Ordering In Action
This final example will both illustrate a second use of ldp:DirectContainers as well as detail the PCDM recommendation for how to handle ordering of resources.
The addtional predicates/relationships that will be used in this example are:
- ore:proxyIn
- ore:proxyFor
- iana:first
- iana:next
- iana:pref
- iana:last
...all of which are further described in the Portland Common Data Model.
As in the book example, begin with creating an ldp:DirectContainer, "orderProxies/", as a child of the book, "raven/", resource. This new DirectContainer will facilitate the auto-creation of triples that will define the membership relationship between the book, "raven/", and the proxies. Then, the new proxy resources within this DirectContainer will be used to establish an ordering of the books pages.
Note: This example assumes the previous creation of "/objects/raven/" and the cover and page resources from the Book example in this series.
