Subject: RE: [emergency] EDXL/CAP Survey
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
required.
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.
Ciao,
Rex
