Do It Yourself History

The diy subcommand retrieves images and transcriptions from collections available on the DIY History website.

Publish to Arkindex

The publish subcommand publishes local JSON files scraped by other subcommands to an Arkindex instance. Any JSON file is supported, provided that they respect the following format:

{
    "name": "", // Name of the element on Arkindex
    "metadata": [ // List of metadata to publish on the element
        {
            "type": "", // Arkindex type of the metadata
            "name": "", // Name of the metadata
            "value": "" // Value of the metadata
        },
        ...
    ],
    "items": [ // Elements published as children
        {
            "name": "", // Name of the element on Arkindex
            "metadata": [], // List of metadata to publish on the element
            "transcriptions": [ // List of transcriptions to publish on the element
                "", // Text of a transcription
