Together with Keystone we provide an example of a fairly basic type of portal. It is included as an example of how Keystone may be used, and it may be freely used and expanded as a starting point for new portals.

All of the pages of the portal are built around a shared structure, starting with a graphical bar at the top of the page to lend identity to the website. Underneath is a horizontal menu with certain fixed functions, including a search field. Below this, on the left side of the display, is the main menu, which also enables a language selection (if relevant). In the centre of the display is the content window, where the content of each page or document is presented. In the right-hand side is a column for news entries.

Clicking on a news item, the ``show more news'' link (displayed when not all news entries fit in the left-hand column) or the ``News'' menu-item in the main menu brings the user to a news page where the full content of all articles in the news directory are displayed.

Clicking on ``Help'' in the top menu brings the user to a system of help pages.

The ``Articles'' item in the left-hand menu brings you to a collection of local articles.

Typing in one or more keywords in the search field allows a free-text search through the portal. The administrator controls which directories should be searchable.

Articles and help documents are both based on the same document type, described by the schema document.xsd. This is a general-purpose ``article'' type with the quality that it can display a ``mini-menu'' of any sub-documents. This makes it possible to use this simple document type to construct complex structures of documents (such as encyclopaedia articles with multiple chapters).
