: Microdata Without Reviews I have not been able to find a clear issue on omitting reviews from Microdata. I understand that Microdata values for reviews will default to a certain number when

You are probably talking about Schema.org and not about Microdata.

Schema.org is a vocabulary (which can be used with various syntaxes, including Microdata), Microdata is a syntax (which can be used with various vocabularies, including Schema.org). (Related answers: 1, 2.)

So, Microdata doesn’t require anything like that. But Schema.org doesn’t require it either. It’s perfectly valid and allowed to specify only those properties you want. Schema.org doesn’t define required properties.

Schema.org consumers (tools, search engines, …) can, of course, "require" anything they want. For example, Google may say that they only show a Rich Snippet when particular properties are specified. That’s up to them, so it’s rather pointless to try to understand their reasons for that, as nothing can be done about it. For now, they decided it that way; it’s likely that they’ll support additional Rich Snippets in the future, so it may be the case that suddenly even "incomplete" (in Google’s view) Schema.org data will be used for displaying a Rich Snippet.

I am not sure of exactly what you are asking so I will try and answer it short and sweet.

Zero.

Okay. I will explain. AggregateRating, Review, and SoftwareApplication are all under CreativeWork and can be nested to create a cohesive review of software items. The AggregateRating is used to wrap individual Review(s) as you are used to seeing with stars. It is the AggregateRating that provides the stars. If there are no reviews then the value for reviewCount under AggregateRating would be zero along with ratingValue and therefore no stars.

It is confusing and there are some good examples on the new. However, use the Google Rich Snippets Tool to check any example before going down that rabbit hole. There are more bad examples than good ones. Check out schema.org for details. It is as clear as mud when you look at it but with some good examples it becomes clearer.

So to answer the omitting part, you would still create the microdata markup, but use zero as I have outlined.

To answer the defaulting part, not all values default. Some have to be specified. When you create your AggregateRating and Review(s) you will have to provide some values but not all.

I think some of the confusion you are alluding to is where no one has reviewed the software item - would it be of value to the user? Generally, an item that is not reviewed has zero stars and of no real value to the user. You would be right. However, if you have experience with the software item, you can enter a review.

Does this help?
