Article Format

All content put in a zim archive must be put in the  namespace.

Entries can be :
 * Articles : Html content intended to be displayed to the user
 * Resources : Any other kind of file, mainly intended to be included in articles or other resources (css, images, js, ...)

Article Entries
Article's contents are full html pages. (including any  tag or any css, scripts and fonts links).

Article's content must be utf-8 encoded.

ZIM contents are addressed using the entry's path without the namespace. The references in articles HTML code (, , etc.) must be valid and usable by a classical web browser (ie, URL-encoded following the RFC 1738 rules).

Absolute URLs, ie. with a leading slash (/), are forbidden, because this avoid including the ZIM contents in any HTTP sub-hierachy. URLs must consequently be relative.

URLs with namespace are also forbidden as the namespace may be hidden by the libzim. URLs must not go "too up" in the directory hierarchy. is still possible if the entries is in a sub-directory.

Resources Entries
There is no strong constraints on resources entries :
 * Mimetype must be correctly set.
 * We advice textual contents to be utf-8 encoded but we cannot enforce it, it depends of the resource and how it is used.
