Subject: RE: Changes in 1.1 spec draft - in scope? (UNCLASSIFIED)

Re 8.5


Depends how deep we want to go.


1.       Can I apply tags to point? Seems straight-forward. Do I do it through the oBIX interface or by some other means?


2.       Can I query all points with a given tag to build my collection? Seems straightforward. Can I secure points by tag type? Not sure there.


3.       If a tag is for a complex object, say a haystack an ahu with multiple ahurefs, can I query an ahu and ask for all refs? Can I query a point indicated by an  ahu-ref be traced back to the ahu? Do we support complex queries such as “return all AHUs for which at least one of the AHUREFs is not a colddeck? How about AHUs associated with *this* chillerPlant but associated with any boilerPlant other than *that* How far down this road do we go?


4.       How recursive are tag queries lets say we have an  dischargeAirTempSensor associated with a discharge associated by AHUREF to an AHU associated with a chillerPlant. Can I query, through oBIX, all dischargeAirTempSensors associated with a chillerPlant?


5.       Is a System that is otherwise 1.1 compliant but does not support tags conformant?



I guess if adding tags is out of scope (1), then not being able to perform (1) causes no issues.  If conformance is “able to query by tags if they exist”

My comments...


6.6.1:  I'm not sure if this enhancement is worth breaking the 1.0 core since it is a requirement (to flatten the types).  It seems like an issue better left to implementation or extensions.  If we were going to include this in the 1.1 spec I would prefer dealing with it in a way that does not break the core "is/of/in/out" attributes.  I would prefer adding an attribute(s) to accommodate ("inherits") flattening. How have others dealt with this issue?


8.5: This adds value, doesn't break 1.0, and I think it is fine for 1.1 scope.


13.1, 13.2, & 13.2.5:  I think we should keep this.  It adds a lot of value and solves some big headaches.  If this had been around in the beginning I would've been a quicker adopter on some of my projects.

Subject: [obix] Changes in 1.1 spec draft - in scope?





Per discussion in our most recent meeting, I am notifying everyone about the latest draft of the 1.1 oBIX spec, and requesting comments on whether any of the proposed changes constitute too much of a scope change for 1.1, versus moving these changes into the upcoming 2.0 versions.  The 2.0 version is intended not to be a core specification, but a collection of extensions to allow better enterprise interaction.  So, with that in mind, the changes that are currently in the WD10, and which are under consideration for removing from 1.1 and moving to 2.0, are:


*         Compact contract flattening (6.6.1)


*         Enabling tagging/metadata presentation (8.5)


*         Alternate History formats via URI (13.1, 13.2)


*         Compact history records (13.2.5)



Please take a look at the WD10 documents and comment to the list about whether you think these changes should be in-scope for the 1.1 version of the oBIX spec.
