PLAT-1 CMIS in the Real World
The document discusses the development and application of the CMIS (Content Management Interoperability Services) standard, emphasizing its evolution and real-world use cases, particularly in integrating applications with content repositories. It highlights key tools and libraries, such as Apache Chemistry, and provides insights into how platforms like Alfresco leverage CMIS for content management and social collaboration. Additionally, it outlines various implementation scenarios and performance optimization tips for using CMIS effectively.

CMIS use cases Applicationto 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/

- 18. Alfesco OpenCMIS Extension CMISExtension 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 Startingfrom 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)
