  1. HyperContent 2.0 JA-SIG Winter Conference December 5, 2005 Alex Vigdor, Columbia University

  2. What is HyperContent? • A platform for managing web sites in a distributed environment • A stable, scalable Java web application • A solution designed by and for Higher Education • Truly open source (MIT License) • A JA-SIG sponsored project

  3. Key Features • Edit and publish sites from a web browser • Store XML and publish XML, HTML or PDF • Keep a history of file revisions • Enforce granular permissions • Set up approvals, notifications and schedules • Publish locally, over NFS, FTP or SFTP • Automatically generate navigation and site maps

  4. A little background • Under continuous development since May 2002 at Columbia University • In production at Columbia since early 2003 • Sponsored by the JA-SIG since March 2004 • Implemented by 6+ other schools • Over 50 web sites currently published with v1.4 • v1.x implemented as a uPortal channel • Version 2.0 is a standalone web application with integrated web server, workflow engine, and cluster-capable batch processing

  5. Business model • Columbia has a web production group offering • project management • information architecture • graphic design • site implementation • training & support • Content experts author and publish their own sites • 5 central FTEs service dozens of departments • the eServices Integration group at the University of Hull offers a similar centralized web production service using HyperContent

  6. 2.0 Production Statistics November 2005 • 165,557 unique page views • 906 logins • 33 users • 12 active web sites • 5 restarts for bug fixes, 0 crashes • 311 batches published 28,040 items

  7. Content Authoring tools • WYSIWYG HTML & XML editing • Image convert, crop and resize • Drag & drop navigation and site map management • Dublin Core metadata • vCard contact information w/LDAP lookup • Multilingual spell checker • Upload & download arbitrary file types • Plain text editing for any text file type

  8. Architecture: Foundation • Repository API with versioning, locking, searching and metadata support • implementations include local, FTP & SFTP • Asynchronous processing engine • automatically distributes batch rendering and publishing jobs across server clusters • Event-driven workflow engine • Flexible XML scripts configure events, schedules, work queues, and sequences of commands that may send e-mails, trigger batch jobs, move work between queues, or execute any custom plug-in • Event & handler model supports loose coupling with other systems

  9. Architecture: Web Content • Extensible rendering pipeline configuration • filters for XML Includes, XSL transforms, Velocity templates, image resizing and watermarking, and more • persistent caching maximizes performance • recursive dependency analysis guarantees content freshness • Integrated HTTP 1.1 server • tuned for dynamic content management • HTML form input binding • bind individual inputs to specific processors • processors can expire inputs to prevent re-submission

  10. Architecture: Enterprise • Pluggable authentication • Uses JAAS LoginModules • Comes with JA-SIG CAS client • LDAP support • Grab display name, notification e-mail address • Manage contact info and directories on web sites • External web and file server support • Use network mounted drives, FTP or SFTP • uPortal support • Feed XML or XHTML to uPortal, use single sign-on for transparent security

  11. Roadmap • HyperContent 2.0 went final on December 2 • Upcoming development priorities include • Next-generation XML/HTML WYSIWYG editor • WSRP and UDDI portlet publishing • Integration with JA-SIG Groups & Permissions • JSR-170 repository support • WebDAV support
