Ah, I understand now. I hadn't realized the difference between `_metadata` and `common_metadata` and I didn't realize `_metadata` contained info for each file. I was thinking it was just another name for `common_metadata`. Yes, I think your diagnosis is spot on. As long as the files make it to the `Dataset` constructor in-order they should be returned in that order. However, because of the unordered_map that you pointed out, those files are not making it to the constructor in the right order.
