Got content?

What are you going to do with it?
● Write it● Editors● Business representatives● UCG (User Generated Content)
● Process it● Transformations● Business processes● Branding
● Store it● Data vs metadata● Structured and unstructured● Archival and categorization
● But who cares about content which nobody will read? :)
● So fundamental step is...
4
...Delivery!!!
9
ECM and Content Delivery
● ECM Trends in last 3 years● Standardization with CMIS● Commoditization of the cloud● Everything is content!
● Content Delivery trends● Socialization of content ( 2 way channels )● Write once --> Deliver Everywhere (Servlet, Portlet, OpenSocial, etc.)● Lightweight frameworks
● Alfresco in 2007 was offering a JSF client● Hard to customize and not easily remotable● Hardcore java skills required --> rapid application development● Alfresco community demands a new way to deliver content
● Idea: Tailor make a content delivery framework for Alfresco● Component based page composition● Open Source● Open Standards based● Scriptable and extensible

Spring Webscripts and Surf
11
Genesis of a framework
● 2007 ● Alfresco 2.1 introduces Alfresco Web Scripts
• Micro MVC ReST framework• Scriptable - Control in JS or Java• Templates in Freemarker
● Started development on so called Alfresco Web Framework based on Web Scripts
● 2008● Alfresco Web Framework is completed● AWF renamed to Alfresco Surf● Alfresco Share (Alfresco collaboration interface) is based con Alfresco Surf
● 2009● First contacts between Alfresco and Spring Source● Alfresco Webscripts and Surf integrated with Spring MVC● Alfresco Surf and Webscripts contributed as Spring Webscripts and Spring Surf
● 2010● 3 Milestones released (latest 1.0.0-M3)

Spring Web Scripts
13
Anatomy of a webscript
Description document
An xml file which describes the Web script's properties, for example its URI and HTTP method
binding. The name of this file must comply with the Web Script Framework as follows:-
<web script id>.<http method>.desc.xml
For example: foo.get.desc.xml
Controller script
A JavaScript file which contains the logic of the Web script. Its output on execution is a model to
render in the response template. The name of this file must comply with the Web script
Framework as follows:-
<web script id>.<http method>.js
For example: foo.get.js
Response template
A FreeMarker template which renders the output response. The template has access to the model
generated by the controller script, and the Web script's invocation context.The name of this file
must comply with the Web script Framework as follows:-
<web script id>.<http method>.<format>.ftl
For example: foo.get.html.ftl

Spring Surf
● What Spring Surf is?1. A set of Spring MVC View Resolvers
• Page, Component (Webscript)• You can add your favorite Controller
2. A page composition framework• Modeling standard component based web engineering concepts• Pages, Templates, regions, components
3. Advanced remoting facilities• Modeling standard component based web engineering concepts1. Pages, Templates, regions, components
● A set of developer productivity tools• Spring Tool Suite integration1. Spring Roo extensions• Self documentation for Webscripts and Surf
1. What Spring Surf is NOT?● A Spring MVC controller (all in the view)1. Alfresco specific ● Being bought by Oracle :)

And the content?
● Where can we “suck” content from?● Obviously Alfresco (pre-configured endpoint)● Any source for which we configured a triplet
[authenticator, connector, endpoint]
● CMIS offers a new way to look at Content Repositories● CMIS is the SQL for content management● All major ECM vendors are implementing CMIS
• Alfresco / Sharepoint / Documentum / Filenet / Oracle● Most open source delivery frameworks are riding the CMIS horse
• Drupal / Liferay / Django / Joomla ● But how can we have Surf and Webscripts speak CMIS?
● Apache Chemistry OpenCMIS is the answer!
