Realtime

Tiki has historically been mostly an asynchronous collaborative tool, except for Live Support and Chat. Since Tiki5, for real-time collaboration, Tiki offers an integration with BigBlueButton (Audio/Video/Screensharing/WhiteBoard/Chat).

This page is to discuss options to make several features realtime:

• Docs (ODF documents via WebODF)
• Wiki
• Drawing (SVG-edit)
• Spreadsheet (jQuery.sheet)

Will be useful along with BigBlueButton collaborative sessions. Ideally for Tiki, it would be the same approach (ex.: library) for all four (and any future) features. And we could take this opportunity to revamp Live Support and Chat (which work OK but are not the most recent technology)

Options

BigBlueButton

One possibility is to go the BigBlueButton route.
Benefits:

• Already integrates with Tiki
• it would be via Shared Notes

Drawbacks:

• Add BigBlueButton as a requirement
• Flash
• Likely less general interest than a JavaScript solution

Etherpad Lite

Another possibility is integrating with Etherpad Lite

Benefits:

• Already active project

Drawbacks:

• Adds Etherpad Lite as a requirement
• Overlap with some of Tiki's wiki functionality
• Will it be easy to port to Spreadsheet, Drawing and Docs?

A JavaScript library

Benefits:

Drawbacks:

WebRTC

• WebRTC

• Synchroedit: SynchroEdit is a browser-based simultaneous multiuser editor, a form of same-time, different-place groupware. It allows multiple users to edit a single web-based document at the same time, and it continuously synchronizes all changes so that users always have the same version. http://www.synchroedit.com (LGPL & MPL)
