Link to Drupal development site

NOTE: Drupal is a development site so may reflect changes made AFTER the generation of the build used for the review. Some changes will be the result of review issue resolution, others the result of continued development work.

Library Package

In DDI 4, a group of classes within the Library related by a theme. The Class Library for DDI 4 encompasses the entire DDI 4.0 model, but without any specific schemas or vocabularies for Functional Views. Classes contain primitives and extended primitives and are the building blocks used to construct the Functional Views.

Functional View

In DDI 4, a functional view identifies a set of classes that are needed to perform a specific task. It primarily consists of a set of references to specific versions of classes. Functional views are the method used to restrict the portions of the model that are used, and as such they function very much like DDI profiles in DDI 3.*.
