Runtime layer: OSGi infrastructure

Provides components and extension model

Provides deployment services

Core layer: embeddable document repository

Extensible storage oriented services

Service layer: an extensible set of ECM services

Generic and configurable set of ECM services

Client layer: UI building blocks

Pluggable actions and views management

Web or RCP based

Nuxeo EP 5 main layers

Deployment transparency

OSGi platform (Eclipse RCP) or JEE platform (JBoss AS)

components can be deployed client side or server side

Extensibility

Nuxeo components expose an Extension Point system

Components can be configured and extended

via XML descriptors

via Java classes

Flexibility

Choose components bundles according to business needs

Nuxeo EP 5 key architectural facts

Loosely coupled components

Event handler system: Core and Runtime

JMS Event handler: Service stack

Client Layer: Seam Events / RCP Events bus

Standards based

JEE: EJB3, JSF, JMS, JTA

Java: OSGi, JCR

XML: XSD (Document type definitions) , RDF (relations)

Open Source: Lucene, Jena RDF, JackRabbit, Seam, Restlets

Web: http and webdav

Web Services: JAX-RPC, JAX-WS, XML-RPC, REST

Nuxeo EP 5 key architectural facts

Multiple flavoured APIs

POJO local API for services

EJB3 remote API for services

Web Services API (JAX-WS and WS-Addressing)

REST API via Restlet Integration

WebDAV API

JS API for Ajax (via Seam Remoting / JSON)

Integrated build and packaging system

Maven 2.0 for build, test and packaging

Nuxeo deployer for components deployment

ECM service stack overview

Nuxeo EP 5 ECM Stack

Provides generic ECM services on top of Nuxeo Core

Services are loosely coupled and can be used independently

Most services provide 2 types of access

Local API: POJO

Remote API: EJB3

Service location is transparent via Nuxeo API

Framework.getService()

Services stack can be split on several JVMs

Platform layout can be configured via XML
