In this article we pursue two goals. The first is a further articulation of the dimensionality of the Dutch trait domain. The second is a detailed mapping of the factorial trait structure, one which includes intelligible and proper niches for various nuances of the trait language and for different interpretations of the main factors of personality language. In realizing these goals, we discuss the reliance on theory in structuring and modelling the domain in question, the type of model to be used, and the comprehensiveness versus the economy of domain representation. The advantages and disadvantages of the simple structure model and the circumplex model are commented upon, and a new framework that integrates these two models is presented. The present results provide confirmation of the existence of five major dimensions that cover the trait domain: (I) Extraversion or Surgency, (II) Agreeableness, (III) Conscientiousness, (IV) Emotional Stability, and (V) Intellect or Openness to Experience. The newly developed representational model, revealing are refined structure of personality characteristics, not only clarifies some of the problems faced in interpreting the Big Five factors, but also forms a starting point for applications.
