- 2. Nuxeo, who are we? ● Vendor of an open source software platform in the feld of Enterprise Content Management ● Love to create great software, fond of modularity, started to use OSGi 4 years ago to create server-side enterprise software... ● 10 years old, 500+ customers, 5000+ installations ● Sells support & maintenance subscription and added value software provided as a service ● Dual HQ Paris & Boston, offces in San Francisco ● http://www.nuxeo.com 2
- 3. Nuxeo Enterprise Platform ● The software we develop is an Open Source ECM platform known as Nuxeo Enterprise Platform (EP) ● A “platform” because you can use Nuxeo EP to develop your own customized ECM application ● We also provide Turn-Key pre-build applications based on Nuxeo EP already customized for different scopes: – Document Management (DM) – Digital Asset Management (DAM) – Case Management Framework (CMF) – … or simply Content Application Platform (CAP) for developers 3

- 8. In a nutshell ● Full-featured confguration & customization environment delivered as a Service ● Develop Faster: start fast, reuse, focus on your model and business logic, not on plumbing ● Deploy & Update Easily on your various platforms thanks to the Update Center & Nuxeo Marketplace ● Protect your investment: Forward Compatibility Guaranteed! No more upgrades that break your customization work. 8
- 9. What is Studio? ● A Web User Interface to confgure Nuxeo EP ● Easy to use Rich Client Interface – based on GWT ● Made for non technical people – Everyone can confgure Nuxeo EP ● Generates a bundle containing the confguration extensions (a JAR fle) ● Hides the complexity and the huge number of extension points provided by the platform ● Focus on confguring functionality and not on how the confguration is done 9
- 10. Some Background - Extension Points ● Nuxeo EP is an ECM platform made of hundreds of bundles and extension points ● Each bundle may defne one or more extension points ● Extension Points provide a way to confgure services from outside the host bundle. ● Any bundle may contribute new extensions to other bundles to confgure them ● Extension points are primarily used to confgure the application or to install new capabilities 10
- 11. Why Studio? ● Extension Points are great but are designed to be used by developers ● Require knowledge of the target service internals ● To customize a functionality you may need to defne tens of extensions ● Nuxeo EP already ships as a complete ECM product – ready to be used in production ● In most of cases you only need to confgure it through extensions to defne your content model, add your business logic or for branding the product ● This confguration task is usually made by non technical people 11
- 12. Why Studio? – Example ● Defning a new document type requires at least 4 extensions: ● Defne the document type (behavior, schemas etc.) ● Contribute XSD schemas used by the document type. ● Attach a life cycle to your document type ● Confgure document views (e.g. tabs in UI) ● Then you need to package your extensions as an OSGi bundle 12
- 13. Nuxeo Studio – the Solution ● To defne a new content type you need to create a new plugin that may contain many XML extensions ● Not diffcult for developers ● But diffcult for non technical people ● Nuxeo Studio is allowing you to focus on the feature you want to add and not on how to add it ● No need to worry about: ● How to create a new OSGi bundle ● How the extension point works and what the format is 13
- 14. Studio Internals - How it works? ● Defnes a confguration meta model on top of Nuxeo EP extensions ● Each confgurable object has its own meta model ● Meta models are stored on the fle system in a GIT repository ● Confgurable objects are versioned through GIT ● Generates an OSGi bundle containing Nuxeo EP extensions at user request ● The meta model is converted into Nuxeo EP extensions (an XML fle) ● Just install the generated bundle! 14
- 15. Benefts and Limitations ● Create Content Applications without coding ● Including Branding and Business Logic ● Anyone can create its ECM application! ● Install the Studio generated bundle at runtime ● Ensure backward compatibility ● Confguration meta model is maintained by Nuxeo ● Old Studio Projects will work on new Nuxeo EP versions ● Limitations - Extensions cannot be reverted back to confguration objects 15
