[wsia] On Transient Thingies

Eilon,
As it relates to joint interfaces WSIA-WSRP discussions, this brings up
a "persistent" point (no pun intended), that is being pursued in the
Customization Use Case- you have created the beginnings of a mapping
from business need/objective to business requirement to derived
requirement.  Perhaps we should look at some of these more complex
issues and go back to the scenarios to help us in this discussion
process.
 
I think it would enhance our results and also help us focus on what is
required.
 
Other suggestions welcome.
 
Thank you.

	Hi All,
	 
	Here's an example for the need for Transient Thingies in the
WSIA world, based on the MapQuest scenario.
	 
	If a hotel chain wants to provide a search capability on their
Web site, namely allow the user to enter a city and display the list of
hotels.
	 
	And if the hotel chain wants to display alongside with every
hotel found (suppose 7 were found) also the map of that particular
hotel.
	 
	And assuming that the size of that list is variable (could be 1
hotel found or 50).
	 
	Then it would be quite inappropriate to use Persistent Thingies
for each one of the 50 list results. (And manage them).
	 
	Rather, the WSIA model in this case should be a single
Persistent Thingy, but the Consumer (in this case the hotel chain) can
create multiple occurrences of that Persistent Thingy, namely: multiple
Transient Thingies, and provide the Nth Transient Thingy with the
appropriate location data that corresponds to the Nth hotel - probably
using property values or otherwise using out-of-band operations.
	 
	In this case, even though the 50 elements come from a single
service, might have a single session (it's all the same user), they
would still need a per-transient-interaction element, what we call the
Transient Thingy, to differentiate between them.
	 
	Cheers,
	Eilon
