Initial Steps
Project initiated by rSmart
Input from Academic Technology @ Marist
Wiki Capabilities
3

Goals and Requirements
4

Evaluation and Selection
Improve rWiki
Identify a wiki (looked at over a dozen wiki products)
Integration (loose versus tight)
Source code development language
5

Iterative Process
Resulted in selecting XWiki
Met key feature requirements
Good support
Java, with REST and RPC options
Loose integration
Uses XWiki rendering engine within iFrame
Sakai driven users, groups and roles
Reasonable set of tool functionality needed
Customization
6

Reaching out
7

Engaging others
Sent & Reviewed Evaluation Document with rSmart
Started a confluence page on Sakai
Notified Sakai List groups
Notified XWiki developers
8

Development Process
9

A RESTful Approach
We choose REST:
XWiki REST API provides access to all resources and to creating and managing users and permissions.
Easy to develop and flexible
10

Site-level Users, Roles, Permissions
Tool allows explicit pushing of Sakai Users to XWiki
Set permissions for Sakai Roles
Add new XWiki users
Add new Roles/Group
11

Site Configuration Menu
12

Page-level Permission
Set page permissions (XWiki) for roles and groups (Sakai)
Exposes XWiki’s more granular permissions
13

Page Configuration Menu
14

Wiki Pages
Select and work with a Wiki page
Exposes as little or as much XWiki functionality as desired
Uses stylesheets and velocity to skin pages
Can expose edit page, comments, annotations, attachments, history and more
15

Wiki Pages
16

Manage Wiki Pages
Add, Edit, or Delete pages
Uses FckEditor
17

Manage Wiki Pages Menu
18

Revisiting Development
19

Too RESTful
Getting user permissions requires…
20
getAllUsers
AllUsers
Iterate
thru All
Users
getUserPermissions
UserPermissions
XWiki Tool
XWiki

Too RESTful
Similarly, for a given page’s objects …
21
getPageObjects
PageObjects
Iterate
thru Objects
getObjectAccessRights
ObjectAccessRights
XWiki Tool
XWiki

RPC
Decided to use XWiki RPC
Improved performance
Two RPC clients (XWiki and Apache)
RPC support waning
22

Testing
Built and deployed with Sakai 2.7.1 and rSmart-CLE-2.7.1
One server running Sakai, XWiki, MySQL
Academic Technology performed initial tests (ongoing)
23

Moving ON…
24

Other Enhancements
Sakai group aware
FckEditorv.s. XWiki Editor
Configuration properties
25

Current State
Getting it out there:
Updates made to Confluence
Submit to Contrib
Inform community
26

Next Steps
Add support for Sections
Additional Testing
Consider Integration with other tools (e.g. Assignments)
CkEditor
Integrated Search between Sakai & XWiki
Internationalization
SPI Layer
27

Future Considerations
Collaborative editing
Semantic search, tagging, views
28
