When we talk about language in KNiTO we refer to three items:
KNiTO interface: KNiTO currently only offers English. This does not mean that it does not really have other interfaces. Actually it has a number of other languages but while we are during our first launch year we have decided to focus on English speaking markets. We will soon add French, as are based in Canada.
Our main platform, PUBNiTO supports both English and Arabic (store.pubnito.com) but this is just for our B to B world.
Books: We can have books in any language. All our components support multi languages.
Metadata and Details: Details such as name of the author or description of a book which is displayed in the store, Tags, etc are currently able to be in any language but for consistency we only accept English data. This is because in future we will be adding true multi lingual feature so that when you change interface say from English to French, all metadata also changes from English to French.
