Datatype definitions

Greetings,

I am curious as to what the purpose of the datatypes on schema.org are.

For instance, take http://schema.org/Integer. If you load the web page at that address you will find no documentation on what values of that type are expected to be. The most you can find are properties where the datatype is used, and the descriptions associated with those fields might include an example such as “123” or “xvi” or “18MB". This is grossly insufficient if you wanted to, in general, parse and semantically understand the data of that datatype.

If you load the web page at http://schema.org/Person you will find a table of property, expected type, and semantic. Except for the lack of definition of datatypes, the documentation located here is sufficient for me to understand what a http://schema.org/Person actually is.

Thanks for your time,
Eric
