What is the relationship between a resource and a category?
We can consider a resource to be one of many members of a very broad category, as the unique instance of a category with only one member, or anywhere in between.
What factors affect the size of a category?
The size of the category—the number of resources that are treated as equivalent—is determined by the properties or characteristics we consider when we examine the resource.
What are active resources?
Active resources create effects or value on their own, sometimes when they initiate interactions with passive resources. Active resources can be people, other living resources, computational agents, active information sources, web-based services, self-driving cars, robots, appliances, machines or otherwise ordinary objects like light bulbs, umbrellas, and shoes that have been made “smarter.”
