Ring application, successor of Page Relations, is available in version 1.0. It is meant to ease the creation of specific relations between pages, by using relations such as: “is a”, “is connected to”, “has author”, etc. For example, it can be used to state that “[The Jungle Book] [has author] [Rudyard Kipling]” or “[Rudyard Kipling] [is a] [person]”. Pages can then be explored along the defined relations using the XWiki Solr faceting capabilities. It could also possibly be seen as an alternative way to program applications by focusing more on reusable properties rather than on classes.
Feedback welcome + cheers
