RE: [kmip] Error in kmip-spec-v2.0-csd01 for Locate operation

Thanks Tony,

That makes sense and matches the info I posted in my follow-up email. On my first read of the spec this was unclear (and on subsequent reads, Iâd argue that the spec is a bit ambiguous). I think that the spec would benefit from some clarity around this.

Iâd also be interested in hearing what people think about making the attributes structure optional. Missing or empty would have the same meaning.

Hi John,

The intent of the spec (based on my understanding when implementing the deltas) is that you are required to include the "Attributes" structure in a Locate operation. There is no corresponding requirement that says the Attributes structure must be populated. This is an intentional construct to signal that a locate request is being provided with no search parameters, and is differentiated from a poorly formed request which fails to include the Attributes structure.

In short:
Attributes contains the list of zero or more attributes.
The list container must be present. The list itself can be empty.

Cheers,

Tony Cox

Section 6.1.27 of kmip-spec-v2.0-csd01, third paragraph, states: "If no attribute is specified in the request, any object SHALL be deemed to match the Locate request."

Table 230 lists the Attributes item as REQUIRED in the Request Payload. This contradicts the text in the third paragraph which infers that the Attributes item is OPTIONAL.
