Hi all.
Firstly, apologies for eventual duplicates or posting the question in the wrong mailing list.
Secondly, could anybody kindly explain to me if some Wikipedia pages changed their IDs from the past ? Or if so point to me where this might be documented ? I have Wikipedia pages-articles XML dumps from the years 2006 and 2008 and when I was parsing those dumps I ran across some situations such as the following one. In the dumps from 2006 and 2008 I found that the South Africa page has the ID 68854, while in the most current Wikipedia pages-articles XML dump (i.e. 2016) the same article has the ID 17416221. I am trying to match some Wiki pages by IDs across time, but the example above is not helping.
Much appreciated in advance for any help.
