We put metadata of zim files into the namespace 'M'. These keys are defined:
In order to provide a description to each ZIM file that can be easily extracted we defined a special '''namespace M''' and a standardized set of keywords that should be used.


* Title - title of zim file
Every key is defined like an article, the key name is used as the article name, the key value is put into the article text. This way also metadata is compressed, but extendable. Further keys could be used in a ZIM file without breaking the standard but please be aware that maybe the openZIM project will define additional keys in the future. Any ZIM library reading this metadata should ignore missing keys / values and just return NULL values in such cases.
* Creator - creator of the zim file
 
* Date - create date (ISO - YYYY-MM-DD)
== Keys ==
* Description - description of content
{|{{Prettytable}}
* Language - ISO639-3 language identifier

* Relation - link to some external relation
