META Files

Each of the data feeds is described by an associated plain text file with the same name as the .xml file with a .meta extension. These files are updated approximately every two hours to reflect changes within their respective feed file. The .meta file contains information about the specific feed file including the last modified date and time, the size of the file uncompressed, and a SHA256 value of the uncompressed file:

lastModifiedDate:2015-09-10T08:40:09-04:00
size:1273382
zipSize:91619
gzSize:91477
sha256:ac782e2db403e2b09ad5dd676501e8755fda3f2bef347b7503491700c6c5eaff

The META file should be used to determine if a given feed has been updated since your last import. This helps prevent unnecessary downloads of the .zip or .gz files and should result in a reasonable use of less than 200 requests per day.
