ox-publish: Some starting problems

[c.buhtz@posteo.jp]

Hello together,

I was able to generate HTML files of my org-roam (v2) nodes. But I have 
some problems and need to be pointed into the right direction.

1.
Is this mailing list the right place to discuss ox-publish related 
topics? The ox-publish.el only contains two e-mail addresses?

2.
Because ox-publish is skipping "unmodified files" I deleted all HTML 
files between the publish-runs just to be sure that there are no side 
effects. But now when my output directory is totally empty ox-publish 
still keeps saying that it is skipping the unmodified files. So nothing 
is generated anymore. How can I handle that? Maybe resetting the 
"unmodified" flag somewhere? Or shouldn't ox-publish not only check for 
modifications but if there is something earlier generated content exist?

3.
I use (setq org-export-with-broken-links t) with and without 
":with-broken-links "mark"" to prevend ox-publish stopping when there 
are broken links. I swear and I also checked that there are only a few 
of them. But in the HTML output all links are gone. No links. No text 
for the links.
I tried to reproduce this in a minimal example with two new nodes. But 
for them the links are generated.
The links (of all nodes!) are working very well inside of org-roam.
Any idea how could go on with diagnosis here?
First I thought ox-publish has a problem with org-roam-v2 id-links. But 
the two new created nodes just for testing where working well. The older 
nodes (just 2 months old) also using id-links and where created with the 
same Emacs and org-roam version.

4.
ox-publish ignores newlines. Two short lines in the org-file becomes one 
line in the HTML content.

5.
I am not totally new to Emacs but quit fresh. So I have two questions 
about how to handle the documentation and help informations here.
a) I tried to "descrbie" the mode "ox-publish". But Emacs only offers me 
an "describe-mode" which describe all currently existing nodes. There is 
nothing like "describe-mode MODENAME". How can I handle that?
b) I another thread I was pointed to 
https://orgmode.org/manual/Publishing-options.html . There is no 
description about the options they are only listed. This does not help 
me. Maybe there are some useful options that could solve some of my 
problems. But without description I am not able to decide or know.

6.
Is there a way to integrated backlinks into output?
