Documentation for metadata extraction

[jcoyne]

Docling lists "Metadata extraction, including title, authors, references & language" as a feature, however I don't see anything in the documentation about how one gets these values out.

I've tried:

docling --to json https://assets-eu.researchsquare.com/files/rs-66715/v1/2c370dd5-7279-4a77-89dc-94297f0a7843.pdf\?c\=1637243468

and

docling --to json https://arxiv.org/pdf/1904.09664

But it doesn't seem to find any metadata. Am I using it correctly?

How to get the metadata info like title, authors, references & language ?

@jcoyne @ujjawal-ti Hi all, we had some initial meta-data extraction capabilities in docling-v1, but we the inclusion of the other formats (HTML, DOCX, etc) in docling-v2, we had to temporarily disable meta-data extraction.

We plan this functionality to be back in future releases. Which meta-data are you mostly interested in?
