You can add metadata dynamically from the document:

For example, if the document is:
\`\`\`jsonl
{
    "source": "www.example.com", "content": "Hello World!"
}
{
    "source": "www.example2.com", "content": "Hi World!"
}
\`\`\`

You can have the "source" value as metadata by returning the following:
\`\`\`json
{
    "source": "/source"
}
\`\`\``;
