I have modified my "name equality rule" to consider "N" equal to "North"<br>
etc., also it will ignore case, whitespace, and as before the usual<br>
street type expansions (St->Street etc).<br>
<br>
This brings the number of problematic objects down by around 5500, and<br>
practically all of them are in the US. However, I noticed that I forgot<br>
to account for "Saint"->"St", and will re-do the numbers yet again<br>
before publishing an updated list.<br>
<br>
I think the best course of action would be:<br>
<br>
1. Wait a while, until various communities (potentially pointed to this<br>
conversation via the widely-read weekly new roundup) have had the time<br>
to check whether my automated assessment of which names count as<br>
"contributed" by chdr is correct. Mikel has found the issue above and I<br>
fixed it; it is quite possible that there are others.<br>
<br>
2. Run the redaction, and remove all names contributed by chdr. At<br>
present it looks as if less than 10% of these objects had a different<br>
name before; more than 90% had not name at all. Perhaps it is indeed<br>
best to remove the name in these cases as well instead of reverting to<br>
the old name.<br>
<br>
3. Load the IDs of all affected objects in a MapRoulette task or<br>
similar, so people can check the names by survey, or from different<br>
sources. (I assume that, as Simon pointed out, open data will not be<br>
available for all countries affected. I fear that, with MapRoulette<br>
geared towards armchair mapping, there might be a temptation for people<br>
to yet again fill in the blanks from inadmissible sources. Maybe we<br>
should limit the use of MapRoulette to countries where we know that open<br>
sources exist, and use fixme tags or notes for other countries?)<br>
<br>
I think that would be cleaner than verifying the names ahead of time.<br>
Also it would create an audit trail - from the object history, you could<br>
then see that the name was removed for copyright reasons, and you could<br>
then see that user XYZ has added a new name. If it should later turn out<br>
that this name was also copied from an indadmissible source, we know<br>
that user XYZ is at fault, whereas people creating lists with<br>
independently verified names is not something that would give us such a<br>
recording.<br>
<br>
I must apologize for not having given a time frame in my initial email;<br>
there's absolutely no reason to panic. This matter has been sitting idle<br>
for years, and a few more weeks won't kill us. We can sort this out<br>
calmly and then do the right thing.<br>
<br>
Bye<br>
Frederik<br>
