Beyond its own intellectual neatness, ask yourself the purpose of what you are creating. person:scarlett johansson may be gender:female, if you think that useful, but species:human, species:mammal, and species:animal may be going a little far). Reasonable people disagree on what is 'clearly' a parent or sibling, or what is an excessive level of detail (e.g. This can obviously get as complicated and over-engineered as you like, but be careful of being too confident. adjusting bikini and adjusting swimsuit are both grandchildren to swimwear. adjusting bikini is a child to both bikini and adjusting clothes, and bikini is a child to the new swimwear, which is also a parent to swimsuit.

Note this is not a loop-like with siblings, loops are not allowed-this is a family tree with three 'generations'.

Consider how adjusting bikini might fit on this chart-perhaps this: graph TB a picture of just Ridley).Įven a small slice of these relationships can get complicated: graph TBī - B1Īlso, unlike siblings, which as we previously saw are n->1, some tags have more than one implication ( n->n): graph TBĪ - BĪdjusting swimsuit implies both a swimsuit and adjusting clothes.

Samus comes inextricably from Metroid, but not everything Metroid is Samus (e.g. Anything with character:samus aran (and thus anything with character:zero suit samus) would have series:metroid. In this instance, anything with character:zero suit samus would also have character:samus aran. If you search series:league of legends, you would expect to see all instances of character:ahri (even if, on rare occasion, she were just appearing in cameo or in a crossover).įor hydrus terms, character x is in series y is a common relationship, as is costume x is of character y: graph TBĬ - B - A If you search vehicle, you would expect the result to include all cars. Similarly, a rifle is a firearm, face tattoo implies tattoo, and species:pikachu implies species:pokémon which also implies series:pokémon.Īnother way of thinking about this is considering what you would expect to see when you search these terms. Any time you see a car, you also see a vehicle. Certain tags always imply other tags, and it is annoying and time-consuming to type them all out individually every time.Īs a basic example, a car is a vehicle. Tags often fall into certain heirarchies. The relationship will also apply retroactively. Tag parents let you automatically add a particular tag every time another tag is added.
