Load metadata from coscine if not in cache
Currently, the actual metadata of a file object seems not to be loaded anywhere, except one forces it in this method. However, if the metadata is not already in the cache and I ask for it on the file object, I would expect it to be loaded from coscine.
Therefore, I deleted the return None
such that a loading is attempted.
A question on the cache:
Currently, I do not see a method to easily populate the cache with the metadata in one directory. As such, the nice .dataframe()
method only provides a more or less empty DataFrame
- calling the dataframe
should ideally result in a 'get all metadata into cache and load DataFrame
with this data' request, IMHO.
