	Description		A set of things working together as parts of a mechanism or an interconnecting network; a complex whole. In Return Project, in the ontological model, a system is categorized as 1) made by humans (artificial systems) and 2) a natural system, which is a set of elements that arise naturally, without human construction. Both types of systems are coupled, that is, human systems interact with natural systems and vice versa in multi-levels and aspects. There are several kinds of human-made systems (e.g., urban systems, economic systems, judicial systems) and natural systems. An urban system is a human-made system placed in a specific space and exists at a specific time. It is composed of essential parts, which are Resource and Population. A Resource is an essential part of one or more urban systems, for instance, a river can be a resource for different countries, and different cities. The resource is subcategorized as Urban Infrastructure and Agent as a Resource.
