Maybe I create some script with "python" to glue all mentioned applications. But I am now searching whether there is a more simple and straight-forward solution.
No, doing this with Zope so it's really useful demands you to "glue" together not the applications, but the API's. You need the minimum of functionality that when you upload a scanned image it OCR's it and indexes the text for searching. It's not hard to do if you know how to develop for Zope and have an OCR API. But knowing how to develop for Zope is a big hurdle.
I have been running PaperPort/PageKeeper/OmniPage/Pagis for years. They work fine on Windows. But I am searching for a similar application from OpenSource to run on Linux
Well, Zope is not that application. Zope is rather a development platform where you can DEVELOP such an application, but unless you need it to be web-based, it's probably not the right platform. If you need it to be web-based it's an excellent platform, but you still need Zope development skills.
