You might want to consider a canonical model for observations here - its basically a model for metadata for results of observations :
https://www.w3.org/TR/vocab-ssn/ where sosa:Observation is a meta object about the value of a property it needs to be married to a canonical model for measurement (uom) as well as for observable properties you could probably entail reified statements or simple properties against the "feature of interest" - i.e. subject - from the ssn/sosa model - maybe declaring sosa:featureOfInterest, sosa:observedProperty and sosa:hasResult to be subproperties of rdf:subject, rdf:predicate, rdf:object would be sufficient to do this in EDG? This normalises patterns for observation time, procedure etc. I'm interested in formalising profiles of SOSA - and a formalisation of it as a reification pattern might be an interesting idea if it has utility.
