PrOnto has been built via standard minimization principles from the ontology engineering literature (Brank et al., 2005;Bandeira et al., 2016).
PrOnto does not truly fit for legal reasoning: PrOnto only defines the main concepts involved in the GDPR and their inter-relations, but it lacks another component necessary for legal reasoning: defeasibility (cf. (Casini et al., 2015))
