Hello Eric, so we don’t have any tag or field in the add/changes dump that
differentiates between “new pages vs pages with new revision”. But we have
a column in the page table called “page_is_new” and we dump that table
twice every month in SQL format. You might want to cross-check the page
table dump against the add/changes dump of the same day;
Please note that both dumps are not done at exactly the same time and the
data on both files might not be consistent.

Hi Ariel,
Thank you for the detail! Helpful to understand.
Is it possible to disambiguate completely new pages vs. pages with new
revisions in the "Adds/changes dumps"? Looking at nodes in the XML I'm not
sure there's a way to do this.
In the interim I wrote a golang script that parses a meta-history file as
previously described, with various filters – excludes redirect pages (wow
there so many), user pages, etc. It worked out rather well. A bit sloppy
but here is the script

reference.

Eric,
We don't produce dumps of the revision table in sql format because some
of those revisions may be hidden from public view, and even metadata about
them should not be released. We do however publish so-called Adds/Changes
dumps once a day for each wiki, providing stubs and content files in xml of
just new pages and revisions since the last such dump. They lag about 12
hours behind to allow vandalism and such to be filtered out by wiki admins,
but hopefully that's good enough for your needs. You can find those here:

Hi,
I am interested in performing analysis on recently created pages on
English Wikipedia.
One way to find recently created pages is downloading a meta-history
file for the English language, and filter through the XML, looking for
pages where the oldest revision is within the desired timespan.
Since this requires a library to parse through XML string data, I would
imagine this is much slower than a database query. Is page revision data
available in one of the SQL dumps which I could query for this use case?
Looking at the exported tables list
<https://meta.wikimedia.org/wiki/Data_dumps/What%27s_available_for_download#Database_tables>,
it does not look like it is. Maybe this is intentional?
Thanks,
