ssb-wikimedia

Wikimedia to Secure Scuttlebutt bridge. Sync revisions from Wikimedia pages into SSB.

CLI

Usage: ssb-wikimedia-sync [-y] [-n] [-h] [<url>...]

Options:
  -y  Yes mode. Publish messages without prompting for confirmation.
  -n  Dry run. Output message draft JSON instead of publishing them.
  -h  Help mode. Output usage text and exit.

If URLs are not given on the command-line, they are read line-by-line from a file in the SSB directory: ~/.ssb/wikimedia-pages.txt
Lines in that file starting with "#" are considered comments and skipped. Blank lines are also skipped.

Schema

type: wikimedia/revisions

The message content is as returned from the Wikimedia Query/Revisions API, with the following change:

• Message type is added.
• Property "site" refers to the Wikimedia site base URL.
• Property pageId is a denormalization used to facilitate querying SSB for an article. It is the SSB blob hash of the values for the site property and title property, separated by a tab ("\t").
• Content ("*" property in revision slots) is replaced with the id of the SSB blob containing that content, at property "link".
• Property "parents" is an array of links to the latest previous message(s) of the same type for the same page containing previous revisions to the page. Any revision parent id referenced from the current message should be found in the current message or a message referenced in this parents array.
• Property "userId" is added to each revision object. It is computed the same as pageId but for the User page of the revision author.
