  Based upon trusted and confidential computing platforms, telecommunications
systems must provide guaranteed security for the processes and data running
atop them. This in turn requires us to provide trustworthy systems. The term
trustworthy is poorly defined with corresponding misunderstanding and
misapplication. We present a definition of this term, as well as others,
demonstrate its application against certain telecommunications use cases and
address how the learnings from ontologising these structures contribute to
standardisation and the necessity for FAIR ontologies across telecommunications
standards and hosting organisations.
