Hi, it seems that [DimensionalData](https://github.com/rafaqz/DimensionalData.jl) and [AxisKeys](https://github.com/mcabbott/AxisKeys.jl) have quite a bit overlap.
What are the considerations I should keep in mind for choosing between these two packages?

I posted the same question on Zulip a while ago, and @mcabbott gave a comprehensive answer including other packages as well:

Basically,
- AxisKeys.jl: the structure is more lightweight; more composable especially in terms of using specialized arrays for `axiskeys`
- DimensionalData.jl: more complex with more features built-in
Both are `AbstractArrays` 🙂
