+- [[https://git.km3net.de/km3py/km3io][km3io]]: a tiny Python package with minimal dependencies to read KM3NeT ROOT files
+- *Goal*: provide a **standalone**, **independent** access to KM3NeT data
- Uses the [[https://github.com/scikit-hep/uproot][uproot]] library to access ROOT data
- Provides convenient wrapper classes
- Maximum performance due to numpy and numba
-- Data are read lazily
+- Data are read lazily:
- only loaded into memory when directly accessed
- apply several cut masks on huge datasets without reading them into the memory
** Installation
- Dependencies:
- Python 3.5+
- - uproot (installed automatically)
+ - uproot (a small Python package, installed automatically via ~pip~)
+- *No ROOT, Jpp or aanet* required to read ROOT files
- Releases are published on the official Python package repository:
- ~pip install km3io~
+** Why is it so cool?
+- Runs on Linux, macOS, Windows, as long as Python 3.5+ is installed
+- Every data is a ~numpy~ array or ~awkward~ array (~numpy~ compatible array of complex data structures)

+* Accessing Online (DAQ) Data
