Hello, Most of you heard from the launch of the new format for microdata: Schema.org and my question is about the different types of Schema they provide. Our websites provide an overview of courses, visitors can search/filter training courses and most important: read peer reviews. Until now we formatted (the source) of those courses with the schema type "Product" because it allows us to provide search engines with metadata about reviews via the "Aggregrated Rating". Recently we updated the information about courses, to also provide start dates and locations to users, just like the schema type for: "Events". Because we would like to provide search engines also with both types of data I would like to know your opinion. Schema.org looks like not to support the Aggregated Rating for Events and vice versa for Startdates/Locations for the Product type. And combining the two Schema types also does not looks like an option because we can't put them on the same level like it should be. So what would you recommend to use for kind of schema type(s), are we able to use the 'Product' type next to the 'Event' type and so to combine them? Thanks a lot!
