2. Shared Workbooks
• Think “Track Changes”, but concurrent
multi-user editing
• Real time updates & conflict resolution
• Enables “track changes” feature
• Supports revision history log
3. How It Works
• Changes are written as separate parts
within the package
• A log table (revisionHeaders.xml) tracks
when changes are made, and the
relationship id to the revision details
• The application scans the log table for new
changes and pulls them into the workbook
