January: Project Start

The basis for the openZIM project was established during 2008 when Tommi Mäkitalo, maintainer of tntnet, created an open source version of the ZenoReader published by DirectMedia on their yearly Wikipedia DVD. This new tntzenoreader became part of the Wikipedia DVD 2008/2009 in October 2008. As the idea of having a common, free file format and tools that are open source to solve the Wikipedia offline problem spread to other projects a need of extending the works on the tntzenoreader arised.

In December 2008 the decision to found a project was made by formerly involved and new interested parties. Wikimedia CH was asked to provide funding to make the project possible: A server for development was needed as well as ressources for having regular developer meetings to keep the project alive. The swiss Wikimedia chapter agreed in sponsoring the project by giving 4000 CHF for 2009.

DirectMedia was asked if we are allowed to use their name "Zeno" for the new project, as the file format is based on Zeno. As they used Zeno as a trademark and were about to sell their portal "zeno.org" they requested the project to use another name, so we came up with ZIM as the abreviation for "Zeno IMproved".

Manuel Schneider rented a rootserver in Frankfurt and set up a server with Wiki, Subversion and virtual machines for development on Windows and Mac OS X. Project team members can get a SSH account on the server to write access to SVN and use the server for long-running tasks such as ZIM file creation.

February: 1st Developers Meeting, Official Launch of openZIM

The first Developers Meeting of openZIM with five participants took place in Schopfheim, Germany. The project team officially formed and the first documentation was put into the wiki.

Some changes to the new ZIM format have been discussed and a plan for 2009 has been decided, including making a Wikipedia DVD for LinuxTag 2009.

For a full report of our meeting see Developer_Meetings/2009-1.

April: Participation at the Wikimedia Conference, Starting Cooperation with Wikimedia Foundation

The Wikimedia Conference was taking place for the first time and put together the yearly Wikimedia Chapters Meeting and the first MediaWiki Developer Conference, both happening at the same time in Berlin.

Manuel has planned to attend the MediaWiki Conference for his own interest but it was already full, then he was invited to join the Wikimedia Chapters Meeting as a board member of Wikimedia CH had to cancel his participation.

While the Chapters Meeting is an internal meeting of all Wikimedia Chapters around the world and the topics discussed there are Wikimedia-internal and of political / strategic nature there were still some opportunities to discuss about the openZIM projects and its ideas.

In the we got contact to members of Wikimedia Israel, Wikimedia Italia and Wikimedia Polska working which were interested in the Wikipedia offline topic. After the Chapters Meeting Manuel still had some time to meet up with the MediaWiki developers and discuss with them.

A few weeks later we were contacted by the Wikimedia Foundation. Erik Möller (deputy CEO) wanted to learn more about the project. A phone conference took place with Erik Möller, Brion Vibber (WMF CTO), Tomasz Finc (WMF Developer) and Manuel Schneider (openZIM). During this conference the decision was made that the Wikimedia Foundation wants to support openZIM and look into integrating the ZIM format into the dumping process on http://download.wikimedia.org/. Furthermore a one-click functionality to create ZIM files from MediaWiki should be evaluated.

June: Participation at LinuxTag, 1st Wikipedia DVD

LinuxTag is Europe's biggest exhibition and conference for free and open source software. openZIM applied for a booth in cooperation with tntnet, so we got one booth for both projects.

By this opportunity we created nice graphs to show how the ZIM file format is used and how it works internally. These were printed as A2 posters and showed at LinuxTag.

Sponsored by Wikimedia CH with 1000 CHF we published a set of 500 DVDs holding the german Wikipedia and the zimreader application as binary and source code.

On a lightning talk Manuel presented the idea of openZIM and gave away many DVDs to the interested audience. On discussions with Linux4Africa and Skolelinux we found new adopters for the ZIM format and software for the usage in schools.

For details see LinuxTag_2009.

August: Participation at Wikimania

November: 2nd Developers Meeting, Major Changes to the ZIM Format

Developer_Meetings/2009-2 The 2 major things about the meeting was the support of the Ben NanoNote platform and major changes in the file format.

2 guys from the qi-hardware team joined our meeting and we helped them to port zimlib to the Ben NanoNote.

We decided also to change the file format to support indexing by url and title. Also compression was changed from bzip2 to lzma, since lzma is faster to decompress and library support is finally good enough. We also dropped the QUnicode format inherited from the zeno file format, since it only helps to sort german data better. So we decided to simplify ordering and use simple string compare.
