ThinCMS: A WPCML Editor Prototype
 • DHTML, XSLT, JavaScript
 • My favorite part of the project
 • Push the web GUI envelope, both in
   terms of technology and usability
 • Multiple treeviews of site
 • Ongoing effort to add features and
   improve usability
 •   Create XHTML site design
 •   Separate design into XML and XSLT
 •   Define reusable elements
 •   Build sitemap skeleton
 •   Build pages from templates
 •   Publish pages
 •   Maintain
Future Directions
 • Versioning
   – using DB or DeltaV
 • Workflow
   – author, editor, publisher roles
   – scheduling and notification
   – reports
 • GUI additions
   – preview interaction
