RE: [emergency] HAVE draft comment posted

["Tim Grapes" <tgrapes@evotecinc.com>]

Hey Rex,

I do understand where you are coming from, but my feeling is that now is the
time to adopt the NDR, before we have a release.  The NDR is conformant to
ISO 11179, and I don't think it would be considered a substantive change -
the structure and definitions are the same.  We would only be changing the
semantics.  It should not break existing applications since HAVE is only a
draft, and should only be used to this point for pilots and demos.  

I do believe the time is now to incorporate this, but perhaps I don't fully
understand the argument you put forth. As it stands, the TC has incorporated
naming logic not based upon an NDR.  We're simply recommending adoption of a
specific convention that will cure a lot of headaches down the pike.

Thanks,

Tim

Rex,

If we waited until the next version to adopt the NDR wouldn't that put us in
the position of having an immediate major release (v2.0) since I doubt that
it would be backwards compatible from the initial release?

Thanks,
Lee

Hi Tim,

I posed my initial response earlier, but I wanted 
to specifically address where in the process this 
should be taken up wrt HAVE.

My own feeling (subjective) is that it should be 
held back until a subsequent version, e.g. v1.1. 
or 2.0 because I suspect it will meet the 
criterion that a substantive change requiring a 
new 60-day public review has a threshold or 
trigger whereby a substantive change is one that 
"breaks" existing applications.

Objectively, we literally can't afford to hold 
this up, or vendors will produce their own 
menagerie of proprietary solutions. This is what 
happened for the OASIS SOA Reference Model TC 
(and current Reference Architecture SC). It has 
endured and continues to face the proliferation 
of ESBs and "SOA Fabrics"  jockeying for the 
inside track in the marketplace while we 
carefully crafted the Reference Model and 
continue to work on the Reference Architecture. 
However, because both the model and architecture 
are largely abstract, much like we can make the 
NDR we can, I believe, absorb ESBs and Fabrics, 
albeit with a very flexible shoe horn.

So while the comparison is not precise, the 
effect that ESB vendors have been running away 
with the marketplace still applies.

So we will have to attempt to incorporate NDR, 
crafting it as a non-breaking, non normative 
"best practice" in an appendix during and 
immediately after the 60-day review IF we have 
the time--which is to say, IF we are not swamped 
with industry comments. We will also need to 
include the advice that we expect to incorporate 
a general-purpose NDR methodology in the next 
version of HAVE and EDXL_DE along with all 
subsequent members of the EDXL family.

We may be able to do this because what we are 
doing is establishing a methodology for NDR, not 
a controlled vocabulary in itself. If NIEM is 
looking for a the greater restriction of its own 
controlled vocabulary, which is what we feared 
early on in Mike Daconta's initial statements, we 
would have a greater challenge, and I would have 
to take the position that we are required to 
ensure international applicability over any 
specific national systems.

Either way, its a tough pill that it is better to 
take now than postpone because it is not going to 
taste any better, and likely to ferment into much 
worse, if we wait.

Cheers,
Rex
