re-packaging iText

Tuesday, 30 September 2008

Hi, I wanted to bring into attention the recent development in the licensing of the iText.
This software was included in Fedora in the past but then removed due to licensing
trouble:
(i) https://bugzilla.redhat.com/show_bug.cgi?id=176981
and especially
(ii) https://bugzilla.redhat.com/show_bug.cgi?id=236309

According to the second link it was removed from F-7 because of the fact that it contained
some Sun-licensed files.

I downloaded the software from its current website:
http://www.lowagie.com/iText/download.html

The website claims a dual MPLv1.1 / LGPL license. Inside the package there is a text file
(core/com/lowagie/text/misc_licenses.txt), which I will paste to the bottom of this
email.

The most relevant parts of this txt file are in section (3). The original license ended
with the sentence: "You acknowledge that Software is not designed, licensed or
intended for use in the design, construction, operation or maintenance of any nuclear
facility." The word "licensed" caused the trouble in the past (see
comment#2 in (ii)) as it made the software non-free. But according to the txt file there
has been some email traffic between the original developer and iText developer on January
23, 2008 and the word "licensed" has been removed from that sentence in the
final license. 

I think we can re-consider packaging this software. I want to make sure we are on solid
grounds.

Please post your opinions.

Orcan

The original code was released under the BSD license, and contained the following extra
restriction: "You acknowledge that Software is not designed, licensed or intended for
use in the design, construction, operation or maintenance of any nuclear facility."

In a mail sent to Bruno Lowagie on January 23, 2008, Brian Burkhalter (@sun.com) writes:
"This code is under a BSD license and supersedes the older codec packages on which
your code is based. It also includes numerous fixes among them being the ability to handle
a lot of 'broken' TIFFs."

Note that numerous fixes were applied to the code used in iText by Paulo Soares, but apart
from the fixes there were no essential changes between the code that was originally
adapted and the code that is now available under the following license:

You acknowledge that this software is not designed or intended for

The main difference can be found in the final paragraph: the restriction
that the source code is not "licensed" in this particular situation has
been removed.

FYI: Brian also added: "A bit of history might be in order.
The codec classes that you used originally were based on some
classes included with JAI but not strictly part of JAI.
As of Java SE 1.4 an official Image I/O framework was
added in javax.imageio.... This frameork supports these formats:

Java 1.4: GIF (read only), JPEG, PNG
Java 1.5: Added support for BMP and WBMP
Java 1.6: Added support for writing GIF

The JAI Image I/O Tools packages (jai-imageio-core) were created
to support formats handled by JAI but not included in Java SE
as well as some new things like JPEG2000."
