Hi Yaroslav,

I think that expanding the image tree makes a lot of sense. However, perhaps it makes more sense to expand from Buildings in Middelburg - then to streets - then to houses. It would make more sense to me to have a category "Buildings in Middelburg", "Buildings in Lange Noordstraat, Middelburg" and then "Lange Noordstraat 23, Middelburg". In very big cities, you might want to add a layer of city-areas (in Amsterdam for example). 

However, I don't know what would be a useful threshold to create a category (both for streets and per building) - perhaps a more experienced Commons user can make a useful suggestion to that. My gut feeling would be that we would only create categories for five or more images, but I can be wrong there.

I am sorry, apparently I misunderstand smth.

Let me give an example.

I uploaded yesterday this file:
http://commons.wikimedia.org/wiki/File:Middelburg_Lange_Noordstraat23.jpg

It is included in the categories on Commons which were automatically
produced by the WLM template or by other templates present. All of them are
hidden.

* Rijksmonumenten with known IDs
* Media with locations
* CC-BY-SA-3.0-NL
* Self-published work
* Images from Wiki Loves Monuments 2011
* Images from Wiki Loves Monuments 2011 in the Netherlands
* Uploaded with UploadWizard

On top of that, when I was uploading the file, I added one more category:
* Rijksmonumenten in Middelburg

(otherwise the file would be included in the default category
Rijksmonumenten in the Netherlands). This category is not hidden and is
included into a number of other categories, including Middelburg.

I know that the same monument has at least two other images, and I only
know it because I uploaded them myself:

http://commons.wikimedia.org/wiki/File:Middelburg_Lange_Noordstraat23_Right.jpg
and
http://commons.wikimedia.org/wiki/File:Middelburg_Lange_Noordstraat23_Left.jpg

In my opinion, this justifies the creation of the category smth like Lange
Nordstraat 23, Middelburg (or Rijksmonument 29175, which is the same),
which I will create in October, once the uploading rush is over.

However, I have no idea whether anybody else uploaded images of the same
building, because they would need to land in the same category. (It could
also have happened that these images do not even have a monument ID
template, but this is a different story whatsoever).

The question in my prospective was whether we have a tool which would able
to tell me that (i) there are multiple images of RM 29175, located at Lange
Noordstraat 23, Middelburg, and (ii) there is no category Lange Nordstraat
23, Middelburg or equivalent. I am not sure though such a tool could be
created. May be (i) can be done by bot and (ii) then manually.

Cheers
Yaroslav
