Well, the query seems good, and I will try to do more in this lenguage.
I have another question, I get the result in JSON or CSV format, and then
the URL "http://www.wikidata.org/entity/Q8660" goes me to another page with
city information.. Can I obtain this information in XML format or JSON? In
this way I could parse all the attributes and get the most interesting for
me.
Thanks,
Guillem

Hello Guillem,
You are probably looking for something like
https://www.wikidata.org that
is a Wikipedia sister project.
It provides nice APIs for use cases like yours:
https://www.wikidata.org/wiki/Wikidata:Data_access
See for example

Hello, my name is Guillem and I'm a student that I'm working in Liquid
Galaxy project, and now I have some questions and doubts that I would like
to resolve to continue with the project.
I have been working with WIkimedia API, I found some information about
it and I
tried diferent actions to get responses and compare. For example,
in my case I want to obtain the most populated cities in the world.
xml&titles=List_of_cities_proper_by_population&prop=
revisions&rvprop=content " (in this page there are a list of most
populated cities in the world)
The response is all the Wikipedia page, and the
information text is
inside <rev> tag. Then, my task is to parse the text
response and obtain
the cities name in the list. I would like to know if ther are some
posibility to obtain only the cities list, and it will be more easy to get
it.
Once I have the names of the cities, the next step is to obtain the
coordinates
for each one. Here I have two possibilities: a new query with
API ("
https://en.wikipedia.org/w/api.php?action=query&format=
xml&titles=Shanghai&prop=revisions&rvprop=content ") I put the city
name
in the parameter "title", and then the response is so extended, but I get
only the Infobox part to obtein the mainly information about the city.
And the second option is to use bdpedia, I find
this option searching
and it also can be a posibility, but my doubt is: when I
search "
dbpedia.org/data/Tokyo " the properties and values are the same in the
wikimedia page for the city? I have discoverd that I can obtain the
response in json or xml format.
In this way, I could get some information about
the city, and search for
each tag or property that is well identified.
I haven't found the way to obtain more detailed some information about
in this
case a city (I would like to have the mainly information
organizated in tags and then it will be more easy to obtain the results).
So, the other option is to do the proces that I have explained, this
requires more work but also will be valid.
Thanks for you time
your sincerely,
Guillem.
