Exported Physical Graphs - as exemplified by RSS 1.1, SIOC, and other RDF data syndication buttons you see across the Web of Hypertext 2. Embedded Physical Graphs - as exemplified by RDF/A, eRDF, and (X)HTML microformats that have existing GRDDL based XSLT stylesheets 2. Virtual Graphs - those generated from a plethora of none RDF data sources and exposed via Web Services and SPARQL Endpoints (X)HTML Microformats are going to be transformed into RDF in a variety of ways to produce either of the forms above. This is also the "sweet spot" for GRDDL and Micromodels in general. I will demonstrate this concept with SPARQL in the next day or so (i.e. using a (X)HTML page containing Microformats as the Graph URI for my SPARQL Query). This is something Danny Ayres has been seeking in a variety of recent blog posts re. SPARQL, GRDDL, and XSLT as a mechanism for demonstrating the Data Web in a simple but very powerful and relevant manner. As for the paragraph in question, it is best it gets massaged into shape via a Wiki style effort. Even better, why not look to the Wikipedia article re. the Semantic Web [1] (Tim and I have touched this document of late for instance, and it would be nice if others could contribute also).
