URL Uniform Resource Locator
The address to a resource on the web — what you type in the browser's address bar.
Anatomy: https://wiki.thern.io/?q=rag#token = scheme (https) + host (www.thern.io) + path (/lexikon/) + query (?q=rag) + fragment (#token).
Good URLs are readable, stable and descriptive. Bad: ?id=482&cat=7. Good: /lexikon/rag/.
