Renders the RDFa that your Drupal7 site is outputting in a graphical form.
This is something of a successor to graphviz_filter, although it has nothing to do with input filters any more.
Radically, it has very little to do with Drupal internals any more either. This tool just inspects your rendered pages and then parses the RDFa hints out of them, so you are really seeing what the search engines and semantic scrapers are seeing.
Current work is just using it to try and autogenerate site navigation diagrams and content relationships using HTML REL links and embedded metadata, but it can also expose data relationships such as A Drupal-managed staff directory showing team membership and heirarchy
Output options include
- basic RDF dump - a table of triples
- Raw 'dot' file syntax - as used by Graphviz and a large number of other graph tools
- PNG image
- SVG image
Traditional "RDF Graphs" are horrible computer-science things, but I've found that with only a little coercing, the graphviz renderer can be told to do a much nicer job of it.
