This exercise is designed to help learners become more familiar with the British National Formulary (BNF). It is designed to improve learners knowledge of the medication as well as confidence in finding reliable and accurate information quickly. By completing the quiz questions learners will become more confident in finding their way around the BNF.
This activity is designed to help learners develop a familiarity with the BNF, its various sections and the information it contains. The vast majority of the quiz questions can be completed with reference to a reasonably up-to-date copy. Some questions may require the use of additional resources such as a physiology textbook or an Internet search. The value of the activity is in looking for the information as much as about the right answer.
Meta-modelling plays an important role in model driven software development. In this paper, a graphic extension of BNF (GEBNF) is proposed to define the abstract syntax of graphic modelling languages. From a GEBNF syntax definition, a formal predicate logic language can be induced so that meta-modelling can be performed formally by specifying a predicate on the domain of syntactically valid models. In this paper, we investigate the theoretical foundation of this metamodelling approach. We formally define the semantics of GEBNF and its induced predicate logic languages, then apply Goguen and Burstall’s institution theory to prove that they form a sound and valid formal specification language for meta-modelling.

The rainforests of Borneo have many dangers, especially for the more vulnerable prey species. But, these threats may be reduced if different species work together to deter a predator.
