Post docear- (RC for public beta7)

There is a bug which prevents some of our users to select any pdf reader.
We will release a fixed version in a new thread soon.

Thanks for your help with testing Docear!


Hello Docear community,

it nearly took us two months to create this latest experimental version of Docear. That's a lot and we were definitely NOT lazy. 🙂
I think the beta7 version of Docear introduces a very important feature for all researchers using our software. Finally me made it work and are proud to present:

The PDF Metadata Extraction

This feature enables you to automatically generate entries in Docear's integrated reference manager based on the pdf file you are using.

If you have a mind map node with one of your research papers attached, just drag&drop the pdf file to the reference manager's panel and a dialog will appear asking you whether you want to create a new existing entry, or update an existing entry based on the data fetched from the Docear services.

As you might recall, it has been possible previously to retrieve meta data in Docear, but the data was coming from Mr Dlib. However, this process was very very slow because the entire PDF was sent to Mr DLib where it was analyzed. In addition, the metadata-database of Mr Dlib was rather small.
Our own and new function is much faster and we have much more data in our own digital library, so chances are really high, that you get some good results! 🙂

It works like this:
A dialog will open showing the automatically extracted title of the paper. The extraction algorithm is still very simple but it already works pretty well. If the extracted title is not correct or if the authors or a subtitle is included in the extracted string, please manually fix it.
After confirming a request will be send to our digital library and the reference will be returned.

Please keep in mind: In order to use this service a request with the title will be send to our web service. This is currently only possible if you register yourself with the Docear services!
The necessary settings are accessible through "Tools">"Preferences ...">"Online Services">"Manage Docear service settings...").

And one more important information: each user is limited to 15 requests a day. This is for testing purposes and we are hoping to being able to raise this limit soon.

Other new features

  • We now include a link to an explanation on how to resolve the annoying duplicates issue which happens in BibTeX files extracted from Mendeley.
  • If you have any problems regarding the PDF-XChange-Viewer, you can extract and send it's settings to us for bug fixing. We hope that this will help us to further improve Docear's support for this very usefull tool.

Unfortunately we also have some bad news at least for our MacOS users:
We found out that both Preview and Skim on MacOS change the object numbers of annotations on save attempts, although the pdf 1.7 specification ( states on page 63:

"Together, the combination of an object number and a generation number
uniquely identifies an indirect object. The object retains the same object number
and generation number throughout its existence, even if its value is modified."

We are very unhappy about it, but we had no other option than to deactivate our support for both tools, since this means that we can't synchronize any annotations from or to the PDF files without running into a lot of conflicts, duplicates and other unwanted effects.
For now, the only pdf reader on MacOSX we know of, which supports pdf annotation and sticks to the PDF standard is the Acrobat reader.
If you have any suggestions on how to get the PDF-XChange Viewer running on MacOS (maybe using PlayOnMac) or if you know about another reader, please don't hesitate and tell us about it!
