[edit] hardware

• the term HDO_00001054 (hardware) is currently subclass of bfo:function.
• this class hierarchy seems ill aligned - it should be somewhere under material entity and has function "hardware function"
• current definition. Physical components which a data processing system comprises.

hardware:
    definition: A material entity which realises a hardware function.
hardware function:
    definition: A function which inheres in a material entity and which is realised when that entity is used as part of or as a whole data processing system by virtue of its physical make-up.
