URL construction of a typical PUG-View request. A typical PUG-View request URL encodes three pieces of information (the kind of annotation to retrieve, the record specification, and the desired output format) into one-line URL. Optional parameters specific to some requests may be added to the URL after the question mark (“?”). The available values for the ⟨ANNOTATION⟩ part are “data”, “index”, “annotations”, “categories”, “neighbors”, “literature”, “structure”, “image”, “qr”, and “linkout”
