This session will provide an overlook of the adoption of CMIS after one year from it’s ratification as OASIS standard. By providing several real life deployment success stories and integration scenarios, we’ll offer a close look to the many practical applications of the standard, especially leveraging the Apache Chemistry OpenCMIS implementation. We will conclude presenting highlights of the Alfresco CMIS strategy and discuss more advanced aspects of our CMIS implementation like performance and compliance.

PLAT-1 CMIS in the Real World
- 1. CMIS in the “real world” Or “Why bother writing custom APIs when you have standard ones”?
- 2. Agenda How did we get here? • From Babel to Esperanto • CMIS quick reference card How & What can I build? • Apache Chemistry state of the nation • What can I do with CMIS? • Application to Repository (a2r) • Repository to Repository (r2r) How people use CMIS? • CMIS & Alfresco • a2r CMIS product integrations • CMIS performances Demo (s)
- 3. Once upon a time… Builders of way too many… Towers of Babel !
- 4. We have a dream!
- 5. Did not take too long to get to… Initiated by CMIS Technical IBM, EMC Committee formed at & Microsoft CMIS V1.0 OASIS Published 1st Public 2nd Review Public CMIS Review Announced Late Sept Oct Oct Jan May 2007 2008 2008 2009 2010 2010 OASIS approved CMIS as an OASIS Specification on May 1, 2010.

- 9. Nice theory but … Tools anyone?
- 10. Open Source implementations of • Apache Chemistry (http://chemistry.apache.org) is the umbrella project for all CMIS related projects within the Apache Software Foundation. • Apache Chemistry provides libraries and frameworks for • Java (Client and Server) • Python (Client) • PHP (Client) • .NET (Client)
- 11. State of the Nation Java OpenCMIS (current version: 0.5.0) • Mature • High spec coverage and major testing • Client API / Server SPI • Goodies • In memory & fileshare test servers • Swing Workbench • OSGi bundles • OpenCMIS is available • as source code: https://svn.apache.org/repos/asf/chemistry/opencmis/trunk/ • as release package with all dependencies: http://chemistry.apache.org/java/download.html • via Maven: http://chemistry.apache.org/java/developing/dev-use-with-maven.html
- 12. OpenCMIS details
- 13. OpenCMIS details What does OpenCMIS give me? • Object oriented Client API • Ease of use and focus on domain model • Concept of session (CMIS is stateless) • Performance focus • Caching • Repository infos • Type definitions • AtomPub links • CMIS objects • Compression • CMIS XML compresses very well • Docs & Samples • http://chemistry.apache.org/java/developing/index.html • http://svn.apache.org/repos/asf/chemistry/opencmis/trunk/ chemistry-opencmis-samples/
- 14. Other clients Python cmislib (current version: 0.4.1) • Mature, tested against major servers • Available as egg, zip, tar.gz PHP lib(current version: unreleased) • Basic coverage of the spec • Used in a few productions site & for the Drupal integration DotCMIS (current version: 0.3) • Quite mature, good coverage of the spec • Single DLL • Requires more testing Browser binding (experimental on CMIS 1.1 branch)
- 15. All nice, but what can I build with CMIS?
- 16. CMIS use cases Application to repository (A2R) • ”App uses a content repository to handle content services” • Neat separation of frontend and content tiers • Examples: • Portal (e.g.Liferay) or Intranet (e.g. Drupal, Sharepoint) • Custom webapp or desktop application (e.g Office apps) Repository to repository (R2R) • “This is where content repositories talk directly to each other” • CMIS is flourishing, easy inter vendor communication • Examples: • Legacy Content Migration • Content Publishing or Archival Federated repositories • Mix of the 2 above: application talks to multi repositories http://wordofpie.com/2009/08/17/three-fundamental-cmis-use-cases/
- 17. CMIS & Alfresco (Open)CMIS is key to Alfresco strategy • CMIS client/server enhancements • Alfresco OpenCMIS Extension • OpenCMIS Server as of Alfresco 4.0 • Spring Surf OpenCMIS Client integration • Products • Web Quick Start • Alfresco iPhone / iPad Mobile App • Internal processes • Team (http://team.alfresco.com) & soon Partner (http://partners.alfresco.com) based on Drupal Alfresco CMIS integration CMIS allows seamless integrations with Alfresco • Social integration (Jive, Liferay, Drupal) • OpenCMIS clients / product integration (OpenWorkdesk)
- 18. Alfesco OpenCMIS Extension CMIS Extension for discovering / managing aspects • Aspects are an essential tool to model metadata in Alfresco. The CMIS specification does not define aspects or something similar, but it defines several extension points. • CMIS extensions are XML fragments placed in different parts of a CMIS object. (CMIS/Atom extensions are not fun to work directly with…) • “Alfresco OpenCMIS Extension” seamlessly merges aspect properties with object properties and provides interfaces to get, add and remove aspects. • It does that by replacing OpenCMIS' internal object factory with an object factory that is aspect aware. http://code.google.com/a/apache-extras.org/p/alfresco-opencmis-extension/
- 19. Alfesco OpenCMIS Server Starting from Alfresco 4.0: • Alfresco CMIS based on the OpenCMIS server framework • Why has it been re-implemented? • OpenCMIS is used by several CMIS repositories. • One code base for the AtomPub and the Web Services binding (and the Browser Binding). • Better CMIS specification compliance. • Better performance, less memory consumption, handling of big documents. What changes? • Old URLs still valid but deprecated • Generic clients should not notice differences • Alfresco Extension keeps on working! • JSON Browser binding prototype (disabled by default)
- 20. Alfesco iOS Mobile App iPhone / iPad app for Alfresco 3.4 + (or Team) • Heavily CMIS based (+ some custom Webscripts) • Initial Implementation of an Objective-C CMIS client • Code will be open sourced during DevCon Features • Read, open & save documents • Search documents • Upload and tag photos / video • Look for Marc
- 21. Spring Surf (Webscripts) and OpenCMIS Starting from Alfresco 4.0: • OpenCMIS client libs available in webscripts • Use cases • Repository • Light Migrations / Synchronization • Publishing • Web Tier • CMIS Enabled Frontend • Federated application frontend How to use it? • New JavaScript top level object: cmis • Three connection types: • Current Alfresco server (uses OpenCMIS local binding if possible) • Preconfigured connection • Web script configured connection
