A brief introduction to the CMIS spec and some tips and tricks for developers new to CMIS. Demos showed how to install and use cmislib, the Python API for CMIS, and OpenCMIS, the Java API. Both projects are part of Apache Chemistry. Originally given as part of an Alfresco webinar. Recording: http://blogs.alfresco.com/wp/webcasts/2012/01/getting-started-with-cmis-2/

Transcript

  • 1. Getting Started with CMISJanuary 2012Jeff PottsChief Community OfficerApache Chemistry cmislib lead
  • 2. Agenda• What is CMIS? – Brief description – Quick overview of the domain model• First steps using Apache Chemistry – Demos using cmislib (Python) and OpenCMIS (Java) – Demo using OpenCMIS Workbench & the Groovy Console• Tips & Tricks for New CMIS Developers• Where to learn more
  • 3. What is CMIS?• Vendor independent API for working with content repositories• Specification managed by OASIS – Domain model – Protocol bindings • Web Services Binding • ATOM Pub Binding • Browser (JSON) Binding (Coming in 1.1) – CMIS Query Language
  • 4. The Beauty of CMIS Presentation Tier REST SOAP ? Content Services Tier Enterprise Apps Tier ?
  • 5. Meet CMIS Consumer Client read write Services Domain Model Provider Content Vendor Management Mapping Interoperability Services Content Repository CMIS lets you read, search, write, update, delete, version, c ontrol, … content and metadata!
  • 6. Developed by 30+ ECM VendorsImplementations Already Available… Providers Consumers
  • 7. Use Cases Content Client Client Repository Content Content Content Content Repository Repository Repository Content Repository Repository • Collaborative Content Creation • Workflow & BPM • Portals • Archival • Client Application Integration • Virtual Documents • Mashup • DAM / WCM
  • 8. TypesDocument Folder• Content • Container• Renditions • Hierarchy• Version History • Filing Described by Type DefinitionsRelationship Policy• Source Object • Target Object• Target Object
  • 9. Type Definitions Object Property • Type Id • Property Id • Parent * • Display Name • Display Name • Type •Queryable • Required • Controllable • Default Value •… Document Folder Relationship Policy •Versionable • Source Types • Allow Content • Target Types Custom Type
  • 10. • Open Source implementations of CMIS• Apache Chemistry is the umbrella project for all CMIS related projects within the ASF – OpenCMIS (Java, client and server) – cmislib (Python, client) – phpclient (PHP, client) – DotCMIS (.NET, client)
  • 11. • Apache Chemistry started as an incubator project in May 2009 – Graduated to a top level project in February 2011.• Backed by Adobe, Alfresco, Nuxeo, OpenText, and SAP• OpenCMIS is a de-facto reference for CMIS and is also used by the CMIS TC to test new CMIS 1.1 features
  • 12. FIRST STEPS WITH CMISReal-world coding examples
  • 13. Notes on my setup• Alfresco 4.0.c Community• SomeCo content model (See ecmarchitect.com)• Mac OS X, Tomcat, MySQL, Eclipse• Java – OpenCMIS 0.6* – Alfresco OpenCMIS extension 0.2* – JDK 1.6.0_29• Python – cmislib 0.5 – Python 2.6/2.7 * Distributed with Alfresco 4 SDK
  • 14. DEMOInstalling and Using cmislibUse easy_install to install cmislib. Docs available here. :10
  • 15. DEMOUsing OpenCMIS to create, query, relate, & deleteThe code comes from the ecmarchitect.com custom content typestutorial, available here. Apache Chemistry OpenCMIS lives here. :10
  • 16. DEMOUsing the Groovy Console in the OpenCMIS Workbench :05
  • 17. TIPS & TRICKSA few tidbits for the developer new to CMIS
  • 18. Prefix cannot be null or empty• You may see this error when using the Alfresco OpenCMIS extension• It is due to a dependency problem• If you are using Maven, see this issue.• If you are setting an explicit classpath, refer to the CMIS classpath set in the Ant build file in the content types tutorial
  • 19. Using Alfresco CMIS extension withOpenCMIS Workbench• You must do this if you want to set properties defined in an aspect• Copy alfresco-opencmis-extension-0.2.jar to workbench/lib• Set the following on “Expert” tab:org.apache.chemistry.opencmis.objectfactory.classname=org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl• Click “Load Repositories” before leaving the expert tab
  • 20. In Alfresco 4 the CMIS URLs havechanged• In Alfresco 4, OpenCMIS is now the CMIS implementation – Use http://localhost:8080/alfresco/cmisatom instead of http://localhost:8080/alfresco/s/cmis – Consider the CMIS web scripts to be deprecated – You may see different results b/w the two URLs
  • 21. CMIS in server-side JavaScript*varcmisConnection = cmis.getConnection();varcmisSession = cmisConnection.getSession();folder = cmisSession.getRootFolder();print("Children of: " + folder.name + "(" +folder.id + ")");variter = folder.getChildren().iterator();while (iter.hasNext()) { print(iter.next().name);} *Broken in 4.0.c Community
  • 22. Experimental JSON binding in Alfresco 4 • Alfresco 4 includes an experimental implementation of the new browser binding • http://localhost:8080/alfresco/cmisbrowserhttp://localhost:8080/alfresco/cmisbrowserhttp://localhost:8080/alfresco/cmisbrowser/{repo id}/roothttp://localhost:8080/alfresco/cmisbrowser/{repoid}/root?includeAllowableActions=true&skipCount=0&maxItemshttp://localhost:8080/alfresco/cmisbrowser/{repoid}/root/cmis-demohttp://localhost:8080/alfresco/cmisbrowser/{repoid}/root/cmisdemo?selector=childrenhttp://localhost:8080/alfresco/cmisbrowser/{repoid}/root/cmisdemo?selector=object
  • 23. Working with permissions• ACLs are lists of ACEs• In Alfresco, group identifiers start with ”GROUP_”• You cannot break inheritance through CMIS, but you can determine whether an ACE is inherited or “direct”
  • 24. WHERE TO LEARN MORE
  • 25. CMIS Resources• cmis.alfresco.com includes a public CMIS server and links to CMIS resources• Read the CMIS specification• Apache Chemistry site has clients, lightweight server, documentation• Alfresco Extension for OpenCMIS allows you to work with aspect-defined properties• “Getting Started with CMIS” tutorial shows how to use cURL to hit ATOM Pub binding directly• Slideshare has some CMIS related presentations from DevConhere and here
