Parser 2011/Real-time collaboration

Jump to navigation Jump to search

People interested[edit]



  • Could greatly enhance community bonds by allowing mentors and newbies to edit together
  • Get to consensus faster when editing an article
  • More of a social space
  • Especially good for focused groups like WikiProjects that depend on small numbers interacting intensely
  • Most groups who need to collaborate fast already use Google Docs or Etherpad or some such; (the WMF does a lot already) which makes translation to public wiki form tedious. This could bring them back to public wikis
  • Remove all Edit Conflicts


  • Wikitext is not just formatted text, has embedded templates, parser functions, etc. etc.
  • MediaWiki's model is one user : one edit.
    • Could resolve this by creation sessions owned by a user, having others join, then adding other usernames to commit comment
  • If combined with visual editing, can make the software stack even more complex.

Relevant concepts[edit]


Believed to be interesting enough to explore, not officially on the agenda.

Mark Holmquist posted to the wikitech-l list announcing a test instance of MediaWiki with an experimental extension enabling this feature: [1]

Code repository[edit]



  • 2011 Spring - Trevor & Neil picked the brains of people who did w:Apache Wave (neé Google Wave), w:Etherpad, and more. Their concepts have already influenced some of Trevor's experiments, particularly annotated text over DOM-like hierarchical nodes.
  • 2011-04-21 - Talked to Etherpad-fork startup Hackpad - meeting record
  • 2011-05-05 - 2011-05-06 Hackpad engineers work in WMF offices with Neil, create quick demo of Hackpad as a host for an editing session, via a user script.
  • 2011-05-10 - Project posted on Wikitech-l by Neil and Hackpad blog
  • 2011-05-15 - Neil gives lightning talk at Berlin Hackathon
  • 2011-06-23 - Defining user stories, deliverables
  • 2011-07-01 - Neil has local etherpad hostable, needs help making the Hackpad hacks work



  • WikiEducator has CollabOERate gadget up and running, based on Mozilla's TogetherJS. Requires "modern browser" (perhaps does not work with IE?)
