I ended up building out a hierarchy as well. But figuring out the structure of that hierarchy was not trivial at all. How does the name of a repeatable class (Algebra 1) fit with the name of a specific class (Algebra 1 Fall 2020 Section 2)? How does that relate to an area of math like algebra, geometry, number theory? How does that relate to things like context (ie problems about Minecraft, Lego, Physics, etc.) I developed a closed system of tags, and then gave people the ability to define aliases.
