This chapter develops an ontological framework with which to identify the points of intersection between, and to undertake an epistemic integration of, existing disciplinary positions and concepts. The embedded, relational and emergent (ERE) model is argued to be both ontological, and a theory. It contains a number of key conceptual components that together form basis of a sport coaching ontology. This ontology is nested in a broader philosophical and bio-psycho-social ontology. Although sport coaching is mainly associated with athlete learning and performance improvement, the temporal dimensions, and the number of stakeholders involved, are likely to lead to multiple coaching goals in any context. The d'Arripe-Longueville study of French judo coaching is re-described and re-explained through the ERE model – this might not provide 'new insight' into coaching, but shows how the model works. Through the ERE model it also possible to points to gaps that could be addressed through a depth approach if the work were extended.
