用例

书籍（和其他物品）有时包括折页或纸张，例如历史作品中的地图。在数字化过程中，折页可能以其折叠和展开的状态被捕获。

在前面的专题中，在单一视图中的多个图像选择中，翻页被作为同一视图的图像选择提供给用户。但请考虑这个例子。

在这里，这一页已经被捕捉到折叠和展开的情况。与前面的例子不同，这不是同一个视图。没有一个单一的IIIF Canvas可以用来表示这两个空间范围—我们不能在逻辑上将这两个图像放在同一个空间视图上。

虽然目前的例子和《单一视图中的图像的多重选择》中给出的例子明显不同，但建模的决定可能并不总是那么明显。会有一些案例可以用两种方式建模，这取决于出版商想要呈现的内容。

实施说明

展开的视图只是 manifest.items 所给序列中的一个额外 Canvas。

这些页面来自一本印刷好的分页书，它的行为 behavior 值可能是 paged，以便在支持该行为的查看器中生成正确的recto-verso-recto-verso 表示。如果我们在 Manifest 的项目 items 中插入一个额外的 Canvas，我们就会破坏这个序列，除非我们在 Canvas 上引入一个额外的行为 behavior 属性，让折页使用 non-paged 的值来表示它不是分页序列的一部分。

例子

这个例子改编自https://wellcomelibrary.org/iiif/b29346423/manifest，但为了表达基本观点，对其进行了大幅缩减。

清单 Manifest 被赋予了分页 paged 的行为 behavior。在没有其他限定词的情况下，这表示一个从左到右的序列，第一项是直角。

这个顺序是

封面
封面内页
折叠的，折叠的
折页，展开（给定行为 behavior 非分页 non-paged，表示它不构成清单分页序列的一部分）。
折页，折叠（背面）。
标题页
标题页的背面
正常的页数会在这里继续；为了简洁起见，在本说明书中被删除了
封面内侧
封面背面
Canvases上的 “非分页 non-page “行为还没有被浏览者支持，这使得它很难被可视化。在缩略图视图中产生的布局将看起来像这样。
