<DIV><FONT size=2>>I would like to talk about the location of the person
making the search versus the location of the product or service provider. If I
search for a product and I want it now, I only want a list of provider in a
distance applicable for my request. And if I go to Europe this summer and want
to make reservation or search for activities occuring at that time, the 'where I
am' specification change. If I have a secondary house and make request on the
week-end, I want the restaurant in that region and not the one near my primary
house. An identity profile should be include in the query and give the chance to
the search engine to make a better choice in regard of my age, sex,
etc...</FONT></DIV>

<DIV><FONT color=#000000 size=2>Interesting. Some of the issues with
product location are:</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT size=2>1. How to indicate location?</FONT></DIV>
<DIV><FONT size=2></FONT><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Address or map coordinates? How does one find map
coordinates? What happens when he moves?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>2. How to associate location with products?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>If a vendor has all inventory at a single location then the
location can be #FIXED in his DTD. If inventory is distributed around the
globe, each product or inventory group will have to be marked. The problem
is that now it makes no sense to indicate physical location. It will have
to be a store code which causes problem with search services since store codes
will have to be converted into location format used by the search
service.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT color=#000000 size=2>As far as time constraints go, each product will
probably be marked with time. The problem is that some time constraints
are relative in nature.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>*Ouch* I just thought of another painful
problem with prices. What happens when a store wants to put on a
sale? His database of products will have to map to different pricing
schemes constrained by time, location, or association.</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT> </DIV>
<DIV><FONT color=#000000 size=2>All this hurts my head a bit but it is very
interesting indeed...</FONT></DIV>
