MediaWiki APi doubts Liquid Galaxy Project - Mediawiki-api

8 Mar 2017

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.

First of all, my query will be:
" https://en.wikipedia.org/w/api.php?action=query&format=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=xm
l&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 <http://dbpedia.org/resource/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.
