Also, let's remember that a resource could also be the value of a property, and that is not always the case that URI can be found in a xlink attribute. For example: Resource = System, which identification could be the URL of the SensorML instance Property = Procedure Type Value = URI in the sml:value <sml:classification> <sml:ClassifierList> <sml:classifier name="System Type"> <sml:Term definition=" http://www.w3.org/1999/02/22-rdf-syntax-ns#type"> <sml:value> http://mmisw.org/mmi/20080529/sensor.owl#CTD</sml:value> </sml:Term> </sml:classifier> </sml:ClassifierList> </sml:classification> And, I think SensorML and other specs in SWE are not fully compliant with GML. -luis > If this is not correct, or the wording is awkward, please point us in the > right direction.
