  27. 27. Symfony CMF The Symfony CMF project makes it easier for  developers to add CMS functionality to  applications built with the Symfony2 PHP framework. Key development principles for the  provided set of bundles are scalability,  usability, documentation and testing.

  29. 29. PHPCRThe PHP Content Repository is an adaption of the Java Content Repository (JCR) standard, an open API specification defined in JSR­283. The API defines how to handle hierarchical  semi­structured data in a consistent way. 
  30. 30. PHPCR is a collection of interfaces
  31. 31. Same API, multiple repositories● Jackalope ● Midgard2 – Apache Jackrabbit: – GObject-oriented Java-based repository repository library server, accessible accessible through through WebDAV PHP extension – Doctrine DBAL: pure- – Python, JavaScript, PHP repository library Java, ...● jackalope.github.com ● midgard-project.org/phpcr
  32. 32. "Developers write against a single APIImplementations can be chosen based  on deployment needs"
  33. 33. Repository capabilities● Tree access ● XML import and● Access by UUID export● Workspaces ● Permissions● Versioning ● Capability discovery● Multi-value properties ● Observation● Queries: SQL2, QOM ● Locking & Transactions
  34. 34. “Simple stuff should be easy, but complex stuff should still be possible”
  35. 35. PHPCR
  36. 36. In PHPCR, all content is stored in a tree of nodes Nodes have a name, a type, and a set of properties Nodes can also have child nodes
  37. 37. Connecting to a repository: Jackrabbit● Start Jackrabbit: $ java -jar jackrabbit-standalone-2.4.1.jar● Connect to repository:
  38. 38. This is the only repository-specific part
  39. 39. Working with the tree
  40. 40. About Node types● Node types determine what properties and what kind of child nodes a node can have● Some built-in types: nt:file, nt:folder, nt:resource, nt:unstructured● Node types can be amended with “mixin” types, like mix:lastModified, mix:language● Most repositories allow you to define your own types● Recommendation: Start with nt:unstructured, add more strict definitions when you know your data model
  41. 41. Queries: SQL2
  42. 42. Queries: Query Object Model
  43. 43. Versioning: enable
  44. 44. Versioning: commit
  45. 45. Versioning: restore
