but our users hate the UI"

standalone, decoupled, and cohesive
PHP components that solve common
web development problems.

10. Create.js
Create.js is a comprehensive web editing
interface for Content Management Systems. It
is designed to provide a modern, fully browser­
based HTML5 environment for managing
content. Create can be adapted to work on
almost any content management backend.

no forms allowed”

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. PHPCR
The 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. PHPCR is a collection of interfaces

31. Same API, multiple repositories
●

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, ...

32. "Developers write against a single API
Implementations can be chosen based
on deployment needs"

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. “Simple stuff should be easy, but
complex stuff should still be possible”

35. PHPCR

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. Connecting to a repository: Jackrabbit
●
Start Jackrabbit:
$ java -jar jackrabbit-standalone-2.4.1.jar
●
Connect to repository:

38. This is the only repository-specific part

39. Working with the tree

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. Queries: SQL2

42. Queries: Query Object Model

43. Versioning: enable

44. Versioning: commit

45. Versioning: restore
