Sakai 2. 5 Highlights • • Many minor bug fixes and tweaks all around Framework and Services Tools Cross-Project Activity Highlights

Framework and Service Highlights • Content Review – Minor changes in APIs and to integration with Assignments; only applicable to sites running a content review implementation (e. g. , Turnitin). • User Directory Service – Improved performance when retrieving provided users. – Support for login IDs (for Kerberos authentication, for example) which differ from user EIDs. – Optional short-term authentication caching to greatly improve DAV performance. – Can now enable or disable User Directory Provider implementations via the sakai. properties file. – Reduced number of required methods in the User Directory Provider interface.

Framework and Service Highlights • Database – Addition of a faster lower memory footprint entity parser based on SAX. – Addition of an optimized binary entity serialization. • Memory Service (should be under framework) – Centralized management of Hibernate Cache provision. – Replacement of Memory. Service cache with ehcache in preparation for cluster wide cache optimizations. – Upgrade to ehcache 1. 3 to enable JMX capabilities.

Tests & Quizzes (a. k. a. Samigo) • Promoted from Provisional to Core status. • Allow ability to move/copy/remove multiple questions to other pools. • Allow ability to adjust score in edit assessment screen. • Allow ability to remove published assessments. • Add event logging for user operations. • Allow copying of all questions in a part to a selected pool. • Allow students' responses to be exported to Excel. • Allow point values of questions to be reset when a random draw from pool part is created; all questions from the pool are copied to the part.

Help • Support for help content in multiple languages. – No longer require restart? • Added sakai. properties setting to hide help collections. • Added tool registration property to register additional help collections. • Updates to help content from Indiana University (IU) Knowledge Base for 2. 5 functionality (as provided by project leads and IU KB team).

Citations Helper • Import citations in RIS format from other tools such as Ref. Works and Endnote. • Sort citation lists by author, title, or date. • Search for and embed citations from within the WYSIWYG Editor (FCKeditor); similar to Twin Peaks.

Messages and Forums • Message. Center previously split in 2. 4. • Messages – Ability to bulk Move and Delete Message. – Ability to forward Messages. • Forums – Ability to delete forum messages. • Added synoptic views for Home.

Poll • Minor UI improvements: – rich text editor – date picker widget • Improved data validation.

Portal • Addition of site categorization. • Addition of tool categorization. • Improved experimental i. Frame-less tool presentation (a. k. a. PDA portal)

Schedule • Performance improvements to reduce memory load of schedules with a large number of items. • i. Cal subscription export service and import; reoccurring events are not yet supported. (ical. experimental=true)

Resources • Replaced dropdown widget for Add and Action menus with an accessible one. • Improved performance by rewriting underlying Storage of entities to reduce memory usage and CPU load, • Refactoring of database to eliminate bottlenecks in the underlying content hosting service. • Preliminary support for the integration of JSR-170 repositories • Dropboxes – Students and Instructors can now choose to email each other when they upload to a Dropbox. – Instructors can now see a visual indication of which folders contain recently updated content. – Removal of inappropriate options from Dropbox interface.

Section Info • Download or print a roster list that provides each student's section memberships. • Better enforcement of the maximum section size.

Roster • New UI with a separate tabular view for profile and official institutional photos. • Integration with Course Management API to display enrollment status information. • Expanded permission scheme to retain the Roster's general use purpose while incorporating course-specific features. • Significant performance improvements.

Provisional Projects • Page Order Helper – Improved keyboard accessibility. – Added support for page grouping. • Podcasts – Permissions now a reflection of permissions in Resources.

Provisional Projects • Linktool – Updated documentation. – Now deploy Sakai. Signing. jws to webservices by default. – Added placement id to list of parameters passed. – Support for specifying additional parameters in the tool setup or URL. – Cleaned up tool formatting and validation. – Added new default verification script.

Provisional Projects • Search – Addressed critical indexing errors for clusters with a journaled indexer. – Reduced memory usage in indexers. • Data Warehouse – Separated from OSP to realize its general usefulness for reporting functionality.

Cross-Project Activity Highlights • Accessibility – Outcomes from 2. 4 accessibility review influenced many changes and improvements for 2. 5. • Internationalization • User Interface – “More” Tab – Tool Icons – PDA/i. Frameless Portal

Internationalization Current Underway • • • • Traditional Chinese • Danish • German • Hebrew • Mongolian • Portuguese • Slovakian • Turkish • Vietnamese Arabic English/UK (new) Catalan Simplified Chinese (updated) Dutch (updated) French/France (new) French/Canadian (updated) Japanese (updated) Korean (updated) Russian (new) Spanish (updated) Swedish

Project Coordination Meeting 28 -29 June 2008 http: //confluence. sakaiproject. org/confluence/x/q. QDa • Face-to-face opportunity to facilitate information sharing and collaboration among resource stakeholders • Over 40 participants from over 20 organizations 32

Main Topics of Discussion • • • Project Updates Beyond Sakai 2. 6 Kernel Minor and Maintenance Releases Tools Statuses (Core/Provisional/Contrib) Subversion and Maven Authoring (Content Authoring) Internationalization Static Code Review Large-scale Sakai Archive/Delete/Export/Import (Defered) 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 • m. Sub – Massively inclusive Subversion – – Facilitate sharing of customizations Increase-of-contributing to trunk Simplifies organizational merges No artifacts • Versioning – Remove M 2 – Snapshot – next versioned release of Sakai (e. g. , 2. 5. 1 SNAPSHOT) 36

Authoring (Content Authoring) • Demos – – – Open. Syllabus Mark Up e. Portfolio Page Composer Cam. Tools Widgets Sousa Simple Page Tool • Discussion – – 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 I 18 N 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 l 10 n 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 “Sakai. Bogo. Bug” metric for the scorecard – Further discussion on global commit rights to address specific Bug Report issues 39

Kernel • Google. Doc: http: //docs. google. com/Doc? id=dp 3 hj 8 r_9 fz 2 mrkdz • 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 40
