How to attach metadata (reference/biblio) info to a quote from a pdf

Hi all, new here, apologies, already searched the forum for a previous such question,

in reading a pdf book or research paper that I have legally downloaded as a uni student (for a standard lit. review, paper/article, whatever, that I am writing), I would like to be able to highlight (or otherwise select and copy) a piece of text from the pdf file and subsequently copy it to a word processor application, but - here's the thing, -- I need to have certain metadata attached to the actual quote that I've just taken, so that I can subsequently easily identify this quote in the "bibliography" or "references" section of my paper.

ideally, this is done by an app, though so far, I haven't been able to find one, none of the pdf readers/markup software seems to go this far,

can anyone tell me whether, when a section of text is lifted from a pdf file, whether there is any metadata that is, or could be, assigned/attached to this piece of text (now on a clipboard), so that it is carried, more-or-less for ever, with the quote taken?

this metadata would include the usual biblio/reference stuff, such as Author, Article/Book Title, Date of Pub., Publisher, etc.

note that I am aware that an entire pdf file has/can have metadata attached to it, but I am needing to have such info attached to a piece of text that I copy from it, not just the entire file itself . . .

thanks!
