That is a problematic part of IT-business, and insights, feelings and 
experiences for and in such situations can be best developed, if someone 
is directly involved.

Sorry Ralph, but: No, that's not right.
What we did is exactly what you have mentioned: We gave it ontologics, 
which includes semantics and ontology based semantics. Or let say it 
with other words: Our [....]FS is based on R4 and could be described 
very rough as H. Reisers vision of the further development of R4 in a 
Semantic[/Ontologic] Web style, which could be seen as the R5 you 
mentioned, but has now another name that fits better with semantics and 
ontologics.
And we have explained such a semantic feature in a discussion on this 
mailing list. But just right from the start we got the advice by the 
actual maintainer:
"Go away!"
Later, we were also heavily attacked by other members of this mailing 
list with statements like "stealing", "that's rude" and so on.
Since then we are not allowed to talk about our R4 based fork.

Please read also this whole thread again, especially the messages of the 
days 19.04.2009 and 20.04.2009.

We hade started around the 1995s while no one was really interesting in 
these kind of semantic, ontologic and ontology based technologies.
And we have not done some thinking, it was in fact much more.

Sorry again, but: No, that's not right. The EU-funded research project 
Nepomuk is largely based on stolen technologies from my company (eg. 
ontology for file system). After the presentation of our Linux based 
distribution with an R4 forked file system, that we are not allowed to 
mention here, and the ending of the monetary support of the related 
research project with tax money we gave only in small steps new 
informations about our technology so that it couldn't be stolen further 
by that project, members of the project, a newer project, a company, or 
others. That's the real reason and has nothing to do with the technology 
itself, but in fact more with international governmental and industrial 
issues. Or said with oher words: We have the thumb on it.
Please, understand all that this kind of technologies, including R4, are 
no kindergarden games.

We have to say sorry once again, but: No, that's wrong. Our R4 based 
file system is not only conceptually ready since 2006.

Sorry, but: Our R4 and NoSql based file system is not only conceptually 
ready since 2006. Also, we had developed it, because several FUSE based 
approaches exist for these kinds of applications, but are to slow or not 
consistent from the point of view of their architectures. R4 has several 
features that fit exactly and a FUSE based R4 makes really no sense, 
because it is already a file system. Believe us, we were already there 
more than 8 years ago.

If the explanations were to harsh, then we beg for apologize.

With all the best and Yeah
