Project Updates
Beyond Sakai 2.6
Kernel
Minor and Maintenance Releases
Tools Statuses (Core/Provisional/Contrib)

33
Releases
• Maintenance Branches
– Continue no new feature policy
– Improve documentation of practices
• Maintenance Releases
– No longer branched directly from maintenance branch
(e.g., 2.5.x)
– Based on changes in a limited subset of components
• Minor Releases?
– What features would be appropriate?
34
Tool Status
• Core/Provisional/Contrib
• Key Questions:
– What goes in a release?
– How capable is a tool?
• A small team to decide what goes in a release
– Similar in scale and scope to those already participating in the
Release Management WG?
• Tool and Service Scorecards
– Provisional Criteria, Supported Criteria
– Key Areas: Community Support, Technical, User Experience,
Documentation
35
Subversion and Maven
• Technical Management of Source and Release
• mSub – Massively inclusive Subversion
–
–
–
–
Facilitate sharing of customizations
Increase ease-of-contributing to trunk
Simplifies organizational merges
No artifacts
• Versioning
– Remove M2
– Snapshot – next versioned release of Sakai (e.g., 2.5.1SNAPSHOT)

–
Many focused on “page” authoring
WYSIWYG editing/in-place editing
Coupling and creating things other than Resources
Next steps: identify common problems (use-cases) and potential
collaborators (new WG coming…)
37
Internationalization
•
•
•
•
•
•
•
•
•
Add debugging locale to verify localization coverage
Email Templating and localized email notification
Lower barriers for translation (Translation Server!?)
Need to focus on I18N bug fixes, then enhancements
Need a consistent UTF-8 QA Server (Japan/Nagoya)
QA: verify date issues on more than one QA Server
QA: Need servers with both UTF-8 & Email (IU, …)
Automated Code Reviews for common l10n errors
Sub-locale translations (e.g. K-12 vs Collegiate)
38
Static Code Review / Large-scale Sakai
• Best Practices for Code Review
– Encourage Peer Review/Pair Review
• To Do’s:
– Alan Berg and David Haines: propose
“SakaiBogoBug” metric for the scorecard
– Further discussion on global commit rights to address
specific Bug Report issues
39
Kernel
• GoogleDoc: http://docs.google.com/Doc?id=dp3hj8r_9fz2mrkdz
• Proposal for a Kernel 1 and Kernel 2
• Kernel 1 – Repackaging
– Dec 2007 Release Candidate 1
– ~2 months work to finish
• Kernel 2 – Refactoring and Reengineering
– Document requirements
• Timelines
–
–
–
–
Kernel 1 Freeze: 4 months prior to Sakai 2.6 code freeze
Kernel 1 Ship: 2 months prior to Sakai 2.6 code freeze
Kernel 2 Freeze: 4 months prior to Sakai 3.0 code freeze
Kernel 2 Ship: 2 months prior to Sakai 3.0 code freeze
• Work could proceed relatively simultaneously
