    Unsure what two queries you want to compare, but OT does allow
    difference comparisons by first saving each query result to a
    variable:<br>

    This returns all edits from the last day that weren't by me.
    Obviously you'd need to change it to your user name to see any
    results & you can vary the day/hour.<br>

          1) I think isced:level is really helpful, as I've known people
          wanting a list of "all primary schools nearby" for various
          jobs. Is there a map/list that shows schools with that tag or
          not? Maybe something like ITO World's maps?<br>
          1b) Ah, they have one for name/no-name, might be good to
          request isced:level there too (or if it has the ID). <a

          1c) I'm being silly and forgetting how easy Overpass API is
          now. But it doesn't allow two queries at once and to visually
          compare the difference. <a moz-do-not-send="true"
            href="http://overpass-turbo.eu/s/e7o" target="_blank">http://overpass-turbo.eu/s/e7o</a><br>
          <br>
          2a) What tag are people using for the ID?<br>
          2b) Presumably the only way to get the/an ID is from the <a
            moz-do-not-send="true" href="http://gov.uk/" target="_blank">gov.uk</a> data?
          It's copyright doesn't allow use, but perhaps using it for the
          ID is okay? So far this quarter I have been using OS
          StreetView or googling for a website as a name source. As a
          result, all the schools I've edited/added in the last month
          have a "website" tag.<br>
          <br>
          Btw, County Durham is very annoying. Since maybe 3 years ago
          they have been combining schools (juniors & infants into
          primary, or two villages now having 1 school to share, plus
          all the academy-type name & management changes). Probably
          a good time for this enjoyable project then! Meanwhile my
          landlady's job involves visiting schools all over the county.
          Anyone got a long lasting camera & a GPS logger I can
          secretly strap to her car/bag?<br>
