Yes you are right of course.

Markus, thanks for sending this. It was indeed
        lightly attended today (I feared that would be the case given
        August vacation conflicts), but it was still a good discussion.

        

        One correction: your notes on the RDF graph topic said, "...
        then the XDI graph model could be implemented “on top” of the
        XDI graph model". 

        

        I think you meant, ".."on top" of the RDF graph model", yes?

Following
                  are the notes of the unofficial telecon of the XDI TC
                  held on:

              
Date:
                  Monday, 22 August 2016 USA

                Time:
                  10:00AM - 11:30AM Pacific Time (17:00-18:30 UTC)

              

              
The
                  TC operates under a
                    standing rule approved 17 July 2008
                  under which the TC does not hold regular official
                  meetings and conducts all business by electronic
                  ballot only. Unofficial weekly meetings are held to
                  enable discussion among members but no business is
                  conducted nor actions taken.

                  Android App
              
Markus
                  reported that he continues to make progress on the XDI
                  Android app he has been working on, which demonstrates
                  the functionality of XDI link contracts, data sharing,
                  and messaging. Markus is currently focusing on
                  improving the app’s user interface.

              RDF
                  / XDI Compatibility
              
Markus
                  explored an idea about how to adapt the XDI graph
                  model to RDF in cases where the constraint is to start
                  with the RDF graph model. Markus pointed out that we
                  have always assumed that the mapping of an XDI graph
                  to an RDF graph is:

              
                

                  
XDI
                      literals are RDF literals

                

                

                  
XDI
                      relations are RDF properties

                

                

                  
XDI
                      contexts are RDF resources with a specific
                      relationship.

                

              
              

              
Markus
                  had the idea that if the constraint is that an
                  implementation must use the RDF graph model, then the
                  XDI graph model could be implemented “on top” of the
                  XDI graph model. 

              

              
For
                  example, =markus would be a resource and
                  <#email> would be a resource and then the
                  literal would be the email value. 

              

              
Markus
                  suggested that you can define a profile of RDF that
                  consisted of several key mappings:

              
                

                  
A
                      constraint that an RDF graph could have only one
                      predicate for a literal (to maintain the unique
                      addressability).

                

                

                  
A
                      single URI representing context.

                

                

                  
A
                      single URI representing unique instances (to
                      replace blank nodes).

                

              
              

                

              
The
                  end result of this thought process could be a graph
                  model that is 100% compatible with RDF but still makes
                  it possible to use XDI identifiers and XDI syntax.
