An item's "Quality" determines its calculated stats. The Level at which the item spawns is combined with its "qualityLevel" along with some additional calculations to determine the value of those stats. In Destiny 2, most items don't have default item levels and quality, making this property less useful: these apparently are almost always determined by the complex mechanisms of the Reward system rather than statically. They are still provided here in case they are still useful for people. This also contains some information about Infusion.

Name Type Description
itemLevels integer:int32[] The "base" defined level of an item. This is a list because, in theory, each Expansion could define its own base level for an item. In practice, not only was that never done in Destiny 1, but now this isn't even populated at all. When it's not populated, the level at which it spawns has to be inferred by Reward information, of which BNet receives an imperfect view and will only be reliable on instanced data as a result.
qualityLevel integer:int32 qualityLevel is used in combination with the item's level to calculate stats like Attack and Defense. It plays a role in that calculation, but not nearly as large as itemLevel does.
infusionCategoryName string The string identifier for this item's "infusability", if any. Items that match the same infusionCategoryName are allowed to infuse with each other.
infusionCategoryHash integer:uint32 The hash identifier for the infusion. It does not map to a Definition entity.
progressionLevelRequirementHash Destiny.Definitions.Progression.DestinyProgressionLevelRequirementDefinition:integer:uint32 An item can refer to pre-set level requirements. They are defined in DestinyProgressionLevelRequirementDefinition, and you can use this hash to find the appropriate definition.
