+A ``softwareDependency`` is a complex object. The properties are the following:
 
 -  ``name`` - **mandatory** - The name of the dependency (e.g. MySQL,
    NFC Reader)
+-  ``source`` - where the software can be obtained (e.g. a URL)
+-  ``license`` - the type of license, may be broad (e.g. 'open', 'free', 'proprietary', 'commercial'
+   or more detailed (see e.g. https://spdx.org/licenses)
 -  ``versionMin`` - the first compatible version
 -  ``versionMax`` - the latest compatible version
 -  ``version`` - the only major version for which the software is
    compatible. It assumes compatibility with all patches and bugfixes
    later applied to this version.
 -  ``optional`` - whether the dependency is optional or mandatory

+A ``hardwareDependency`` is a complex object. The properties are the following:
+
+-  ``name`` - **mandatory** - The name of the dependency (e.g. Rasberry Pi)
+-  ``source`` - where the hardware can be obtained (e.g. name of the manufacturer)
+-  ``specifications`` - the (minimal) specification the hardware must meet to support the software
+-  ``optional`` - whether the dependency is optional or mandatory
