categories

Type Array of Strings
Mandatory No

The categories member is an array of strings defining the names of categories that the application supposedly belongs to. There is no standard list of possible values, but the W3C maintains a list of known categories.

Note: categories are used only as hints for catalogs or stores listing web applications. Like search engines and meta keywords, catalogs and stores are free to ignore them.

Note: categories values are lower-cased by the stores and catalogs before processing, so "News" and "news" are treated as the same value. Developers are encouraged to use lower case in the first place.

Example

"categories": ["books", "education", "medical"]
