In a social bookmark system like Delicious, tagging tends to be pretty free form, but it doesn’t have to be.
A new patent application from Yahoo! provides a slightly different look and feel for Del.icio.us. It covers many of the present day functionality of the site, but adds a different way of using tags that presently isn’t in use on the site.
The idea is to let people add some types of tags that can be easily used and understood by computer systems, and then possibly implemented into other types of applications.
For example, letting people tag pages with location information means that the system can then use that geographical information in maps, and mapping type applications. Including date and time information means that bookmarks can be integrated into calendars and timelines and other applications where time matters.
These “structured” tags add some possibilities by their association to formats (time, location, file type, etc) that hasn’t existed in Del.icio.us before. This kind of classification data also adds the possibility of presenting advertisements to the users of the social networking site.
The patent application also describes the present state of the social networking site:

A system is provided that permits the use of classification information that can be interpreted by a computer system.
To this end, a system and method may be provided for creating classification information that may be interpreted by a computer system. Such classification information may be associated with content, and permit a computer system to process the content based on the classification information.
In one example, classification information may be associated by a user, system, or process with a portion of content, and a computer system processes the content based on the classification information.
For instance, the classification information may cause content to be processed in a particular way, presented to a user by a particular application program, cause the content to be forwarded to a particular user, or otherwise influence how the content is handled.
