Attributes
An NBS-9 file returns directory information about other FTAM files; the selection of
attributes for which values are returned varies with the FTAM implementation and
possibly with the individual NBS-9 file. As part of a directory request, your application
passes a bit-string parameter that can identify up to 18 file attributes (the ones for
which you would like to get values). The number after each parameter in this list
indicates the parameter position in the bit-string. When a bit is “on,” or set, you are
requesting a value for the corresponding attribute.

Attributes
FTAM attributes fall into two classes: activity attributes and file attributes. Activity
attributes pertain only to activity during an ISO FTAM association. File attributes are
characteristics of a file in a file storage system.
Within each of these two classes, FTAM attributes are divided into four groups: kernel,
storage, security, and private-use. Kernel group attributes are always defined and
available for any file in an FTAM filestore. Storage group attributes relate to storage
characteristics of a file. Security group attributes provide file security information. ISO
8571 does not define the private group.
