Open-source Python package for handling Multi-Regional Input-Output (MRIO) tables with high flexibility.

## Overview

The `mrio_toolbox` is a Python library designed for manipulating Multi-Regional Input-Output tables. It provides tools for loading, processing, analyzing, and exporting MRIO data from various sources including EXIOBASE, WIOD, EORA, and custom datasets.

This package supports:
- Extraction and conversion routines for widely used MRIOs (EXIOBASE, WIOD, EORA, Gloria, GTAP, Emerging, Figaro)
- Fast and lightweight data storage
- Numpy-style indexing and selection
- Standardized manipulation routines for reproducible research: aggregation, cleaning pipelines, mathematical operations, mapping algorithms

In comparison to higher-level MRIO-handling packages such as [pyMRIO](https://pymrio.readthedocs.io/en/latest/index.html) and [MARIO](https://mario-suite.readthedocs.io/en/latest/intro.html), `mrio_toolbox` focuses on providing low-level routines for advanced MRIO users.

## Installation

Install the latest stable version using pip:

```bash
pip install mrio_toolbox
```

Or install from source:

```bash
git clone https://codeberg.org/tbeaufils/mrio_toolbox.git
cd mrio_toolbox
pip install -e .
```

## Documentation

The `mrio_toolbox` package builds on two major concepts: MRIO, and Parts. 

MRIO are high-level objects that can inherit an arbitrary number of Part instances.

Part instances contain the actual data. Each Part represent a different quadrant of the MRIO table. As a convention, we use t for the inter-industry matrix, a for the matrix of technical coefficients, y for the final demand and va for the value added. A Part can have any shape and more than two dimensions.
Parts support numpy-like indexing, on index and labels. They can be created in insolation or as part of an MRIO object. A new Part can be created by manipulating another Part.

Check the [example](https://tbeaufils.codeberg.page/mrio_toolbox/Example%20use.html) section of the documentation for hands-on examples.
