Do we know about JRD and how it compares to JSON-LD? I was following the development. At some point the question came up whether JSON-LD should be used instead of JRD. I thought it wouldn't make much sense. It would have been rather trivial to change the format to use JSON-LD but the working group was already working two years on it and was close to finalize it. Furthermore JRD was supposed to map more or less directly to XRD. Webfinger is a simple discovery protocol. You can use it, e.g., to find the blog of a person if you just know that person's email address. The trick is that you would do something like GET /.well-known/webfinger? resource=mailto%3Asandro%40w3.org HTTP/1.1 Host: w3.org To get the JRD document for sandro@w3.org. Theoretically you could use it to serialize RDF but that would require rules defining how to interpret the data. To include statements about more than one subject, you would also need to redefine the whole format. Obviously, advanced features such as data typing or I18N are missing completely. So, to sum it up, yes I do think it is similar in certain regards but focuses clearly on one specific use case (discovering data for accounts that have no dereferenceable URI) whereas JSON-LD is much more generic and can be used for a plethora of applications.
