The scoprd file extraction service always outputs a file called scoprd-metadata.csv as the last depth 1 object in the response JSON.

The first line of scoprd-metadata.csv is used to uniquely identify this type of data file and its version:
#!$scoprd-metadata#!$v001
The number following the 'v' identifies the specific version of scoprd metadata CSV output that follows.

The second line of a version 1 scoprd metadata CSV is:
Filtered,Depth,Type,TypeStr,Subtype,SubtypeStr,MIMEType,MIMESubtype,Name,Infected,Suspicious,Uncompressed,Compressed,Ratio,Attributes,OS,Year,Month,Day,Hour,Minute,Second,CRC-32,MD5,SHA-1,Details,URLs,EmailAddresses,IPv4s,PhoneNumbers,CreditCardNumbers,BitcoinAddresses

Each subsequent CSV line contains the metadata associated with the defined columns.
