"A URI path parameter is part of a path segment that occurs after its name. Path parameters offer a unique opportunity to control the representations of resources. Since they can't be manipulated by standard Web forms, they have to be constructed out of band. Since they're part of the path, they're sequential, unlike query strings." -- [Dorian Taylor](https://doriantaylor.com/policy/http-url-path-parameter-syntax)
