So I have downloaded Ephesoft Community 4.0.2.0 (http://wiki.ephesoft.com/community-edition-v4-0-2-0) and successfully installed it on a virtual machine running Ubuntu 14.04.
The program itself functions like just fine. I can make document classifications and import/export all I want. The only point is that in my configuration I seem to be missing a lot of plugins. Plugins that should be there out-of-the-box as the documentation mentioned. The foremost missing is the CMIS plugin for both export and import. I have found numerous tutorials on how to communicate with Alfresco and others so that is now what I need. I would like to know what I am missing.
BTW: I am aware that the table on the download page states that they are not supported, but that doesn't make them missing, right?
[EDIT] I have also found the google code dcma-data-access link, but that does not seem to help either.
Through the live-chat with Ephesoft I found out that it is impossible to install any plugins for the Ephesoft Community version. Not supported literally means "can't be installed".
That pretty much answered my question.
