Description
RtWiki is a Realtime Collaborative Editor for XWiki Syntax and scripts based on the cjdrt Realtime Engine and the XWiki WebSocket Integration extension.
In contrast to the RealTime Wiki Editor which is based on the Jupiter Operational Transformation Algorithm and implemented in the Google Web Toolkit, RtWiki is based on a radically new peer-to-peer design implemented entirely in Javascript and based on the Bitcoin Blockchain. While the Jupiter Realtime Editor had issues such as poor performance with large pastes, its fundamental limitation was its inability to handle multiple types of content because the server had to be aware of the content type. This realtime editor is based on RtBackend which is unaware of the document's content and merely handles registrations, de-registrations and the forwarding of messages, much like a chat server.
The RtWiki editor preserves the user interface of the original XWiki Wiki editor so with the RtWiki editor, you can smoothly transition from editing Wiki syntax alone to editing with other collaborators as a group.
If a document is currently being edited in Realtime, the normal "This document has been locked for editing" screen will appear but will allow you to join the Realtime Collaborative Session if applicable.
And of course if you are uncomfortable with realtime editing, you can click on the ALLOW REALTIME COLLABORATION checkbox to return to normal editing at any time and your preferences will be preserved.
Prerequisites & Installation Instructions
We recommend using the Extension Manager to install this extension (Make sure that the text "Installable with the Extension Manager" is displayed at the top right location on this page to know if this extension can be installed with the Extension Manager). Note that installing Extensions when being offline is currently not supported and you'd need to use some complex manual method.
You can also use the following manual method, which is useful if this extension cannot be installed with the Extension Manager or if you're using an old version of XWiki that doesn't have the Extension Manager:
- Log in the wiki with a user having Administration rights
- Go to the Administration page and select the Import category
- Follow the on-screen instructions to upload the downloaded XAR
- Click on the uploaded XAR and follow the instructions
- You'll also need to install all dependent Extensions that are not already installed in your wiki
After installing with the Extension Manager, you will need to open the WebSocket Port as described above and restart the XWiki installation.
