Jubako is the new binary container format. It allows you to build (almost) any kind of container, simply.
From generic files archive to dedicated file format, build it on top of Jubako !

Feature

• Partial compression: Content can be compressed or not. Decide whether the content is compressed or not is made at content level.
• Direct access: You don't need to extract the whole archive on the file system or in
  memory to access a content.
• Customizable: The metadata (stored in the entries) are not defined. Each use case can (and must)
  specify which metadata to store. Each entry can point to one content (basic use case) but it is not necessary. An entry can point to several content or none.
• Incremental: Is possible to create archive containing only the difference between an existing archive and the content you want to store (TODO)
• Adaptable: The content can come in different variants. For example, images can be in low and high resolution.

What is Arx ?

Arx is a file archive format, base on Jubako.
It is the equivalent of tar or zip, but with all the features of Jubako.

Who am I ?

I'm Matthieu Gautier (@mgautierfr), the creator of Jubako.
I'm a freelance developer since 10 years and I'm creating software for twice of that.
And I'm living in Lyon, France. A great city ! If your passing by, ping me !

My first job was (among other things) to package assets in video games.
15 years later, I'm the maintainer of the kiwix project and the openzim format.
Now, I'm starting a new format (the 15th according to xkcd) which reuse the good ideas I seen around but customizable and adaptable.

Why sponsoring me ?

I've decided to spend a lot of time on improving Jubako and Arx.
This means that I have to reduce my missions as a freelance developer.

By sponsoring me, you allow me to spend more and more time on the project and help me to build a strong foundation for this new way of packaging and distributing content.
