questions about setting up SOS

[John Cartwright]

Hello All,

I'm trying to understand how to configure a mapfile to serve data out of 
Oracle Spatial using Mapserver's SOS_SERVER and am a little confused 
about the relationship between the sos_procedure, 
sos_observedproperty_id, and sos_offering_id. 

It looks like the sos_procedure and sos_observedproperty_id must be 
unique to each layer in the mapfile.  So if I have a system of buoys 
that each measure temperature and salinity, would I define two layers 
pointing to the same spatial data and sharing the same sos_offering_id 
value?

Thanks!
