Quoting the relevant section from that document

  ... So far, based upon both user feedback and our own experiences, we feel
  that ZCPR is a significant contribution to the Public Domain, and
  everyone who has used it greatly prefers it over standard CP/M.

  ZCPR is being released for Public Distribution through the SIG/M
  User's Group of the Amateur Computer Group of NJ.  In the spirit of
  Public Domain software, ZCPR is by no means a panacea, but is IS a
  very nice stepping stone, and you are encouraged to feel free to
  modify it to please yourselves...

I am not the person who decides this sort of thing for Debian, but that
looks good to me.

Re: Public domain and DSFGness

2019-06-12 Thread David Given
Specifically? I'm trying to produce a CP/M clone distribution which is
DSFG-enough to ship with emulators (and also to run on real hardware should
people wish). The original Digital Research source has a nasty clause in it
which, AFAICT accidentally, means it can't be redistributed, so I'm finding
open source alternatives and bundling them together. What this is involving
is trawling through the archives trying to find free or public domain
pieces and piecing them together.

Example: the command shell I'm using (the CCP in CP/M terminology) is an
enhanced command shell alternative called ZCPR. The first version of this,
ZCPR1, which contains no copyright notice, and which was released in 1982
to the SIG/M public domain distribution group. I found the release
announcement (
https://github.com/davidgiven/cpmish/blob/master/third_party/zcpr1/Announcement.pdf)
which contains a passing reference to it being released into the public
domain. Is this good enough?

I was lucky there in that I found the announcement; there's plenty of
source which has nothing at all, not even a copyright notice. For example,
everything I've seen printed in Dr. Dobbs' Journal...

Thank you for promoting the preservation and spread of free software.

This is difficult to discuss in the abstract, because it so often
depends on peculiarities of the specific works and the documentation
surrounding them.

We try to keep these discussions to specific works that are actually
proposed to enter Debian.

Is there a specific work we can examine that you are working to package
for Debian?

Public domain and DSFGness

2019-06-12 Thread David Given
I'm doing some historical data preservation work, trying to track down
licensing for some really old (late 1970s and early 1980s) CP/M software.
I'm using 'good enough to get into Debian main' as my ideal win condition
here because it's a pretty high bar and if it's good enough for Debian it's
good enough for pretty much everybody. Plus, I'm hoping to be able to
produce a Debian package containing this stuff eventually for use in
emulators. Back then people were really slack about licensing. Typically
you'll see software contributed to a 'public domain' library with no
explicit license but which contains a bare copyright statement. I have to
write this off as if there's a copyright statement, the default license of
all-rights-reserved applies. However, frequently there'll be software which
doesn't contain a copyright statement at all.

I know that US copyright is weird; they didn't join the Berne Convention
until 1988. This means that works published without a copyright notice
automatically entered the public domain, all the way up to March 1st 1989
(provided they weren't subsequently registered for copyright).

This sounds like good news, but it may not be good enough for Debian ---
countries *other* than the US joined the Berne Convention on different
dates, so it's possible that a work could be PD in the US but still
copyrighted elsewhere. And even then I'd still need some kind of paper
trail to demonstrate that the work actually *is* PD.

So: from Debian's perspective, what's the degree of proof I need to provide
in order to demonstrate DSFG-ness of works such as this?

(I've found https://wiki.debian.org/DFSGLicenses#Public_Domain, but it's...
vague.)
