Hello, I am Stefan of the Docear team.

What we are currently doing is to read comments and bookmarks created in PDF
files using the JPod library (http://sourceforge.net/projects/jpodlib/) and
export them from the PDF files and attach them to nodes in mind maps.

The nodes then contain information on 
- the link to the PDF file,
- the page the annotation was extracted from,
- and the annotation's object number. 

By clicking the link icon on a node, the PDF viewer will open up on the page
containing the annotation. This is especially very useful for researchers, who
are typically reading a lot of scientific documents every day and need to keep
track of both the ideas and facts in general and the location where they have
found them.

Docear (http://www.docear.org) is an open source (GPL v2) project based on
Java. It is available for MS Windows, MacOS and Linux or UNIX. I am using
Debian (the unstable "sid" branch as my default operating system. Unfortunately
I do not know a single PDF viewer for Linux which can do the following:
- easily create notes and bookmarks in PDF files (like e.g. the Foxit reader,
Adobe Acrobat or the PDF X-Change viewer available for MS Windows) and edit
annotations created by these tools
- store the PDF files preferably incrementally (i.e. keep the annotation's
object numbers the same over all saved revisions of the PDF file --> this might
not be needed for future versions of Docear)
- automatically copy the contents of highlighted text into a "note annotation",
so that Docear can read it and the user can modify it, e.g. by adding
additional data or explanations. (This is a very useful feature in the PDF
X-Change viewer)
- and open a PDF file at the location of a specific annotation, e.g. by passing
the annotation's object number to the PDF viewer (Okular can open a PDF file on
a specific page, which is not optimal for our use case, but nevertheless very
useful) 

Is there a way to implement these features into Okular? On Linux systems we are
currently using either the Foxit reader or the PDF X-Change viewer from WINE,
which is obviously not the way it should be done.

Docear is still a very new project, but it is used by several thousand
researchers in their daily work just now. Any help you can provide is very much
appreciated.

Thanks for your time and best regards,
   Stefan
