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 href="http://product.itoworld.com/map/6" target="_blank">http://product.itoworld.com/map/6</a><br>
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 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 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>

We've a few of way's of counting how many people are
involved with the quarterly project to map schools. As
such I have updated the wiki to focus on comments
rather than the raw numbers (e.g. which areas are you
mapping, how else are you helping). Feel free to
update.<br>

<div>By features we've mapped nearly 1250
schools as ways, removed nearly 1000 schools
mapped as nodes (either converted to a way or
removed duplication). Overall that is 250
"new" schools mapped. This is a minimum as I
don't know how many of the 1000 nodes removed
were duplicates.<br>
