Extract hyperlinks from pptx about sparql.anything

[luigi-asprino]

A remodelling of the Facade-X interpretation of PPTx was needed to extract hyperlinks. In the previous implementation, slides contained shapes as slots, where each shape had a single slot containing the text of the shape. This avoids "attaching" annotations (e.g. hyperlinks) to individual pieces of text (as the text is a single mass).
Therefore, a bit more structure was needed to extract the hyperlinks.
Here is the structure extracted from this file

[ rdf:type  fx:root , xyz:Presentation ;
  rdf:_1    [ rdf:type  xyz:Slide ;
              rdf:_1    [ rdf:type  xyz:CENTERED_TITLE ;
                          rdf:_1    [ rdf:type  xyz:Paragraph ;
                                      rdf:_1    [ rdf:type  xyz:TextRun ;
                                                  rdf:_1    [ rdf:type  xyz:Text ;
                                                              rdf:_1    "This is a test presentation"
                                                            ]
                                                ]
                                    ]

] .

There is a deep nesting, I agree, but I don't see any other solution.

Can you also include a link to the source pptx?

@luigi-asprino, when is a 1.0.0-RC planned? I guess that will be the first opportunity to test PPTX hyperlinks.
