ZIM (file format)
The format allows for the compression of articles using, features a full-text search index and native category and image handling similar to MediaWiki, and the entire file is easily indexable and readable using a program like Kiwix - unlike native Wikipedia XML database dumps.
In addition to the open file format, the openZIM project provides support for an open source ZIM reader called Kiwix.
ZIM stands for "Zeno IMproved", as it replaces the earlier Zeno file format. Its file compression uses LZMA2, as implemented by the xz-utils library. The openZIM project is sponsored by Wikimedia CH, and supported by the Wikimedia Foundation.
