The one I would like to use is the one from 2004. AFAIK that is the latest.

Perish the thought. I do not intend to copy guides. And even if I did I

I don't understand why a guide has a license. Can you explain please?

I don't want to do that. I really want to use the DDN code to DDN name
mappiing, giving proper copyright and trademark acknowledgement to the OCLC
for my mention of DDN and use of DDN subject names.

I am not going to be reverse engineering anything.

There must be some piece of the puzzle I am missing here. I am finding it
really hard to get to the bottom of what the issue is. There must be an
issue, judging from the very brief comment in the documentation, saying that
subject classification systems are generally not included in DSpace due to
"license issues".
All I want DSpace to do is to make it so that when I enter an article with a
DDN number of "physical chemistry" let's say, then one can navigate to that
article via the route science->chemistry->physical chemistry. Any of these
subjects not already existing are created on the fly and the subjects are
arranged as a hierachy. At the moment if I enter these subjects as dublin
core subjects they are all considered to be peers. And although I can enter
a DDN number in the dublin core, this does not cause any subject names to be
generated, even though a DDN number refers precisely to a subject.
