Dear all,


Could someone on this mailing list explain me the right method to extend
the UAProf schema adding new identified attributes?


For example we let consider this case: we need to define a new schema
that is identical to the UAProf schema apart the new attribute
IntegratedVGACamera that must be added to the UAProf HardwarePlatform

So we have defined the new schema in the following way:



1.	-
226##>  <rdf:Description rdf:ID="IntegratedVGACamera">
2.	<rdfs:comment xml:lang="en">Description: Indicates whether the
device supports integrated VGA camera. 
3.	Examples: "Yes", "No"
4.	</rdfs:comment> 
5.	<rdfs:label xml:lang="en"> IntegratedVGACamera </rdfs:label> 
6.	<rdf:type
rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#Property" /> 


7.	<rdfs:domain
pschema-20030226#HardwarePlatform" /> 
8.	<rdfs:range
schema-20030226#Boolean" /> 
9.	<prf:ResolutionRule
10.	</rdf:Description>




In the line number 7. we have a reference to the HardwareComponent of
the UAProf schema. This is made for not redefine inside the new schema
all the Component included the HardwarePlatform.

What do you think? Is this approach correct or we must redefine also all
the existing UAProf Componet in our new schema ?


Thanks in advance for your help
