 **JZFS** is an open-source, cloud-native version control filesystem based on Git protocol for data management and publication with a command line interface and a Python API.   With JZFS, you can version control arbitrarily large data, share or consume data, record your data’s provenance, and work computationally reproducible.
 
 JZFS adapts principles of open-source software development and distribution to address the technical challenges of data management, data sharing, and digital provenance collection across the life cycle of digital objects.

 Compared with code in software development, data tend not to be as precisely
 identified because data versioning is rarely or only coarsely practiced. Scientific computation
