Introduction

Adapted from ADASS 2024 workshop.

Getting started

Created via a regular dictionary:

af_payload = Dict{Any, Any}( # To-do: see if type signature needs to be this general
    "meta" => Dict("my" => Dict("nested" => "metadata")),
    "data" => [1, 2, 3, 4],
)

Write and load with ASDF.write_file and ASDF.load_file, respectively:

using ASDF

ASDF.write_file("../data/my_asdf.asdf", af_payload)

af = ASDF.load_file("../data/my_asdf.asdf")

This contains a meta field, which is a dictionary that merges information about this library with af_payload:

af.metadata

af.metadata["asdf/library"]

Tagged objects

Supporting custom objects, extensions.

Array storage

ASDF.NDArrayWrapper(...; inline, compression)
