An os_meta_info is specialized page meta-information that can be added to an os_head . os_meta_info specifies whether its information must be implicitly understood by the receiver, such as an HTTP server or a browser, or whether the information should be used as the content for a defined HTTP response header, such as "


Keywords

An os_meta_info is described by a name and a content. The name and content are specified in the constructor and can be modified through the name() , content() , and http_equiv() member functions. Through its name/content pair, an os_meta_info provides a means to discover that data exists within a page, how it might be accessed, and its content, quality, and features. The method by which meta-information is extracted and how it is used are left strictly to the HTTP server or a browser.

An os_meta_info should not be used within an os_head when a specific element like an os_title would be more appropriate.
