Templates and semantic forms help you to structure your wiki content, to speed up your work, to adhere to layout standards and to store and query data.
A template is “reusable content” that can be integrated into any page of the wiki. The template can be content-based (text template), structure-based (layout template), or a combination of both.
For example, think of an info box that looks identical on all pages, but contains different content on each page (layout template). A template can also be used as source for an article or for a portal page in the wiki.
