Subject: RE: [emergency] EDXL/CAP Survey

Sorry to jump into the discussion but I had to respond to some of the points made about the GJXDM. My name is Winfield Wagner and I just jointed your TC as an Observer.  I don't know if there is rule that Observers should be seen not heard but I must argue some points this time.  

I agree that GJXDM could be a big honking middleware if it is implemented incorrectly.  Thinking in terms of replicating every column of every database in most of the current legacy systems in one-off schemas that have a lot of extension to meet every unique element of the participating sharing agencies is not a good idea.  

If you think in terms of sharing 95% of the information through standardized schemas that have no extensions, we could accomplish the goal of sharing a big chunk of information between agencies, domains and levels of government and public sector. 

As far as performance, I can not argue the fact that using GJXDM slows down everything.  At the same time a delay in obtaining information seems to be a little sacrifice for getting to information that I never had or would take hours, days and week to get. 

I believe GJXDM was meant to be a transport mechanism that allowed silo-ed systems to share information not to replace existing database structures or query applications.  Yes it can be used for that but we just to need to think in terms of sharing at a crawl before we start sprinting.

I argue that it can be implemented; because my company has.  We have been able to demonstrate with our Regional Information Sharing and Intelligence 
Project that GJXDM can be implemented for real world problems.  We were able to distribute information from multiple regional and local sources to a single intelligence analysis tool. In my schemas, I use pure GJXDM with no extensions that can represent 95% of the information needs of over 8 difference agencies' representation of a Field Interview.

As far as cost, it is much cheaper then maintain custom code for every data exchange point and if done correctly can reduce costs associated with the hard document exchanges that exist today. 

Is GJXDM ready for prime time?  Not yet but it is not going to go away.  It may mutate into the NIEM but criminal justice community has accepted it. That acceptance is not based on federal dictum but on a bottom up acceptance that we need to share information.  I have been in the criminal justice information business for 25 years and it is the first time I have seen agencies making a business argument on the benefits of sharing.  That was self evident at the first GJXDM user conference held last week.  Over a two day period, we picked up 15 separate leads/opportunities and one contract proposal related to GJXDM installations. The next day we were notified of three separate RFP's requiring the use of GJXDM.

I am not advocating the use of GJXDM for the Emergency Management domain. My only experience is in the area of law enforcement so I can not tell you the benefits and problems with using GJXDM in that domain. But do not think GJXDM is going away.  It will have an impact on emergency services and how it communicates with other domains. 

So as an observer and deemed by the voting member of the TC, I will go back in my hole and watch from the sidelines.
Thank you for you time

Ok.  Here is the other view:

As I sit here looking through the DRM, I am lightly convinced 
that the chances the public safety industry will be implementing 
this soon are functionally zero.

The problem of any top down design is the bottom up legacy that ensures that

no clean break can ever be made given an active procurement cycle.
No one starts from scratch and the active legacy is much more 
important to the agency than Federal mandates.  Changing a tire 
on a moving car in an intersection is dangerous work.

GJXDM as a big honking piece of middleware for bits on the 
wire is possible.  It isn't likely that the relational system 
schemas will be changed to match the unwieldy and verbose 
GJ elements:

1.  Not a good design for relational systems.  Performance 
    requirements for queries typically range from one to 
    four seconds for a query of medium complexity.  These 
    designs favor too much standalone context.
2.  It is too disruptive to unhorse all of the 
    current systems to convert their data.
3.  RDF is a non-starter.  Show us the commercial 
    frameworks (say operating systems and programming 
    frameworks with more than 10% of the market) that 
    support it today because even if supported today, 
    there is about a three to five year gap to fielding of 
    robust, secure, reliable products.
4.  IEPs are a good idea but every agency we 
    deal with has its own reports, some State mandated, 
    some agency mandated, some JIT ad hoc.  How many 
    years are given for any local agency to convert to 
    the IEPs (keep in mind how many states are still UCR 
    despite NIBRS)?

At some point, DHS and DoJ are going to realize that 
there isn't enough funding to get this done and they 
will vastly simplify the requirements.  The Federal 
budget is strained and there is no end in sight to the 
Executive-initiated events that are draining resources.

A roll-out plan that confronts the reality of the 
procurement and legacy issues is needed.  It will 
have to be much simpler because submarining these 
languages in by reference to GJXDM means that the 
vendors and procurement officials will waive the 
bulk of GJXDM in favor of the 'most useful' subset 
as determined by the local agency.

Hi Len,

CAP is now included in GJXDM, so RFPs contingent on the GJXDM are 
also axiomatically contingent on CAP compliance within GJXDM, if 

DHS will likely stipulate CAP in its applicable RFPs. the Public 
Forum for the Data Reference Model yesterday included CAP because it 
was part of the pilot we (Starbourne) will be doing for the Semantic 
Interoperability Architecture effort for September. I will keep this 
group apprised of that work as it proceeds.

EDXL is likely to be a key piece of NIMS as it gets built out. We are 
hammering on the Distribution Element again today.
