[Jeremy]<br /></p><p><br /></p><p>from my notes of the discussion about BoM's SitesDB at the ad-hoc meeting in Melbourne:<br /></p><p><br /></p><p>"Systems … multiple systems at a station … [WIGOS MD doesn’t have “systems” … in WIGOS MD one navigates from “station” to the observed quantity kind and then to the particular equipment|sensor|instrument used to capture that quantity kind] … examples: a sonic anemometer can measure three quantity kinds, (i) wind speed, (ii) wind direction and (iii) air temperature … whereas measurement of humidity may require two instruments, (i) wet bulb thermometer and (ii) dry bulb thermometer … in this case the two instruments working together might be considered to be a “system""<br /></p><p><br /></p><p>...<br /></p><p><br /></p><p>It may be pertinent to add a self-referential relationship to the EnvironmentalMonitoringFacility with source and target roles of "system" and "sub-system" allowing a particular 'facility' to be decomposed into the sub-systems from which it is comprised?<br /></p>
