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. |

Here we will begin to walk through the mechanics of creating the structures that will facilitate creation of the book and its pages.
Where "pcdm-object.ttl" follows:
Second, create the nested "raven/" pcdm:Object, which is also another ldp:BasicContainer.
Lastly, create an ldp:DirectContainer, "pages/" that will facilitate the establishment of relationships between "raven/" and its constituent pages.
Where "ldp-direct.ttl" follows:
An ldp:DirectContaner is an LDP construct that activates the creation of certain RDF triples when a new resource is added as a child of this container. We will see this in action next! |
