Subject: Re: [emergency] GJXDM vs EDXL Distribution isses
This email thread is disturbing... I would hope this TC can avoid the "not invented here syndrome" and focus on reusing schema elements where the concepts are equivalent or can be aligned. -------------------------- Sent from my BlackBerry Wireless Handheld -----Original Message----- From: Art Botterell <acb@incident.com> To: emergency@lists.oasis-open.org <emergency@lists.oasis-open.org> Sent: Wed Dec 29 15:43:52 2004 Subject: Re: [emergency] GJXDM vs EDXL Distribution isses At 9:34 AM -0500 12/29/04, Ham, Gary A wrote: >To be GJXDM compliant we would probably have to change the "eventType" >to something more akin to "EmergencyEventTypeCode"... I'm not sure whether "compliant" is the right criterion. Our functional goal is "compatible"... framing it in terms of compliance transforms a technical issue into a political one. I'm not sure that's either necessary or wise. Not necessary because we have the mechanism of namespaces to allow domain-specific element design choices to be made "close to the ground," nearer to functional concerns and farther from bureaucratic ones. It gives us a viable alternative to the grand-unified-data-model-of-everything approach, which I'm afraid may be self-defeating in its scope. And not wise for several reasons: 1) Adopting a stance of "compliance" to one user group... in this case, the justice community... necessarily distances us a bit from others... fire, transportation, health, etc. While I realize that Justice is ascendant in post-9/11 America, we're part of an international standards organization and those of us who've been at this for awhile have seen these trends shift back and forth over the decades. 2) There's a learning curve here. As Gary points out, just because the GJXDM was the earliest and largest doesn't mean it got everything right. We need to leave the door open for learning and improvement. (After all, the US had the first color television standard in the world... and as a result spent the next forty years looking at the worst color tv pictures in the world.) 3) As mentioned above, the wider the scope of a data model, the more technical and political inertia it accumulates. Keeping a degree of compartmentalization lends flexibility, so long as there's a mechanism (e.g., namespaces) for preventing collisions. Now I'm not arguing against adopting an ISO 11179-based naming scheme. I'm just suggesting that we ought to think carefully and explicitly before slipping into an assumption that we're somehow obliged to comply with some other group's scheme. - Art -- Art Botterell Common Alerting Protocol Program Manager Partnership for Public Warning www.PartnershipForPublicWarning.org (707) 750-1006 To unsubscribe from this mailing list (and be removed from the roster of the OASIS TC), go to http://www.oasis-open.org/apps/org/workgroup/emergency/members/leave_workgroup.php.
