[Talk-ht] Please, please attribute your sources

[David Fawcett]

David,

Thanks for the reminder to the list.  I have been in the same exact
situation while trying to improve the streets data.

Based on the DMA topos, you know what the name was ~15 years ago, but
it could have changed.  Is the existing name in OSM based on UN or
local data, or did the mapper just accidentally use 'Rue' in place of
'Ruelle'.

It definitely decreases productivity on tasks that need to be done quickly.

David.
