The openZIM project has two different targets:
- the ZIM file format, an open, standardized file format to store Wiki content efficiently for offline usage
- an open source implementation of the ZIM file format consisting of the zimlib, zimwriter and zimreader
The openZIM project is sponsored by Wikimedia CH and supported by the Wikimedia Foundation.
Currently we support MediaWiki and are working on having creation of ZIM files for all Wikimedia projects. See our mission statement and our roadmap for more information.
