1) Working with Yahoo
	Yahoo classifies information hierarchically such as
	Education --> K-12 --> One of Many States --> One of many School Boards --> School --> Category of interest in School
	
	In GXOS this becomes
	//Education/K-12/Florida/Leon County/Chiles/Courses/Grade/... list ...
	List in Yahoo is typically a list of URL's with some text comment
	Each Item can be viewed in different ways. GXOS allows Rendering
	choice to depend on user and client device and information
	Sometimes list is user dependent such as in list of cities where
	you want weather to be displayed or in list of stocks that you want
	quotes for. Such a list would be a stream in GXOS

 So you can say either Yahoo is a natural engine for Yahoo or vice versa
 GXOS is a collaborative portal which could be used in premium Yahoo Services
 GXOS automatically stores all metadata Yahoo needs and indeed generalizes
 
 Note that in learning application of GXOS, we would store curriculum in Yahoo like
 hierarchical model showing how Yahoo engine can support new revenue (education
 revenue stream) stream
 
 Currently Yahoo updates its "structure" server side (e.g. user changing preferences
 for some list ot other or Yahoo staff updsating portal content). This is very
 easy to make collaborative i.e. to build Yahoo sharedlet is easy 
 There are two implemenations
 a) GXOS runs Yahoo like services. Then sharedlet is generic server side updste
    We don't have this yet but it is trivial
 b) Yahoo runs Yahoo services. Then Yahoo must supply to GXOS the
 "event" -- Such and such Information updated

2) Generalization
	You can look at Amazon and other commerce sites and see similar structures
	Couple of important types of Collections to consider are:
	a) Collection created dynamically by searching archives e.g. get me all books
	   authored by Tom Clancy
	b) Type of list you get when you design your computer online as at Dell Site
	   This would be specialized set of properties specified by XML Schema 
	   "dellcomputer"

3) Types of Interaction
	a) Teacher/Students with Yahoo as Curriculum
	b) Shoppers/Information Seekers sharing/customing things like your new Computer
	

4) GXOS Model
	Interpreter reading XML Messages which generalizes Shell of UNIX.
	i.e. there are cat copy grep etc uitlities
	
	GXOS Object data sits in data user labelled by GND labels which
	are indexed in database
	Selected other properties indexed but most of XML properties are
	"just" interpreted at runtime.
