What does it do?
================

This TYPO3 extension is an add-on to the `schema
<https://extensions.typo3.org/extension/schema>`_ extension. It provides
additional `schema.org <https://schema.org/>`_ terms related to
health and lifesciences: `https://schema.org/docs/health-lifesci.home.html
<https://schema.org/docs/health-lifesci.home.html>`_.

For more information about the schema extension have a look into the
:ref:`documentation <ext_schema:introduction>`.


.. _vocabulary:

The schema.org vocabulary
=========================

The schema.org vocabulary is evolving, approx. every 2-3 times a year a new
version is `released <https://schema.org/docs/releases.html>`_. The TYPO3 extensions are
updated when changes are made to the according vocabulary. The classes for the
type models and view helpers are generated by the `schema-generator
<https://github.com/brotkrueml/schema-generator>`_ library.
