If the URL by itself is insufficient for retrieving the content (the client must supply additional query parameters, for example), use a service access point instead. An access point that allows a representation of the scheme to be accessed by interacting with a programmatic service; for example, through the ADL Thesaurus Protocol. If the service is intended for human interaction (for example, requires reading HTML documents), use a web-interface URL instead.
