The new 5.x version of Ontopoly has a number of features that earlier Ontopoly versions did not have, and which are not described in the documentation (yet). To help people see what is actually available Geir Ove Grønmo has written a set of slides about the new features, which you can see below:
We are working to get these features properly documented in the Ontopoly User Guide that comes with the product, but in the meantime this may be helpful. Issues have already been created for two of these features, views and the embeddable version, where you can find a bit more information.
If you have further questions, please use the comments or post to the mailing list.
