Request: Metadata

[janEbert]

I think it would be great if JuliaDB could save some form of metadata (maybe a dictionary) as a kind of header in the same file as the database.
This would make managing and sharing different datasets much easier.

What sort of API are you thinking of for this metadata?

[janEbert]

Possibly something along the lines of

using JuliaDB
potential_path = "my_2d_flat_dataset.jdb"
metadata = load_metadata(potential_path)
if metadata[:dim] == :2d && metadata[:hierarchy] == :flat
    println("We found the desired data!")
    db = load(potential_path)
end

Sorry for not including an example earlier. What do you think?
