A knowledge systematization approach is used to articulate knowledge chunks (atomic building blocks) that are in the public domain.
The Interactions Dictionary is one of the foundational dictionaries. It identifies several families of interactions, depending on the entities involved.
- Socio-cultural: a socio-cultural interaction is among persons and is usually based on kinship, friendship, or it is implied by an encounter that is non-commercial or non-institutional
- Techno-commercial: a techno-commercial interaction is among persons and organisations that are involved in the trade, production and consumption of commercial goods and services, where exchanges involve money, and employment contracts may bind principals.
- Institutional: An Institutional interaction is one in which at least one of the principals involved is a collective or government agency in its capacity defined by statutory or customary law.
- Semiotic: An semiotic interaction involves a person, or a sensing/actuating system (the interpretant), a sign (often content on an information carrier), and a referent (that is denoted by the sign). Modelling and learning are typical examples of semiotic interactions.
- Regulative: A regulative interaction is one in which one or more persons seek to affect (improve or detoriate) the condition of another actor, a livelihood or a worksystem, usually with a specific target (see also CRB Methodology). Health care and education could be classified as particular forms of regulative interactions.
