Every term this system uses, defined once, with what it means here rather than in general. Search it or filter it.
Data forms are the ways a number becomes a picture. Elements are the 6 things a composition can be made of. Operations are the 10 things you can do to them. Constructions are named combinations of the two, 21 in all. Layout terms describe arrangement inside the frame, Type terms describe setting, and System terms are the ones specific to how this library is built.
An element plus an operation gives you a construction: circle + repeat + scale + offset + crop = Arcs. That is the whole grammar.
