OSGi

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)

Java Content Repository (2)

JCR : CAS = JDBC : DB

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.

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.

Abstract Query Model

Language Bindings

JCR-SQL2 Query ::= 'SELECT' columns 'FROM' Source ['WHERE' Constraint] ['ORDER BY' orderings]

AQM type Query ::= Source source, Constraint? constraint, Ordering* orderings, Column* columns

Jackrabbit

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.).

Sling (2)

• Wiki

• Digital Asset Management

• Web Content Management

Sling (3)

Sling (4)

Dynamic Request Processing

▪ .esp, .ecma: ECMAScript (JavaScript) Pages (server-side execution) ▪ .jsp: Java Server Pages (server-side execution) ▪ .java: Java Servlet Compiler (server-side execution) ▪ .jst: JavaScript templates (client-side execution) ▪ .js: ECMAScript / JavaScript (client-side execution)
