Content Models The rough equivalent to Data Definition Language in Alfresco 

Everything is a node, nodes are typed Content Model is expressed in XML • Defines types, aspects, properties, associations, constraints • Cold-deploy most common, hot deploy possible Hierarchical • Types inherit from super types Extend the out-of-the-box model with your own 

Forms Forms are modeled in XML • Explorer: web-client-config-custom.xml • Share: share-config-custom.xml Form Service • Processes and persists form data • Filters for intercepting form data before and after form submit • RESTful API for retrieving form model as JSON 

Rules You can automate a lot of content processing using rules that trigger rule actions 

Rules save time Defined in the UI by end-users If this (criteria) then that (action) Associated with a folder • Can optionally be applied to sub-folders Can easily add your own custom actions to the list 

Web Scripts Roll your own REST API using this MVC framework or leverage the out- of-the-box URLs 

Roll your own REST API Web Script Framework used to declare a URL, bind it to logic, provide views • Model-View-Controller pattern • Controller implemented in server-side JavaScript or Java • Views implemented in FreeMarker Deployed to the repository or the classpath Can also have web scripts on the Share tier 

Out-of-the-box URLs Web script console lists all web scripts • http://localhost:8080/alfresco/service/index • http://localhost:8080/share/service/index Pay attention to the lifecycle • Lifecycle “internal” may change without warning Use CMIS or public API whenever possible 

CMIS CMIS is the preferred API for integrating with Alfresco 

Use CMIS for CRUD functions Important ECM industry specification managed by OASIS Alfresco uses OpenCMIS, the de facto standard implementation of the spec • Available at http://chemistry.apache.org All you need is a service URL • http://localhost:8080/alfresco/cmisatom (4.x) For Java, Python, .NET, PHP, Objective-C, Android libraries see Apache Chemistry 

Extensions Avoid changing files included with the Alfresco distribution 

Use AMPs to package extensions An AMP is a ZIP with a special folder structure, a manifest, and a funny name The MMT is used to deploy (merge) your AMPs with alfresco.war and share.war Use AMPs even when you do not intend to publicly distribute your customizations https://wiki.alfresco.com/wiki/ Packaging_And_Deploying_Extensions 

Debugging Use the source, turn up logging verbosity, leverage one of many consoles 

Developer, Heal Thyself Configure Eclipse for remote debugging Turn up logging in log4j.properties Turn on the server-side JavaScript debugger Use a client-side JavaScript debugger Use Florian Maul’s JavaScript Console Use the Node Browser Use the OpenCMIS Workbench Use SurfBug
