a simple open source application management platform
starting with a small CMS nucleus
the Idea
the intention
adaptTo() 2016 3
▪ AEM ▪ huge, heavyweight, expensive
▪ but (1) - a nice template
▪ but (2) - needs simplification… ▪ no ‚staging‘ for I18N (no MSM)
▪ no different instances (author, publish), no replication …
the approach
4
▪ Versions
▪ JCR defines a versioning api
▪ not really used by sling based applications
▪ let’s use this for content staging…
▪ use the ‚versionable’ mixing type
▪ each page content node is ‚versionable‘
▪ each asset original node is ‚versionable‘
the releases
5
▪ there is a new object bundling the pages:the ‚Site‘
▪ the site manages releases(and some other things like mappings rules and langauages)
▪ ‚versionables’ can be assigned to releases
▪ one release is marked as the ‚public‘ release
