title: Loading hdf5 files into python xarrays
body: <p>The python module xarray greatly supports loading/mapping netCDF files, even lazily with dask.</p>
  
  <p>The data source I have to work with are thousands of hdf5 files, with lots of groups, datasets, attributes - all created with h5py.</p>
  
  <p><strong>The Question is</strong>: How can I load (or even better with dask, lazily map) hdf5 data (datasets, metadata,...) into an xarray dataset structure?</p>
  
  <p>Has anybody experience with that or came across a similar issue?
  Thank you!</p>
