Subject: Fwd: RE: EDXL-Reference Information Model

Hi Everyone, Renato,

I am forwarding to the TC list Karen's reply to the message I sent 
out last week to Karen and Renato and this list, and copying Renato. 
I haven't heard back yet from Renato, but I did want to let the TC 
know that I hope we can have a Requirements Document ready for the 

I want to take this opportunity to anticipate what I think may well 
be the central discussion around which specific topics will be 

I think we will have two primary lines of thought wrt the EDXL-RIM:

1: Defining Abstract Concepts (with Reference URLs where appropriate) 
for Common Components:
	EDXL-DE Dependency;
	ValueListTypes with Keywords (hopefully using XMDR and ISO 11179 NDR);
	geo-oasis: Where for TargetArea - Location citing 
OpenGeospatial Consoritum GML;
	ContactInformation  using CIQ;
	Scheduling Types reusing what we have developed for EDXL-RM;
	Conceptual Conformance to DRM 2.0 as feasible;
	Conceptual Conforimance to NIEM as feasible;
2: Abstract Information Modeling:
	Hierarchical DOM-like Modeling of Information Structure;
		EDXL-DE Message Routing;
		Security and Non-Repudiation;
		Individual Specification Content Payload;
	Message Exchange Patterns;

I would expect that the structure of the RIM will resemble the 
EDXL-RM Information Model Renato contributed to the Document

>>  Hi Renato, Karen,
>>  I'm writing to get the task of building the EDXL Reference
>>  Information Model started (EDXL-RIM). The TC voted last week to make
>>  this a priority and to spend a large proportion of the upcoming
>>  Face-to=Face meetings at the OASIS Symposium 2007 on establishing
>>  Scope and Requirements. I volunteered to work with you to build a
>>  EDXL Framework or Skeleton document from which we can work in the
>>  meeting to get this effort underway. We are scheduling these
>>  discussion for Afternoon in San Diego, California so that, hopefully,
>>  you can participate as much as possible. I will also be attending via
>>  teleconference, so I expect the pace will necessarily have to
>>  accommodate us. While it is not optimal, it is doable.

>>  of specifications from having been involved with it from the start
>>  that I can just jump in and start reeling off requirements, and I

>>  Although I am attaching my bare-bones start of a Requirements
>>  Specification, I am including a first pass at the first text section:
>>  **************************
>>  Document Scope and Purpose
>>  This document states the Functional Requirements for the overall
>>  family of Emergency Data Exchange Language specifications. As such,
>>  these requirements should be formulated as the abstract principles
>>  which govern the enumerated elements within the individual
>>  specifications.
>>  For Instance, the Emergency Data Exchange Language Distribution
>>  Element 1.0 Specification (EDXL-DE.Spec_v1.0) specifies <targetArea>
>>  for geospatial or political area with specific information regarding
>>  the originator's intent with regard to the routing of an EDXL message.
>>  It used a naming convention with an initial lower camel case letter
>>  that has since been replaced a convention that uses an initial upper
>>  camel case letter. This document should explicitly state the broad
>>  naming and design rules that have been adopted.
>>  Moreover, the EDXL-RIM SHOULD define the concept of <TargetArea> or
>>  <Area> as an abstraction that can be used for the EDXL-DE or the
>>  EDXL-Resource Messaging (EDXL-RM) specifications, or any future EDXL
>>  specifications. Such a definition SHOULD be sufficently broad and
>>  abstract to allow the basic concept to be used consistently across
>>  the spectrum of EDXL specifications. As such, this  requirements
>>  specification SHOULD NOT include as a requirement the most concrete
>>  level of information, such as the originator's intent or specifically
>>  that both geospatial and political MUST be included because that
>>  would not be true for the element <TargetArea> in EDXL-RM that does
>>  not include political information nor an area defined by intent.
>>  **************************
>>  I don't want to go any further than this right now. I would like to
>>  set up a time for a teleconference with you if I can so we can add
>>  just enough to the Requirements document to use as a Framework to
>>  channel discussion in the Face to Face meeting. We need to have the
>>  TC's input.
>>  Hopefully we can decide which SC should carry this work forward.
>>  While the Messages and Notification SC has handled the EDXL family so
>>  far, I am fairly sure we will see a specific sponsored recommendation
>>  coming from the Infrastructure TC which will fall within EDXL as
>>  well, so it is a decision that needs to be taken carefully. However,
>>  since we have championed this concept for a while, we should help get
>>  it launched in the best way we can.
