FileIO integration

[SimonDanisch]

I see that the file format is registered in FileIO in https://github.com/JuliaIO/FileIO.jl/blob/master/src/registry.jl#L106
But it seems like there is no load function defined for it in HDF5 itself (JuliaGL/GLVisualize.jl#44).
Is there a reason for that?

Best,
Simon

No reason other than it hasn't been added.

I think the JLD one is also importing load and save, and with the redesign it shouldn't be.

Good to know! Well then, I might create a PR if If I find the time.

What should these do? load seems straightforward, just return an HDF5File. save is less, say it is passed an array, what should it call the dataset that it writes to? What happens if you call save again, write to a new dataset? Is save(fname,data) supposed to be able to be followed by load(fname)==data being true?

Are there any updates on this?

I was trying out DrWatson.jl and saving any .hdf5 file fails with

Error encountered while saving "/Users/jonas/Research/FooProject/data/sim/prefix_N=50.hdf5".
Fatal error:
ERROR: LoadError: UndefVarError: save not defined

Doesn't this work? (I haven't tried it) Looking at https://github.com/JuliaIO/FileIO.jl/blob/master/src/registry.jl#L303 it seems like it's in the registry?
