Subject Re: [PATCH] Change Copyright notice to ASF
Date Sat, 11 Sep 2004 05:06:12 GMT
Hi Jalud and other Derbies,

Regarding the adding of the ASF license I propose the following, in
order to move forward. I've tried to take care to reflect all parties
involved, including myself ;), and this is what I came up with.
(comments, suggestions welcome)

------------------------------------------------------------
a) Replace the IBM license information (as propopsed by Jalud) of the
(.java) files with the following, but keep a modified the IBM
copyright line, per http://www.apache.org/licenses/LICENSE-2.0.txt:

   Copyright [yyyy] IBM Corp.

   Licensed under the Apache License, Version 2.0 (the "License");
   you may not use this file except in compliance with the License.

I've gotten signals within IBM that IBM still retains the copyright
and that the copyright notices should reflect that. Which there are
provisions for (http://www.apache.org/licenses/LICENSE-2.0.html#apply).

------------------------------------------------------------
b) Add ASF copyright notice to files modified under Derby license.
I.e., ADD the following when there is a community contribution to a file.

   Copyright 2004 The Apache Software Foundation.

In 2005 use either of:

   Copyright 2005 The Apache Software Foundation.
   Copyright 2004, 2005 The Apache Software Foundation.

Leave the IBM notices intact.

One could easily write (perl) scripts that adds/updates these
notices (using information from "svn log ...").
I've done so previously for perforce.

------------------------------------------------------------
c) The [yyyy] in the Copyright should be the years that is contained
in the original files as donated to ASF, using the format 
"YYYY" or "CCCC, YYYY" when applicable.

Let me explain where these years come from, since I did a scripted
update of all of them a few months ago. I traced back in our source
code repository from when the file was first created (CCCC).
YYYY was set to the year the file was last "move"/changed package
name, or accumulated at least 5% (of the lines) had been modified.

Apache says in: http://www.apache.org/dev/apply-license.html :

As I understand it, if there are no other copyright than the Apache
(would IBM's ever be removed), then Apache considered it important
that the first year mentioned reflects the creation of the file.
Otherwise, it seems that the years should reflect when it was first
publicized by ASF.

Apache says on http://www.apache.org/dev/apply-license.html:
> ... years given start with the first publication year of the file
> contents (the authored expression) ...

------------------------------------------------------------
And to comply with http://www.apache.org/dev/apply-license.html :

d) Copy http://www.apache.org/licenses/LICENSE-2.0.txt into /LICENSE

e) Create a file /NOTICE containing:
---
This product includes software developed by
The Apache Software Foundation (http://www.apache.org/).

This software consists of voluntary contributions
made by many individuals on behalf of the Apache
Software Foundation, and was originally based on
Cloudscape software, copyright International
Business Machines Inc., http://www.ibm.com .
---
( inspired from public record IBM donations
  http://www.apache.org/foundation/records/ )

------------------------------------------------------------
f) I further suggest that the updates not be submitted as patches, but
instead that a (perl?) script is given that is tested, and can be run
by a committer.

I'm aware that Apache says:
>For Apache software, we strongly recommend checking the diffs of each
>file and commit only one directory at a time (bottom-up) so that the
>changes can be verified without overwhelming reviewers.

But with 1298 .java-files, I think even a 123 directories with a patch
each is really pushing it.

I suggest the script that performs the updates on a directory and its
subdirectories, that it only touches files that are actually changed,
so that it can be re-run at any time, only affecting files that need
change. Having a script also allows any future changes to be readily
applied.

------------------------------------------------------------
g) I'm still trying to get a copy of the IBM Corporate CLA to read, since
it may be easier to comply with it then, and might simplify some
issues. Maybe somebody at Apache has an available copy?

I'm currently working for IBM: 2 years DB2 Everyplace; Now 2 years Cloudscape; 
Before that I did research on databases - Scalable Distributed Data Structures:
3 years in Amsterdam (CWI); 3 years at Linköping University, Sweden.
