Why does Drupal Schema.org module include RDFa instead of microdata?

Question

Why does Google Structured Data Testing Tool show RDFa node data for Schema.org microdata? For example, see this example generated for the Drupal Schema.org module; this is an example of how to insert Schema.org microdata into your page, but the Drupal testing tool reports the microdata as rdfa-node. I thought Schema.org was a subset of microdata, which is different from RDFa? Has the testing tool just gotten confused?

Answer 1

As explained on the schema.org module for Drupal page, this module will output RDFa which is the syntax present in Drupal 7 core. RDFa is one schema.org syntax understood by Google parser, which is what it displays when you parse that page (rdfa-node). Microdata is another syntax for schema.org, if you prefer to use microdata with Drupal, you can use https://drupal.org/project/microdata
