IP clearance

The former code base of OpenOffice.org used several external libraries and code with incompatible licenses (see also Third-Party Licensing Policy) that cannot be longer used in the Apache Open Office project or at least not in the same way. A first overview of critical stuff can be found on the "Migration" page in the community wiki. This page is intended to document the ongoing work of the IP clearance in more detail but still high-level.

The process will be redefined and improved over time and in the end we will end up with an automated process using the Apache Release Audit Tool (RAT) to ensure that we have always a clean code base for Apache Open Office.

The licenses are color coded according to their category on Third-Party Licensing Policy:

,

Error rendering macro 'highlight' : null

and

Error rendering macro 'highlight' : null

Contributors are encouraged to file issues for the intrinsic code changes. Issue 118566 exists as a parent issue for the 3rd party component removal tasks. Please add such issues as blocking issues to issue 118566.

The impact of removed or replaced libraries to the released OpenOffice is detailed here.

Status

1

Clarify legal usage of Category B (eg MPL) libraries

relevant for many critical libs

If allowed, upstream patches where possible and use binaries

Binary builds of libraries can be shipped with binary release of AOO.
Source code of libraries can remain on an Apache server but (like ext_sources of old OOo.)
BUT

  • source code of libraries is not shipped in a source release of AOO
  • instead it can be downloaded and built during bootstrap, but only when developer uses a configure option that is off by default

Clarify usage of GNU cp, GNU patch, GNU tar

Used during the build process

Native CP

Searching the mailing list archive reveals that GNU cp is a prerequisite for the FreeBSD's port.

No problem regarding IP clearance - see ooo-dev post. It is only used during the build.

Some work was done to mitigate the issue on BSD. In the long-run we should avoid its usage.

Clarify usage of boost

Used all over the place especially for smart pointers, extensive use in module canvas

 

clarify if license can be used under Apache
boost is widely used in the source code

Corresponding JIRA issue, found here, has been solved - Boost Software License Version 1.0 is now been classified as category A

Clarify usage of Oracle Berkeley DB

Used in modules l10ntools, xmlhelp and desktop

l10ntools: removal of 'dead code' using Berkeley DB
xmlhelp: code using Berkeley DB is also more or less 'dead' and can be removed
desktop: replacement already available

Not usable in Apache due to license - corresponding JIRA issue, found here

fix copyright/license statements in i18npool for the data files based on ICU.
There are missing/unclear copyright/license headers.

Used by line breaking
spell checking
word counting
word selection
etc.

 

Main part of these files are covered by Oracle's SGA - see oracle-sga-2-txt

Missing are the data files in folder i18npool/source/breakiterator/data/ which have IBM copyright header. These need to get proper license text.
As these are files are taken from ICU and are adapted to OOo needs, it is worse looking for new ones from ICU.

proper license information is now available in this folder
