"Our recommendation at this time is to make JSON-LD our primary supported web services data format. It is quite flexible, and supports the self-discovery capabilities that we want to support."

PHPCR

The PHP Content Repository is an adaption of the Java Content Repository (JCR) standard, an open API specification defined in JSR-283. The API defines how to handle hierarchical semi-structured data in a consistent way.

slide-31
SLIDE 31

PHPCR is a collection of interfaces

slide-32
SLIDE 32

Same API, multiple repositories

  • Jackalope

– Apache Jackrabbit:

Java-based repository server, accessible through WebDAV

– Doctrine DBAL: pure-

PHP repository library

  • jackalope.github.com
  • Midgard2

– GObject-oriented

repository library accessible through PHP extension

– Python, JavaScript,

Java, ...

  • midgard-project.org/phpcr
slide-33

"Developers write against a single API Implementations can be chosen based

  • n deployment needs"
slide-34
SLIDE 34

Repository capabilities

  • Tree access
  • Access by UUID
  • Workspaces
  • Versioning
  • Multi-value properties
  • Queries: SQL2, QOM
  • XML import and

export

  • Permissions
  • Capability discovery
  • Observation
  • Locking &

Transactions

PHPCR

slide-37
SLIDE 37

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

Connecting to a repository: Jackrabbit

  • Start Jackrabbit:

$ java -jar jackrabbit-standalone-2.4.1.jar

  • Connect to repository:

This is the only repository-specific part

slide-41
SLIDE 41

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
