.. _cli-show-version-doi:

================================
``wwtdatatool show version-doi``
================================

The ``show version-doi`` command prints the `DOI`_ associated with
the current version of the ``wwt_data_formats`` software package.

.. _DOI: https://help.zenodo.org/

Usage
=====

.. code-block:: shell

   wwtdatatool show version-doi

Prints out the DOI of the current version of ``wwt_data_formats``.

Notes
=====

While the version DOI in and of itself does not provide any information that
isn’t already provided more clearly by the :ref:`cli-show-version` command, the
version DOI can be used to properly cite your use of the ``wwt_data_formats``
software in an academic context.

While each release of ``wwt_data_formats`` has its own version DOI, all releases
of ``wwt_data_formats`` share the same “concept DOI”, which can be obtained with
the :ref:`cli-show-concept-doi` command. Unless you specifically know that you
need the concept DOI for a particular application, you should use the version
DOI.
