             Summary: Suggestion for History Object
                 Key: OBIX-227
                 URL: https://issues.oasis-open.org/browse/OBIX-227
             Project: OASIS Open Building Information Exchange (oBIX) TC
          Issue Type: Improvement
          Components: OBIX 1.1 Schema, OBIX 1.1 Specification
    Affects Versions: OBIX 1.1 PR03
         Environment: Brian Frank
            Reporter: Toby Considine


14.1 History Object - HistoryCollection
The terms "collection" and "HistoryCollection" seem sort of generic and confusing.  How about "collectMode" and "HistoryCollectMode" 

14.1 History Object - prototype
Glad to finally see something like this.  However I am not quite sure how it works.  I think we need an example.

14.2.4.2 History Query as Preformatted List
This design requires two separate round trip requests which is pretty terrible for performance.  I think a requirement of this design is that once the history point is learned by the client system, that it can request history data with a single HTTP request.  I don't see that having an oBIX XML response before getting the data provides much value.  I would suggest this: just add a "format" field to the HistoryFilter object and when specified the result is returned in the requested MIME type.
