extract or export annotation or highlight from personal PDF kindle

Hello there.

I am using the kindle to read scientific papers and do a lot of highlights. I intended to use Calibre and the annotations plugin for retrieval of those. I recently realized that highlights in personal pdf files are neither saved to the Myclippings.txt file nor can they be uploaded or bulk shared to my local amazon account (I would prefer a calibre solution anyway).
Every python and java script I found would do the same, extract the myClippings.txt.
However, it seems that the notes and highlights for personal pdfs are saved as pointers (i hope this is the right expression ?) in the .str folder in a .pds or .pdt binary file. Those however are a complete enigma to me.
Does anyone know if it is possible to extract the information with calibre?

The only solution that I could come up with so far would be setting up a facebook account and sharing each highlight individually (= tapping on each highlighted line in each book on the paperwhite) and then try to retrieve all posts from that account with some APU. ... rather discouraging.
Any idea or help would be greatly appreciated.

Basically someone would need to reverse engineer those binary formats.

Ok , I guess that is not a trivial task. And the Amazon people probably do not have an interest in helping. Thank you anyway, I guess I have to keep to sharing my notes on facebook or twitter to extract them. Maybe I should try to convert the pdf to an ebook format in the future, but for formulas , figures and formatting I don t think it works very well. (At least it did not last time I tried).

PS: Thanks for the great tool (Calibre). I wish something as thought through and open would exist for science paper-management.

@jonie: I maintain the Annotations plugin. For Kindles, this reads the My Clippings.txt file and put this into a column in calibre for the books. I haven't heard that annotations for PDFs are not in the My Clippings.txt file. That might just mean that the people who use PDFs already know that they don't appear there. I'm not a Kindle user, so I can't test myself.

Kindle does store the annotations in other files. From a little looking a while ago, this would be a better place to get the annotations from. But, either the format isn't known or it encrypted somehow. I can't remember off the top of my head, but my memory was that it wasn't practical to use for this purpose.

@davidfor: at least if you do not send the pdf via amazon email they don't. Probably most people convert pdf anyway and researchers jprobably still just print their articles . I think they use different formats on different kindles and as kovidgoyal said they would have to be reverse engineered.

I found some code that tries the reverse engineering but it dates from 2011 and is for .pdr which is not the format used on my paperwhite.
