## About the Project

`og` is the command-line interface for the [Ontogen](https://github.com/ontogen/ontogen) version control system for RDF datasets in SPARQL triple stores. It provides an easy-to-use interface for version control capabilities similar to Git, but tailored for RDF datasets.

```sh
$ og init --adapter Oxigraph
Initialized empty Ontogen repository in /Users/JohnDoe/example

$ og setup
Set up Ontogen repository

$ og add data.ttl

$ og commit --message "Initial commit"
[(root-commit) 6fc09c94768204983d0409d28e0796ec3f17cef46e57c5cb1248424d3922040d] Initial commit
 3 insertions, 0 deletions, 0 overwrites

$ og log --changes
ec8108e3f4 - Initial commit (now) <John Doe john.doe@example.com>
   <http://www.example.org/employee38>
 +     <http://www.example.org/familyName> "Smith" ;
