# Red Arrow Dataset - Apache Arrow Dataset Ruby
Red Arrow Dataset is the Ruby bindings of Apache Arrow Dataset. Red Arrow Dataset is based on GObject Introspection.
[Apache Arrow Dataset](https://arrow.apache.org/) is one of Apache Arrow components to read and write semantic datasets stored in different locations and formats.
[GObject Introspection](https://wiki.gnome.org/action/show/Projects/GObjectIntrospection) is a middleware for language bindings of C library. GObject Introspection can generate language bindings automatically at runtime.
Red Arrow Dataset uses [Apache Arrow Dataset GLib](https://github.com/apache/arrow/tree/master/c_glib) and [gobject-introspection gem](https://rubygems.org/gems/gobject-introspection) to generate Ruby bindings of Apache Arrow Dataset.
Apache Arrow Dataset GLib is a C wrapper for [Apache Arrow Dataset C++](https://github.com/apache/arrow/tree/master/cpp). GObject Introspection can't use Apache Arrow Dataset C++ directly. Apache Arrow Dataset GLib is a bridge between Apache Arrow Dataset C++ and GObject Introspection.
gobject-introspection gem is a Ruby bindings of GObject Introspection. Red Arrow Dataset uses GObject Introspection via gobject-introspection gem.
## Install
Install Apache Arrow Dataset GLib before install Red Arrow Dataset. Install Apache Arrow GLib before install Red Arrow. See [Apache Arrow install document](https://arrow.apache.org/install/) for details.
Install Red Arrow Dataset after you install Apache Arrow Dataset GLib:
```console
$ gem install red-arrow-dataset
```
## Usage
