Subject: Re: [cti-cybox] File Object


Yep... It just does not makes sense for them to be treated as 'less important' properties.  Lets just flatten them and make the properties optional. 


Thanks,

Bret

Is a file-system-properties-type ever used anywhere other than as the value of file_system_properties?  File-object is the only place it is used in the Host-based Objects document.  Is there a reason that it was ever made into a nested type in the first place?
 
I agree that the parent_directory_ref, file_name, file_name_enc, etc. properties should be flattened back into file-object.

Right now in the File Object some of the properties are artificially nested.  These properties deal with the file system aspects of a file.  The argument is that not all files have these and thus it should be nested. 

This IMHO, violates one of our core objectives of flatter is better than nested.  I feel it would be better to have these fields be flattened and just made optional.

This is something we do throughout STIX and is part of our holistic design principles.
