> 🎉 MDIO v1 is out. Ingestion and export for SEG-Y is fully functional with templates! However, there may still
> be minor issues. Please report any issues you encounter.

> 🚧👷🏻 We are actively working on updating the documentation and adding missing features to v1 release. Please
> check back later for more updates!

**_"MDIO"_** is a library to work with large multidimensional energy datasets.
The primary motivation behind **MDIO** is to represent multidimensional
time series data in a format that makes it easier to use in resource assessment,
machine learning, and data processing workflows.

See the [documentation][read the docs] for more information.

This is not an official TGS product.

# Features

**Shared Features**

- Abstractions for common energy data types (see below).
- Cloud native chunked storage based on [Zarr][zarr] and [fsspec][fsspec].
- Standardized models for lossy and lossless data compression using [Blosc][blosc] and [ZFP][zfp].
- Distributed reads and writes using [Dask][dask].
- Powerful command-line-interface (CLI) based on [Click][click]

**Domain Specific Features**

- Oil & Gas Data
  - Import and export 2D - 5D seismic data types stored in SEG-Y.
  - Optimized chunking logic for various seismic types using MDIO templates.
  - Native [Xarray][xarray] data model and interface wrapper.
  - Import seismic interpretation, horizon, data. **FUTURE**

# Installing MDIO

Simplest way to install _MDIO_ via [pip] from [PyPI]:

```shell
$ pip install multidimio
```

or install _MDIO_ via [conda] from [conda-forge]:

```shell
$ conda install -c conda-forge multidimio
```

> Extras must be installed separately on `Conda` environments.

For details, please see the [installation instructions]
in the documentation.

# Using MDIO

Please see the [Command-line Usage] for details.
