---------------------------------------

But it looks like that jar might be might be LGPLed, no?

------------------------------------

It looks like it is LGPL indeed (http://sourceforge.net/projects/java-unrar
).

I'm not familiar with every practical implication of every licensing scheme,
but if I'm correct LGPL means that the library can be used for both open
source and commercial uses. Without the obligation to open source your own
application. Am I right ?

------------------------------------

The java-unrar-0.2.zip package comes with a fairly permissive license.txt file. Though it might be a good idea to contact the author for clarification of the licensing terms.

You want me to talk to the guys ? Or is this for the 'legal' Tika department
? :-)

---------------------------------------

Ideally you'd talk to them and ask them to consider releasing the library under ASL v2.  Or maybe there already is something like that out there?

Jan Goyvaerts commented on TIKA-241:
------------------------------------

Isn't LGPL already allowing the usage of java-unrar in Tika ? So why should
they change their license ?

No, I believe we cannot have copies of LGPL software in Apache.

The reply from Edmund - developer of the java-unrar library.

Hello,
unfortunately the unrar license applies to most of the junrar code. it
does not allow to rebuild the rar compression algorithm the
decompression is open source and can be/was used (see licence.txt). the
parts that are independent from unrar are lgpl, but its difficult to
separate.

Best,
Edmund

Jukka Zitting commented on TIKA-241:
------------------------------------

My quick reading of the unrar license suggests that it would be acceptable as an Apache depencency. Instead of the partial LGPL licensing, would the java-unrar author willing to license the entire library under the unrar license?

-------------------------------

    Attachment: java-unrar-src.zip

Jan asked for and got a relicensed version of the java-unrar library. I'm attaching it here for the record.

I filed LEGAL-52 to get official clearance on the license terms.
