[OSM-talk-ie] Typos in Townland names

Thanks for the OSM OSI comparison map, this is great for showing up
mistakes in the townland boundaries and I even found a missing townland or
two.
This umap seems pretty cool too. I notice that many townlands without
logainm tags are because of the typos. Fixing those should allow the script
to do its thing. I can see a CP with a typo in it's name and because of
that, none of the townlands in it have logainm tags yet.

I have a question about the logainm script, How can it handle a barony that
crosses a county border? For example, Barony of Ross crosses the
Galway-Mayo border as one relation. This relation has one logainm tag for
Ross in Mayo (logainm:ref = 172) but there are separate loganim ref numbers
for Ross in Galway (logainm:ref = 85) on the logainm website. Can we
somehow add both ref numbers to the Barony relation? something like
logainm:ref=172;85, or what do you suggest? It seems that the script
assumes everything is nested inside counties but if baronies/civil parishes
cross county borders, then they have two logainm ref numbers.
