Interaction Dictionary

Because interactions are defined or described as patterns, their realization will require the involvement of entities or continuants: pattern ''parameters'' are bound to entities in the so-called real site work system (see the figure at Regulative Cycle), and bind:

• roles to macro or meso-level actors (stakeholders) in a country, a city, or to pico, micro or meso-level actors (stakeholders) in a sector;
• resources to resources (entities) accessible to the actors (stakeholders), for instance information available in the languages mastered by them (language options in the entity dictionary). Note that existing resource gaps for many stakeholders may make problematic the achievement of the intended interaction ''outcome'', or it may distort the cost-benefit equation.

Moreover, interactions can be bound together in variable ways, to create variants and achieve fit of the interaction to the situation, as indicated in the occurrent binding options. The Multisystemic therapy's First Principle (Finding the Fit) and the supporting distinction between the treatment model and the evidence-based treatment clarifies the utility of the variant creation.

Generalization is used with the meaning explained in Generalizations (Geometric) (Wikipedia).
