Manage pdf metadata?

[Toneti777]

I'm thinking about try to read and convert some metadata information of pdf file to html accessible "elements".
This metadata would be external links or why not.. embedded videos.
I don't know if you have thought about this or it is planned for future. I think that it would be a very good improvement.

Thanks a lot, and good job.

In very early version of pdf2htmlEX, some metadata (e.g. title, author) are retrieved, I wanted to extract title and put it as the title of HTML. However I found that that piece of info of lots of PDF generated from LaTeX were inaccurate, due to the intermediate conversions (tex -> dvi -> ps -> pdf). So I dropped those code.

It's not hard to extract those information, but I'm not sure what's the proper way of storing them into HTML. I'm almost sure that I should use <meta> tag, but not sure about the property names.

@coolwanglu MDN has quite a nice list of property names that would be appropriate in this situation.

If you point me out to the code that extracts the metadata I would like to work on putting them into HTML.

@mrshu It's something like this: https://github.com/coolwanglu/pdf2htmlEX/blob/paperclub/src/PaperClub.h#L146 but maybe you need to read poppler code and PDF spec for complete keys.

Hi, Toneti.
Thanks for sharing your problem. I wonder have you found your way out? When it comes to pdf text extraction processing, I wonder whether text extraction from pdf files is much simpler than pdf to text conversion process. There's something wrong with my pdf viewer. I want to look for a method to help with the relevant process. Any suggestion will be appreciated. Thanks in advance.

Best regards,
