I have open sourced a simple "C" based utility under GPLv3 which will
convert Wikimedia Foundation XML Wikipedia Dumps into a format
which allows easy compliance with the GFDL for off-Wikipedia wikis.
This utility allows the XML dumps to be parsed and [[en:<Article
] tags to be inserted into
the dump at the end of articles. Dumps converted with this
tool point back into the source Wikipedia artcles and edit history when
imported into MediaWiki.
The tools allows tags which use interwiki_sql links as well as simple
URL addresses. This code is provided to the Wikipedia Community
and other consumers of Wikipedia content with an easy way to insert GFDL
compliant tags into master XML dumps and import them.
The source code, binaries, and makefile are available at:
