== The great Goals ==
Our mission is to '''make web content available offline''', with a primary focus on [http://www.wikipedia.org Wikipedia] and [http://www.wikimedia.org/ other Wikimedia projects].
Our target is to make Wiki content offline available, especially contents from Wikimedia projects such as Wikipedia.


The general goals we want to achieve:
We focus on extracting and encoding data from [http://www.mediawiki.org Mediawiki] for offline use. We would like to also add support for other [https://en.wikipedia.org/wiki/Wiki_engine wiki engines] and [https://en.wikipedia.org/wiki/Content_management_system content management systems] so that this can become a ubiquitous file format for offline usages.
* the file format is '''the most efficient''' and works on '''all platforms''', embedded devices and desktop computers
* the file format is '''used by all kind of publishers''' and even outside the Wikimedia community
* both reader applications and content files are '''freely interchangeable'''
* everyone can implement software for this file format because it is an '''open and documented standard'''
* there is at least one '''free implementation''' which is open source
* the free implementation '''can be used easily in other software''' to make it easy to use the file format without having to implement it


== Our way to achieve these Goals ==
We even believe the file format could be flexible enough to support any kind of web data.
=== The [[ZIM File Format]] ===
* compresses 900.000 articles (full german Wikipedia beginning 2009) to only 1.3 GB
* features a fulltext search index
* features native category and image handling similar to MediaWiki
* is fully documented on this website - [[ZIM File Format]]
* if you need help implementing it just contact our [[Mailinglists|mailinglist]]
* we are working on a [[ZIM File Archive]] to provide a central place to publish ZIM files including mirroring etc.


=== The openZIM implementation ===
== What openZIM is ==
* is all free and open source (GPL)
* The ZIM file format is the most efficient and works on all platforms, embedded devices and desktop computers.
* is based on [[ZIMlib]], a library written in C++
* The ZIM file format is used by all kind of publishers, even outside the Wikimedia community.
* provides a [[ZIMwriter]] to create ZIM files from a HTML dump (eg. a prepared database)
* Both ZIM reader applications and ZIM files are freely interchangeable.
* provides a [[ZIMreader]] as an example how to read ZIM files; ZIMreader acts as a local webserver
* Everyone can implement software for ZIM files because it is in a open and documented standard.
* there are some more tools such as the [[ZIMdumper]] to have a look into ZIM files or check them
* There is at least one free implementation which is open source ([https://www.gnu.org/licenses/old-licenses/gpl-2.0.html GPLv2]), the [[zimlib]].

Our mission is to make web content available offline, with a primary focus on Wikipedia and other Wikimedia projects.

We focus on extracting and encoding data from Mediawiki for offline use. We would like to also add support for other wiki engines and content management systems so that this can become a ubiquitous file format for offline usages.

We even believe the file format could be flexible enough to support any kind of web data.

What openZIM is

  • The ZIM file format is the most efficient and works on all platforms, embedded devices and desktop computers.
  • The ZIM file format is used by all kind of publishers, even outside the Wikimedia community.
  • Both ZIM reader applications and ZIM files are freely interchangeable.
  • Everyone can implement software for ZIM files because it is in a open and documented standard.
  • There is at least one free implementation which is open source (GPLv2), the zimlib.
  • The zimlib can be used easily in other software to make it easy to use the file format without having to implement it.

What openZIM is not

  • A publisher or distributor of content saved into the ZIM format. While we will make every effort to help those wanting to this we simply do not have the resources to do it ourselves. We do keep an index of known ZIM adopters at our archive page.
  • This project was started by the enthusiasm of volunteers and is mainly driven by them and not business interests.
  • Due to the small size of the core development team we are not be able to offer up a specific implementation of the ZIM format in your chosen programming language. We hope that by publishing the specifications and working together more implementations can be written by the adopters of the format.
