Subject: RE: [obix-xml] History Push
Perfect. I like just ignoring the
out-of-order records. Does that mean stopping at the first one or just
ignoring them and continuing with “good” ones? And I see Brian’s
text already required sorted records. From: Sublett, John
[mailto:jsublett@tridium.com] That’s definitely an issue. In
From: Richards, Dave
[mailto:drichards@trane.com] I like keeping it simple. Do we want
also to make some guarantee about order of records? Maybe specify that
the records are in chronological order and it’s legal to append all
records up to the one that violates the order? Or just skip out-of-order
records? I’m trying to avoid having to buffer and analyze the
entire request prior to processing. Does anyone else think that’s a
potential issue? From: Brian Frank
[mailto:brian.tridium@gmail.com] OK, to keep it drop dead simple we use the term "append" and
say you MUST push only newer data to the History (you can't push anything with
a timestamp before History.end) On Thu, Nov 12, 2009 at 9:42 AM, Sublett, John <jsublett@tridium.com> wrote: That’s a slippery slope. If we’re going to allow

We decided on our
call yesterday to call the History operation used to push new HistoryRecords
"append". But I'm not liking that term because it implies you
can only append histories to the "end" of the history and that you
can't insert older records. So I'm thinking
the correct term is "insert" and that no restrictions are made with
regard to the timestamps of the new records and the existing records. The information contained in this message is privileged and intended
