Keep on using DokuWiki everywhere (but not as an ELN)
while I understand the problem and agree that dokuwiki will not be an
ELN, I still cannot just forget the idea. I did some searching and it
seems an imortant step towards my needs would be trusted timestamping.
There is one implementation (or way of doing it) called linked timestamping.

The general idea is that you hash your new dokuments hash plus timestamp
together with the previous hash. Now and again you publish the hash in a
newspaper or similar. There seems to be some added security if you
aggregate your own hashes with those of other users hashes. There are
some disadvantages but the main advantage is that there is no PKI/key
management needed. The idea is quite old, like several 100 years with
paper and simple hashes, but also in terms of computer it stems from
stone-age (early 90ies), has been researched on, there are ISO, ANSI and
RFC documents.
