Rex,
Courtesy of my MARC train ride this morning - here is my analysis on their schema - attached ZIP.
I've provided a couple of HTML reports in the ZIP that help understand their data model. Plus I provided comments on specific elements - see text below - and their data model - which overall - IMHO is somewhat "Fisher Price" XML. I provide an Excel spreadsheet of their dictionary.
Also - I used the renamer tool to fix their short uppercase names into new camel case names that are fully NIEM term reference compliant - and build a dictionary of those new terms.
My suggestion would be to re-use their dictionary components - but construct a new OASIS style EDXL aligned message structure, message metadata, and with a better information model.
Of course I have to admit a vested interest in this - you can potentially use the new CAM v1.8 blueprint system to perform this surgery - create a blueprint outline of the information structure - then insert the components in the appropriate places from the dictionary.
Then I rewrote their existing schema using XSD export - and this actually wrote their XSD back out better than their original (IMHO!) - a scary "first" for CAM - I've not seen it write schema better than humans before!
Overall I see that XML maturity wise the OASIS team here just is way better than CEN!?!? But we would say that wouldn't we?
Thanks, DW
====================
Things that raise eyebrows
Abbreviation of names - several arbitrary - not really saving byte count - e.g. Risk_Assessmnt - and DATIME - DateTime
Handling of address - unformatted 256 byte string - heavily overloaded - sometimes its milestone marker, sometimes address.
Name conflict / EVAC and EVACUATED
RGEO, EGEO - would be better to have parent Event, Resource - then child elements
ENV - bad abbreviation - better ENVIR
LOCTYPE - 0-80 - This is really Location Type and they have the code values in data dictionary. Probably a function of address.
URGENCY - seems slightly odd - better as URGENT boolean, or have values 0 through 5.
SECLASS - really Security Classification - some may have issues with their code system
ACTOR - this concept appears weird - suspect much better data model possible
OBS_DATIME - really not clear what OBS is!
TRIAGE codes - again think approach as in EDXL-HAVE is much better data model
POSITION - seems like the data model here is clumsy
Can produce a better organized heirarchical model - e.g.
They have
TSO_V20
- Context
- Event
- Resource
- Mission
alternative
OASIS_TSO
- MessageMetadata
- Event
-- Location
- Resources
-- Organization
-- Services
-- Weather
- Mission
-- Resolutions
This will also fix a lot of the naming issues and make a more consistent data model and allow
reuse of common patterns from EDXL, NIEM, LEXS

Hi Everyone,
I tried to send the main presentation on the Tactical Situation Object
(TSO) yesterday, but it was too large for the OASIS Server's limit, so I
am sending out the url for the presentation which I hope you will all
take the time to look at because i think we must take this effort into
account, and use it as best we can.

Since it specifies aspects of interoperability with CAP and used
EDXL-DE, I believe it may also be adaptable to some of the gaps in our
current set of EDXL specifications.
I will be incorporating it into the NCOIC All Hazards Alert and Warning
(AHAW) Capabilities Pattern, and it will also be the subject of one of
two specific AHAW Technical Patterns.
Cheers,
Rex
