IRI: https://w3id.org/gfo-light/Role

An object part can play a (e.g., functional) role in the whole object (e.g., the processor is part of the computer and has the task/function/role to process commands). A member (object) of a social group (object aggregate) can play a social role in that group (e.g., John is member of the football team and plays the role of midfielder). Objects can play processual or situational roles in processes (e.g., team A plays the home team role and team B plays the visiting team role in a football match) or situations (e.g., scorer and assistant role in a goal situation or roles played by a doctor and a patient in a risk/adverse situation in hospital) in which they participate. Objects can play relational roles in a relation/relator (e.g., wife role and husband role of the marriage relator).
A role is a relational entity that links a continuant (role player) with some context (object, object aggregate, processual entity, situational entity, relator), in which the continuant plays that role.

Situationc back to ToC or Class ToC

IRI: https://w3id.org/gfo-light/Situation

A situation can exist at a certain point in time or during a certain period of time and can be part or result of a process or another situation.

  • https://w3id.org/gfo-light/Continuant
    • Added: rdfs:comment "While the object parts are firmly connected to the entire object, the aggregate members are loose objects. When modelling a person, for example, you could consider their skeleton as an object and as part of the human body. However, if we look at bone finds in the context of anthropology, the skeleton can be modelled as an aggregate of individual bones. Another example is a computer. A kit of computer components is an object aggregate before assembly and an object (a computer) afterwards. However, if the components are thrown into the case without being correctly connected, it is not a computer, but the components are simply located in the case."@en
    • Added: rdfs:comment "Social or material (three-dimensional) objects, their groups/aggregates, parts and boundaries (two-, one- and zero-dimensional entities, i.e., surfaces, lines and points) are subsumed under the category Continuant."@en

A member (object) of a social group (object aggregate) can play a social role in that group (e.g., John is member of the football team and plays the role of midfielder). Objects can play processual or situational roles in processes (e.g., team A plays the home team role and team B plays the visiting team role in a football match) or situations (e.g., scorer and assistant role in a goal situation or roles played by a doctor and a patient in a risk/adverse situation in hospital) in which they participate. Objects can play relational roles in a relation/relator (e.g., wife role and husband role of the marriage relator)."@en
