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.
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.
This diagram depicts the logical structure of resources and relationships of a collection ("poe") that consists of a book ("raven") that consists of three pages that are ordered. The following steps will walk through the process of creating this structure from the ground up. |
The ldp:BasicContainers are simply containers of other resources. BasicContainers can contain both other containers as well as ldp:NonRdfSources (or "binaries"). There are three PCDM types here:
Additionally, there are two PCDM relationships that indicate resource membership and file membership:
The descriptions of these resource types and relationships may be found in the detailed Portland Common Data Model page. |
