The Offline Reader Expedition is a Wikitravel Expedition to make it possible to download and use Wikitravel articles off-line (not connected to the Internet), especially on a personal digital assistant (PDA).
There is also a plucker (.pdb) continent-by-continent offline eBook download available at: tripsteps.com/ebook
Wikitravel has two main target media: online use over the World Wide Web, and offline use in hardcopy (paper) form. It's possible, however, to have electronic files that you can read on a computer or a PDA even when you aren't connected to the Internet (shocking!). This could be very useful for some travellers (although there are plenty of us who can't or don't want to use a portable computer or PDA). Being able to navigate through a number of articles with a hand-held device could make it a lot easier to get around.
Since there are no database dumps available yet you might try to use httrack to download all pages.
To define one or more target formats for off-line reading
To define the desired user interface for obtaining and using Wikitravel articles
There are a few main off-line readers for PDAs. Most define their own file format, although some can read plain text files and HTML files.
Palm Doc No particular reader. These are native plain-text files for Palm devices -- no images or hyperlinks.
AvantGohttp://www.avantgo.com/ Proprietary software. Does images and hyperlinks, widely supported by Web content providers.
TomeRaiderhttp://www.tomeraider.com/ Shareware program. There's already been some work to make Wikipedia available in TomeRaider format, but it's the entire database and adds up to close to one gigabyte of data. WikiTravel will be a much smaller database, though. There are 2 different versions of the Wikipedia database available - with images and without.
Pluckerhttp://www.plkr.org/ Free Software. This has some nice features, including better support of images. It also has software included for generating new Plucker pages, which might be useful for Wikitravel.
Encyclopodiahttp://encyclopodia.sourceforge.net/en/ Free software. Encyclopodia is a Linux-based package which runs on 1st through 4th generation Apple iPods. Its source-tree includes a tool to convert Mediawiki dumps offline for easy parsing on the iPod.
Raw XML As outputted by MediaWiki. Can be converted to a number of formats, imported to a local MediaWiki install, or used directly (as done by Wikifilter. http://wikifilter.sourceforge.net/)
Wiki2Touchhttp://code.google.com/p/wiki2touch/ Free application for Jailbroken iPod touches and iPhones. Takes an xml.bz2 dump of wiki databases and turns it into it own format not much larger than the original file. Works exceptionally well.
WikiTaxi is an offline reader, viewer, and browser for MediaWiki wikis. WikiTaxi works extremely well on huge Wikipedias (English, German, Japanese, etc) *.xml.bz database dumps. Multi-language support makes sure it works with WikiTravel also. For Windows. Freeware.
Of these, Plucker seems like the nicest one. It's being actively worked on, and it is Free Software,
and that means that you can use it without charge, that you can give it away to others, and that you can even modify the program (or pay others to do it for you) to customize it or add the features you want.
Raw XML dumps of the database would likely be the technically simplest option for Wikitravel to release its data. These dumps are large, highly-compressible, single files which are, among other things suitable for distribution via BitTorrent. Interested parties could convert these to their desired format for use or redistribution.
There are several levels of UI we can provide.
Download a single article. The user would be able to download a single article in Plucker format. The link for Plucker download would be next to the "Printable version" link.
Download a group of articles. Most travellers won't be going to just one place. It'd be nice if they could add articles to a "shopping cart" of some kind, and then download all the articles in their "cart" at once.
Update articles offline. Of course, the dream scenario is that Wikitravellers could download articles to their local computer or PDA, edit the articles on the road, and then upload the edited versions when they get back to an Internet connection. This is probably a little pie-in-the-sky, but it sure would make sure we had up-to-date info.
