slc.linkcollection provides a little viewlet which displays links to other documents. If you click the links, the body of the referenced document is loaded into the current page using kss. By default the viewlet is placed between description and body text of a document. It shows only if the current context does reference some other documents.
>>> doc = self.portal.invokeFactory('Document', 'maindoc')
>>> maindoc = self.portal.maindoc
While logged in with Modify portal contents permissions, you will see a small edit icon where you can manage the references. They will be stored using annotations on the current context.
>>> from slc.linkcollection.interfaces import ILinkList
