NOTE Refer to the “FTAM Data Structures” chapter for detailed information on

setting the NBS-9 document type using the Ft_dt_nbs_9 structure.

NBS-9 Document Semantics

The following semantics are mandatory semantics for NBS–9 document

types.

• NBS-9 uses the Unstructured constraint set.

• Each data element contains the attributes of one ﬁle.

• The attribute_names parameter is only used on the open call. It

denotes the set of attributes to be returned for each ﬁle in the

directory. If this parameter is not present on the open call, the default

is to return all attributes.

• According to the NIST Phase III agreements, responders only need to

return the ﬁlename attribute. However, HP–UX responders return all

attributes as speciﬁed in the attribute_names parameter supplied on

the open call.
