Many specific research questions were identified during consultation related to the production of this document, and we have introduced these to the main text or included them in an accompanying appendix where possible. However, in constructing the framework, the emphasis has been placed on defining the broader structure of research: the principles, methodologies, practices and contexts of the subject. In adopting this approach, we hope to provide a basis for the design of individual projects and for the consideration of more specific research agendas without unnecessarily restricting the scope for creative research by prescribing a limited set of research questions based on the most prominent current concerns.
