I need to know unambiguously where this data comes/came from. (Documentation states that Zotero does go out to the web and somehow finds this data.) That bib data may exist in the PDF file and Zotero may have spent a few seconds retieving it from the PDF file and formatting it for display, or Zotero may have retrieved it from the web somewhere, perhaps from DOI.org. General Public License and based on the open source software Freeplane and JabRef. This is its own 'bib data' as I choose to call it now. Docear is what the developers call an academic literature suite. Then seconds later much more information is displayed in the rightmost pane: Item type, Title, Authors, abstract Publication, and later in the list "DOI.org" which I assume is the source of all the above dataq. I will call this metadata since it is quite limited. containg the title, filename, #pages, modified date, Indexed indicator, and Realted and Tags. anyway, i generally would advise to let users use their own preferred pdf reader and try to make jabref work with those other PDF readers. of the popular FreeMind and the reference management is based on JabRef. if you are interested in using that add-on for JabRef, let me know. In this demonstration-paper we introduce Docear, an academic literature suite. unfortunately, the student never 100 completed the job (the new function has some bugs, but they relate mostly to Docear not the extraction of highlighted text itself). of course, that was 4 years ago and lots of things might have changed since then. we recently paid a student to enhance docear, so docear could also extract the 'real' highlighted text. every library we looked at had some serious problems or did run properly with docear.

Zotero first displays, in the rightmost pane, a 'Note' frame. we tried for a while to integrate some pdf viewer into docear, but we failed, i.e. Let me provide some more detail so we can skip the terminology barrier.
