Gerd,
regarding your question about how to import data in OpenCms.
There are multiple ways to import data to OpenCms, e.g.:
* OpenCms native XML based import
* Local file synchronization
* CMIS access to VFS
* WebDav access to VFS
* Network share access to VFS
Of these, the network share access is certainly the most modern and powerful option.
How to set this up is documented here:
http://documentation.opencms.org/opencms-documentation/more-opencms-features/mounting-the-vfs/network-share-access/index.html <http://documentation.opencms.org/opencms-documentation/more-opencms-features/mounting-the-vfs/network-share-access/index.html>
Once you have this working, your can access the OpenCms VFS like it is part of the native file system of your server.
You could then export your content form your old CMS, process in on the shell level, and just copy the transformed XLM to OpenCms also via shell commands.
Kind regards,
Alex.

>> Dear List,

>> a short introduction:
>> after about 10 years of intensive develop and maintenance work for a large website + mobile and some smaller (still productive) with the Open Source CMS "Apache Lenya" (and Cocoon 2.1) I re-discovered OpenCms (used it about 13 yrs ago for some smaller sites) as a potential replacement for Lenya.

>> To kind of "finalize" my prototype and show it to the customer I need to fill it with content (about 1.500 documents, each html in 3 langs + a PDF per doc)).
>>
>> With a small amount of testpages (6 folder + 5 docs + 5 PDFs) I tried the Extended HTML Importer.
>> After adding "head|Head Element,body|Body Element,foot|Foot Element" to the template's "template-elements" property (found this hint somewhere in the I-net) the import run was successfull w/o errors.

>> - no edit option in the page editor available

>> - in EXPLORER I can't navigate to the imported data; when expanding the parent folder (subfolder in my prototype site) the arrow in front of the the folder icon rotates to point downward but nothing happens; on hover (over the folder) a kind of tooltip shows in red an Exception.
