Nuxeo EP Architecture Overview

Core Technologies
100% based on Java
Can runs as POJO or Java EE components
Bare JVM, servlet container or Java EE App server
OSGi-based Bundle and Component system
Advanced extension technology
Offering a highly dynamic plugin model
Integrates best of breed open source components
JBoss Seam, jBPM, Apache Shindig, Jena RDF...

Targets of Nuxeo EP architecture
Extensibility & Modularity at heart
At all levels (from core services to UI itself)
Loose coupling for building large systems
Configure, extend, integrate... don't hack around !
Agility to deploy and integrate in complex environments
Highly modular (choose your distribution)
High adaptable (run on a bare JVM as well as in Java EE containers)

Nuxeo ECM Services: extensible content services
Generic, configurable and extensible set of services
Nuxeo UI Technologies: UI building blocks

Features in layers Views and Actions for the target UI framework Service APIs and DTOs Provide JEE integration (Security, Transactions, EJB, Remoting ...) POJO implementation (Components, Services) Contributions to the Repository (Document types, lifecycles, listeners ...) One feature API Bundle Facade Bundle Core Bundle Core-Contrib Bundle UI Bundles UI Bundles

Extension Points
Extension points are used:
to configure services and components (XML contribution)
to extend services and components (contribute Java code or scripting)
to dynamically bind components together
Nuxeo EP uses extension points everywhere
built with its own technology
one model for the whole platform

Extension points XP A1 XP A2 Bundle A Bundle B Configuration via XML contribution Contribute Java Extension Component A Component B XML XML Java

Customization possibilities
Nuxeo EP is easily configurable
Almost all services are configurable (i.e. expose Extension Points)
Default UI (DM, DAM, CMF) is also very modular (Extension Points, Theme Manager, Views …)
Clean customizations that can be upgraded
You can use Nuxeo Studio
to save time in your implementation projects
to make customization easier
to do quick prototyping

Extension points Nuxeo Runtime Nuxeo Core Nuxeo Services Nuxeo UI Nuxeo UI Nuxeo UI Doc types Nuxeo UI Security policy Version policy Workflow Relations Connector Look Navigation actions Plug Plug Plug

Customization examples
Custom doc types, forms and life-cycles

Workflows
Enforce policy
listeners and content automation
custom security policies

Use Theme Manager
Change page models
Define page layout
Define style
Custom tabs or views
Custom content views
query to extract data
filter options
listing layout
Custom buttons
links or actions
call contextual custom code
…

Easy, elegant integration model
Nuxeo EP provides
Several APIs
Remotable/local, Java/language agnostic, different granularity levels...
Several integration paths and levels
Nuxeo EP is based on standards
Java, OSGi, JTA, JAAS, JMS, EJB3, JAX-RS, JAX-WS…
Nuxeo Studio and Content Automation is powerful
Easy to define business logic

Easy, elegant integration model
Thanks to this integration model
There is no need to touch Nuxeo's source code
Quick and efficient implementation of business requirements
Clean and sustainable technical integration in the SI
We think it maters!
A lot of external applications may need to produce or consume content from the ECM repository
ECM repositories usually needs to be integrated in the SI environment (security, audit, monitoring...)
See API section for some examples

Agile deployment
Only deploy the needed services
Make your own distribution
Deploy on multiple servers
Use clusters for scale-out / availability
Split in layers for optimizations or security
Deployment transparency
JBoss / Tomcat / Jetty / OSGi / Standalone
Cloud integration

Deployment examples
Easy clustering

Deployment examples
Use several distributions and dedicated servers

Deployment examples
Using multiple repositories

RSS, OpenSocial, OAuth, Publishing service ...

Integrate into Nuxeo EP
Package your application as Nuxeo Bundle
Declare OSGi bundle
Use nuxeo-deployer configuration
Your bundle can include web resources (servlets, filters ....)
Nuxeo nuxeo-services Your APP
