The TEMPORA paradigm for the development of large data intensive, transaction oriented information systems explicitly recognises the role of organisational policy within an information system, and visibly maintains this policy throughout the software development process, from requirements specifications through to an executable implementation.
This paper introduces the External Rule Language (ERL) of the TEMPORA conceptual modelling formalism, and describes how it is used to captured and model business organisational policy. The syntax and semantics of the language are presented, together with a number of examples drawn from a realistic case study.
