Answer the previous question mentioned in the blog post.
How does type restrict the type of field that stores the property value?
Remove the `type` item in the Thing property type form. I've made some progress. I can get the information from a specific Thing property entity. It contains the field value and storage information. It means it doesn't need to fill out the value of `type` in the bundle of the Thing property type. Here are several data examples of interfaces that are consistent with the Web Thing specification.
Example: Get all things
Example: Get a description of a Thing
3.3 Property resource
A property resource represents a single property of a device. Some property resources may be read only and some may be writable. The value of a property can be retrieved with an HTTP GET request and updated with an HTTP PUT request.
Example: Get a property
3.2 Properties resource
A properties resource represents all the properties of a device. The value of all properties can be retrieved with an HTTP GET request.
Example: Get all properties
