[Pytables-users] How to store complex metadata?

[Eric J. <jo...@co...>]

Hello! I'm new to pytables and HDF5, and I'm trying to figure out how to
store my data. The issue of nested / complex attributes has come up:
ideally I'd like to store several large arrays in my file (with sizes
between 256 kB and 1 GB) and attach complex metadata to them, consisting
of tuples, nested objects, etc. But I want the metadata to be readable
from non-python tools, and evidently the attributes interface doesn't
currently support the non-scalar primitives. 

I'm curious what sorts of organizational schemes people have adopted for
their files to get around this limitation. Single-row tables? Just
saving data as strings? Or do people not run into problems with the
pickle'd metadata? 

Thanks for the help,
