recently finished work on CommonsTool, a Python script to upload artwork images to Wikimedia Commons. In addition to uploading the image files, it creates Structured Data on Commons claims to provide machine-readable metadata about the images and to link them to Wikidata items that describe the underlying artwork objects. It also uploads the images to the Vanderbilt Libraries’ International Image Interoperability Framework (IIIF) server and generates IIIF manifests to display those images in a IIIF viewer.
