==Partager le contenu==
and Wikitravel use incompatible licensing schemes. Wikipedia uses the GNU Free Documentation License ("GFDL"), while Wikitravel uses the Creative Commons Attribution-ShareAlike 1.0 ("by-sa") license ( see [[Project: Why Wikitravel isn' t GFDL| Why Wikitravel isn' t GFDL]] for more details). Because the GFDL and by-sa aren't compatible, it's ''' not possible to copy content''', in most case, between articles on Wikipedia and articles on Wikitravel.
There are some ways to do it, though. If you are the ''sole creator'' of content on Wikipedia, you can move it to Wikitravel; simply note on the [[Project:using talk pages|talk page]] that you're relicensing it under Wikitravel's Creative Commons license. Moving content worked on by other people requires getting their permission first; since both projects share the copyleft spirit, this shouldn't be difficult. The process is the same for moving material from Wikitravel to Wikipedia.
'''However''', think carefully before doing this, and discuss it with others. Wikipedia and Wikitravel have distinct goals, and forking large amounts of content from one project to the other creates wasteful duplication. In most cases, linking from one to the other would be a better choice.
==Faire des liens==
Linking to Wikipedia allows people to access encyclopedic information that doesn't fit into the framework of a travel guide. For example, the entry on the [[United Kingdom]] should have a thumbnail sketch of the country's history, but detailed information on Henry VIII is inappropriate. A link to Wikipedia's UK article would allow readers to find non-travel related information about their destination of choice, without stretching Wikitravel beyond recognition into an "everything you need to know about everything" guide.
If there's a page on Wikipedia that covers the exact same subject as a page on Wikitravel, but from an encyclopedic rather than travel guide point of view, consider making a twin link to the page. See [[Project: links to Wikipedia| links to Wikipedia]] for how to do this. You can also just add regular links to Wikipedia in the text of a Wikitravel article, using [[Project: Wiki markup| Wiki markup]].
'''However''', don't use links as an excuse to be lazy. Wikitravel entries should be useful and self-contained; links should provide ''additional'' information. Writing "Everything you need to know about France is [http://www.wikipedia.org/wiki/France here], except that there's a good bagel place in Lyon" is not helpful.
There are always various projects in the works at Wikipedia, similiar to Wikitravel's concept of [[Project: Expeditions| Expeditions]]. Some of these could be used by both Wikipedia and Wikitravel . See, for example, the work being done on [http://meta.wikipedia.org/wiki/Maps maps].
