    37. Jackrabbit in a few words... JSR-170 (JCR) reference implementation Codebase initially donated by Day No user interface, few tools Infrastructure for Day’s products Used in more and more projects (ASF and elsewhere) dev@ (360) users@ (440) Tuesday, June 10, 2008 37
    38. Sling in a few words... RESTful application layer for JCR repositories. Scriptable, simple things are simple to implement. Servlet API - to the max. OSGi framework - extreme modularity, enterprise-ready. Tuesday, June 10, 2008 38
    39. Apache Sling architecture HTTP debugger filesystem browser standard custom servlets WebDAV Sling OSGi servlets and components server console javascript resource servlet/script OSGi bundles JSR 223 JSP Ruby resolution resolution scripting OSGi framework Velocity etc.. (Apache Felix) OSGi webapp JSR-170 API JCR repository OSGI and JCR based scriptable applications framework Tuesday, June 10, 2008 39

    51. Sling’s unique selling points Tight integration with JCR. RESTful processing Convention over configuration - convention over code! Scriptable (javascript, JSP, Ruby, Velocity, etc.) Both client-side and server-side javascript. Servlets and scripts are interchangeable. Integrated OSGi framework Extensible, hackable, reconfigurable and future-proof. Tuesday, June 10, 2008 46

    56. Final words Day is very happy about our relationship with the ASF. The open source way of doing things works for us, both internally and externally. Jackrabbit + Sling = solid foundation for all our products: WCM, DAM, Wiki, blogs, and more to come. Balance between open source and making a living is still a work in progress. incubator.apache.org/sling jackrabbit.apache.org www.apache.org Tuesday, June 10, 2008 48
