Show definitions of standard types

Record standards define what information to collect and how to format it, for example when registering a new patient.

Data definitions and terminologies define the format of individual data items so they can be consistently represented, for example dates or medication names. Reference sets and controlled lists are also included.

Technical standards and specifications specify how to make information available technically including how the data is structured and transported.

Information codes of practice are legal or best practice guidelines on how information should be handled.
