Re: HTTP/OCP: OPES-Via to replace OPES-Processor and OPES-Service

Hi Alex,

Other OPES agents MUST use the OPES-Via header if they add their
tracing entries. All OPES agents MUST append their entries.

I stumbled over the second sentence. To me it sounds that all agents MUST
add their entries but what you want to say is that if an agents add its
entry,
it MUST append at the end of existing lists and not replace or insert
somewhere else


If an OPES-Via header is used in the original application message, an
OPES System MUST append its entry to the OPES-Via header. Otherwise,
an OPES System MAY append its entry to the OPES-Via header.

Again not so clear to me. "Otherwise" is if there is no OPES-Via header in
the
original app message, so how can someone append its entry to something that
does not exist. So how about:
Otherwise, an OPES System MAY add an OPES-Via header with its entry.

Typo in next sentence:
If an
OPES System is using both headers, it MUST add identical trace
entries except it MAY omit some or all trace-entry parameters from
the the OPES-Via header.
Double "the".

Regards
Martin

I will be making the OPES-Via modifications described below in both
drafts:

    - delete OPES-Processor and OPES-Service headers

    - add OPES-Via header that contains trace entries for
      OPES system, OPES processor, and callout services.

    - leave OPES-System header that contains OPES system
      identifiers only. These identifiers will be repeated
      in OPES-Via. This repetition will establish
      boundaries between entries for two OPES systems
      (consumer and producer) in a detailed OPES-Via trace.

Sounds good to me.
