Fedora4 (F4) implements the Linked Data Platform (LDP) W3C Recommendation. Additionally, the Portland Common Data Model (PCDM) has increasingly become adopted as a common content modeling approach in Fedora4.

LDP defines terminology and interaction models relating to linked data resources and servers. The "action" in inter"action" models should be emphasized, because LDP introduces two new concepts that enhance the actions within a linked data server, F4 in this case. These concepts are:

• DirectContainer
• IndirectContainer

These two container types have associated behavior that are highlighted and clarified here, in this guide. Two different uses of DirectContainers are illustrated in the Book and Ordering examples, respectively, and the use of IndirectContainers is described in the Collections example.

This guide is designed to describe the details of both LDP and PCDM in the context of F4 by walking through a simple example of a single collection, consisting of a single book that implements page ordering.

Note0: Although the following example uses specifically named resources, such as "poe" and "raven", production scenarios will likely use opaque identifiers/URLs by allowing them to be auto-generated by F4.
Note1: An easy way to stand-up an environment for executing the following REST requests is to use fcrepo4-vagrant. 
Note1a: F4 is deployed in the fcrepo4-vagrant box with the context "fcrepo". If you are deploying in another environment, you may need to change the "curl" requests and turtle files (*.ttl) below to reflect a different context.
Note2: Please use your Internet browser to inspect the results of each of the steps below! http://localhost:8080/fcrepo/rest
