AbstractMetaArrays

AbstractMetaArrays is a Julia package designed to provide a flexible and efficient framework for working with metadata-enriched arrays. It enables seamless integration of metadata with array operations, making it ideal for scientific computing and data analysis.

Features

• Support for metadata-aware array operations.
• High performance and compatibility with Julia's array ecosystem.
• Easy-to-use API for defining and manipulating metadata.

Installation

Install AbstractMetaArrays using Julia's package manager:

using Pkg
Pkg.add("AbstractMetaArrays")

Usage

using AbstractMetaArrays, StructArrays
using Unitful: km, ustrip,uconvert,m
using CoordRefSystems

struct Ray{T}
    point_x::T
    point_y::T
    direction_x::T
    direction_y::T
end

rays=StructArray(Array{Ray{Float64},1}(undef,1000))
a= majoraxis(ellipsoid(WGS84Latest)) |>
   x-> uconvert(km,x) |> ustrip

# Example usage
meta_rays = SimpleMetaArray(rays, 
    Dict("datum" => (WGS84Latest,:datum),"major_axis" => (a,:normalization)),
    Dict("units"=>(km,:unit),"normalized"=>(false,:Bool)))
