Hi Giovanni, The pagelinks table is great for temporal snapshots: you know about links between pages at the time of the query. Parsing the wikitext is needed to provide an historical view of the links :) Cheers Joseph

Thank you Joseph; great to hear there is interest in building such a dataset. You say that the link information would need to be parsed from wikitext, which is complicated; would the pagelinks table help as an alternative source of data?

Hi Giovanni, Thank you for your message :) You are correct in that there is no information on page-to-page link as
of
today, as well as no information for instance on historical values of revisions being redirects for instance. We share with you the idea that such information is extremely valuable,
and
we have in mind to be able to extract it at some point. The reason for which it has not yet been done is because those pieces of information are only available through parsing the wikitext of every revision, which is not only resource intensive but also complicated technically (templates, version changes etc). You can be sure we will send another announcement when we'll release that data :) Best,

Hi Joseph,
Thanks a lot for creating and sharing such a valuable resource. I went through the schema and from what I understand there is no information
about
page-to-page links, correct? Are there any resources that would provide such historical data?

Hi Analytics People,
The Wikimedia Analytics Team is pleased to announce the release of
the
most
complete dataset we have to date to analyze content and contributors metadata: Mediawiki History [1] [2].
Data is in TSV format, released monthly around the 3rd of the month usually, and every new release contains the full history of metadata.
The dataset contains an enhanced [3] and historified [4] version of
user,
page and revision metadata and serves as a base to Wiksitats API on
edits,
users and pages [5] [6].
We hope you will have as much fun playing with the data as we have
building
it, and we're eager to hear from you [7], whether for issues, ideas
or
usage of the data.
Analytically yours,
-- Joseph Allemandou (joal) (he / him) Sr Data Engineer Wikimedia Foundation

[3] Many pre-computed fields are present in the dataset, from
edit-counts
by user and page to reverts and reverted information, as well as time between events. [4] As accurate as possible historical usernames and page-titles (as
well
as user-groups and blocks) is available in addition to current
values,
and
are provided in a denormalized way to every event of the dataset. [5] https://wikitech.wikimedia.org/wiki/Analytics/AQS/Wikistats_2 [6] https://wikimedia.org/api/rest_v1/ [7]
