4. Java Content Repository (1)
• Content Repository API for Java Technology
Specification
• Java Content Repository 1.0 (JSR-170)
• Java Content Repository 2.0 (JSR-283)

5. Java Content Repository (2)
JCR : CAS = JDBC : DB

6. Java Content Repository (3)
• Repository: is composed of one or more persistent workspaces.
• Workspace: directed acyclic graph of items where the edges
represent the parent-child relation.
• Item: either a node or a property.
• Node: a node can have zero or more child items.
• Property: can contain zero or more values.
• Value: the content is stored in the values of the properties.

7. Java Content Repository (4)
• Path: identifies the location of an item.
• Identifier: every node has also an identifier.
• Property types: a property can be a primitive type or a pointer to a
node.
• Node Types: a node type defines a certain structure.
• User: the user accessing the repository.
• Session: the session associated to the user, defining also
authorizations.

11. Sling (1)
• REST based web framework.
• Content-driven, using a JCR content repository.
• Powered by OSGi.
• Scripting inside, multiple languages (JSP, server-side javascript,
Scala, etc.).

12. Sling (2)
• Wiki
• Digital Asset Management
• Web Content Management
