Hi,
jai-imageio-core is a Java package from Sun that includes plugins for Java that adds various image codecs, most notably TIFF. It would be really useful to have this in Fedora, so I'm thinking of packaging.
Unfortunately, there are a few issues:
GOOD: the website claims it is BSD https://jai-imageio-core.dev.java.net/
BAD: it contains jj2000 which doesn't seem like BSD https://jai-imageio-core.dev.java.net/source/browse/jai-imageio-core/src/sha...
GOOD: TIFF seems to be BSD https://jai-imageio-core.dev.java.net/source/browse/jai-imageio-core/src/sha...
I assume jj2000 can't go in to Fedora. I filed a Sun bugreport about this BSD confusion, but they are quiet on it. Am I wrong? Can jj2000 go in? (It would be useful.) Would I just need to strip jj2000 out of this package to make it ok for Fedora?
Thanks,
Adam

For two reasons, jj2000 can't go into Fedora:
1. The license it is under is non-free (only "JJ2000 Partners" have right to use, there is no right to modify, heavy use restrictions based on standard compliance). 2. JPEG 2000 is heavily patent mined.
You'd need to strip jj2000 out of the source tarball and ship a "clean" tarball to make it okay for Fedora.
Sun is historically really bad at licensing issues like this, although recently, they seem to be at least more interested in resolving these issues. Unfortunately, the patent issues around JPEG 2000 mean that even if this code was under an acceptable license, we still couldn't ship it.

Yeah, this is what I thought. Thanks for verifying this.

This seems strange to me: if patents are a problem then why does Fedora ship 2 other JPEG 2000 libraries already? (jasper since FC3, openjpeg since F7.)
Thanks,

Maybe they need to removed. Not every reviewer feels able to do a patent review, you know, and occasionally things get in that shouldn't.

The lawyers are thinking extra-double hard about this (thanks for pointing it out). When they decide something, I'll let you know.
In the interim, if you wanted to try to resolve the licensing issue with Sun, that might not be a bad idea. :)

Glad to be of help. :)

Here is my old bug report (they basically said they weren't shipping the code, which is not true, and left it at that):
https://jai-imageio-core.dev.java.net/issues/show_bug.cgi?id=162
I also tried contacting some of the jj2000 authors a year ago, and they basically said that as reference software for ISO, "the code becomes pretty flexible to use", but didn't know about open source interoperability.
