This is a straight dump of an Elasticsearch index and has some fields outside of "_source" that you can ignore.
Per the note below, we would like to switch back to a lighter-weight structure with fewer unnecessary fields some time in 2016, after we can perform a software upgrade that will make this possible.
Former file formats
If you wrote software to process our files before December 16th, 2015, it was designed to work with one of the following structures, and will need to be updated.

We intent to change back to this format some time in 2016, pending a related software upgrade.
Please let us know if you have any comments or questions about the new format, using our contact form.
