Working with Rosario workitem links in object model

As you know, Rosario comes up with rich linking abilities for workitems and object model to support it. Working with object model could be a bit tricky when it comes to comprehending directions of links and Durgaprasad wrote a nice blog on how to use the OM. Check it out here: https://blogs.msdn.com/dgorti/archive/2007/09/26/querying-on-workitem-links-through-the-api.aspx . Note that the actual querying for links based on criteria can be done with WIQL language.
